3m - 3 divided by 3 for m=8
Answers
Answer:
Either 7 or 23 - read note
Step-by-step explanation:
Substitute m for 8.
*Note: I'm not sure if anything is in parentheses so there are two possible answers depending on whether you want it done left to right or by order of operations*
Left to Right:
3(8) - 3 ÷ 3
24 - 3 ÷ 3
21 ÷ 3
7
Order of Operations:
3(8) - 3 ÷ 3
24 - 3 ÷ 3
24 - 1
23
3m - 3/3
3(8) - 3/3
24 - 1
= 23
3/3 is the same thing as 1

Consider the values shown. What place value must the answer be reported to?
7.273-12.4
1. Ones place
2. Tenths place
3. Hundredth's place
4. Thousandths place
I do not understand what is it asking could someone tell me the answer and then evaluate please
Answers
Answer:
2. Tenths place
Step-by-step explanation:
When you're concerned with the precision of a sum, the final value must be rounded to the precision of the least-precise contributor.
PrecisionThe numbers contributing to this sum are ...
7.273, with least significant digit in the thousandth's place.
-12.4, with least significant digit in the tenths place.
The smaller the place value of the least significant digit of a number, the greater the precision it has. The least-precise number will have the largest place value of its least-significant digit.
tenths > thousandths, so -12.4 has less precision
SumFirst of all, we compute the sum as though every contributor were exact. This is especially important when there are more than two contributors. With only two contributors, you get the same result if you round the more precise number first.
7.273 -12.4 = -5.127 . . . . . preferred method of finding the sum
7.3 -12.4 = -5.1 . . . . . . . . . . alternate approach for 2 contributors
Finally, we round that sum to the nearest tenth, reflecting the precision of -12.4:
sum = -5.1
__
Additional comment
As a general rule, this fixation on precision applies to quantities that are measured, estimated, or rounded.
For example, it doesn't make much sense to report a financial value to the penny if one of the contributors has already been rounded to the nearest hundred-thousand dollars. The amount could already be in error by up to $50,000, so precision to the penny is meaningless.
When working many kinds of problems, it can be useful to report answers to the same precision used for the problem values. In some cases, you are told exactly what precision to use for an answer (nearest integer, tenth, or hundredth). Where you are not told, it usually doesn't make much sense to use 6 significant digits for an answer to a problem with values given as one significant digit. However, it can be sensible to report the answer to 2 or 3 significant digits.
__
Here (in this problem), we're concerned with a sum. When you are computing a product or ratio, the rules are different. In those cases, the (least) number of significant digits in the contributors will determine the number of significant digits in the answer. Where mixed arithmetic (products and sums) is involved, the rounding of the final answer will depend on the final operation:
a(b+c) . . . the final operation is multiplication
ab +ac . . . the final operation is addition
As with all computation, the intermediate results should be carried to full calculator precision (unless directed otherwise). Only the final answer should be rounded to the necessary precision.

In this equation, to find the value of x, first, we have to subtract 1 from both sides,
\(\begin{gathered} x\div5+1-1=11-1 \\ \\ x\div5=10 \end{gathered}\)And then, multiply both sides by 5,
\(\begin{gathered} x\div5\times5=10\times5 \\ \\ x=50 \end{gathered}\)Hence, the value of x is 50.

caitlyn has $210 in her savings account and she has to pay her parents $5 each month.Santos has $90 dollars and he saves $5 dollars each month. At this rate, when will Caitlyn and Santos have the same amount of money ? How much will they each have?
Answers
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.

What sales tax, at a rate of 8.5%, must you pay on the purchase of a computer hard disk drive costing $250.75?
(Round to the nearest cent as needed)
Answers
Answer:
you must pay $21.32 in sales tax on the purchase of the computer hard disk drive.
Step-by-step explanation:
To find the sales tax you must pay on the purchase of the computer hard disk drive, we can multiply the cost of the drive by the sales tax rate expressed as a decimal. The sales tax rate is 8.5%, or 0.085.
Multiplying the cost of the drive by the sales tax rate, we get:
Sales tax = $250.75 x 0.085
Sales tax = $21.31375
Rounding this to the nearest cent, we get:
Sales tax = $21.32
Therefore, you must pay $21.32 in sales tax on the purchase of the computer hard disk drive.

Shahina has 550g of apples and plenty of other ingredients. can she make apple crumble for 6 people? explain your answer.
recipe list:
serves 8 people
700g apple
240g sugar
180 g flour
40g butter
Answers
Answer:
Yes, she can-------------------
As per recipe, 700 g apples is enough to make apple crumble for 8 people.
For 6 people Shahina needs:
6*(700/8) = 525 grams of applesSince she has 550 grams of apple, which is more than 525 grams, she can make it for 6 people.
Answer:
With 550g of apples and enough other ingredients, Shahina can make apple crumble for 6 people according to the given recipe.
Step-by-step explanation:
Let's compare the recipe requirements with the available ingredients to determine whether Shahina can make apple crumble for 6 people with the given ingredients.
The recipe serves 8 people and requires the following quantities of ingredients:
700g of apples 240g of sugar 180g of flour 40g of butterShahina has 550g of apples, which is sufficient to meet the apple requirement of the recipe.
Now, let's calculate the ratio of the other ingredients needed per person
For sugar:
240g / 8 people = 30g/person
For flour:
180g / 8 people = 22.5g/person
For butter:
40g / 8 people = 5g/person
Since the recipe is designed to serve 8 people, we can use these ratios to adjust the quantities for 6 people:
For sugar:
30g/person * 6 people = 180g
For flour:
22.5g/person * 6 people = 135g
For butter:
5g/person * 6 people = 30g
Comparing these adjusted quantities to the available ingredients, we see that Shahina has enough sugar, flour, and butter to make an apple crumble for 6 people.
tanya incorrectly says that the solution of the systems of equations is (-3, -2). what is the correct solution? 6g-3h=-3 7=h-5g
Answers
The correct solution to the system of equation is (-2, -3)
How to determine the correct solutionFrom the question, we have the following parameters that can be used in our computation:
6g-3h=-3
7=h-5g
Divide through 6g-3h=-3 by 3
so, we have
2g-h=-1
Make h the subject
h = 2g + 1
So, we have
7 = 2g + 1 - 5g
Evaluate the equation
-3g = 6
So, we have
g = -2
This becomes
h = 2 * -2 + 1
Evaluate
h = -3
Hence, the solution is (-2, -3)

What is -20/2(7 2/3)
Answers
The simplified form of -20/2(7 2/3) is -230/3.
To solve the expression -20/2(7 2/3), we need to follow the order of operations, which states that we should perform the operations inside parentheses first, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.
First, let's convert the mixed number 7 2/3 to an improper fraction.
7 2/3 = (7 * 3 + 2) / 3 = 23/3
Now, let's substitute the value back into the expression:
-20/2 * (23/3)
Next, we simplify the multiplication:
-10 * (23/3)
To multiply a fraction by a whole number, we multiply the numerator by the whole number:
-10 * 23 / 3
Now, we perform the multiplication:
-230 / 3
Therefore, the simplified form of -20/2(7 2/3) is -230/3.
