Find the error(s) and solve the problem correctly.
Sarah was asked to solve the following problem. Identify her errors and explain how to correct her mistakes.
Answers
Answer:
\(5x^3-18x^2+2x+21\)
Step-by-step explanation:
In the second step, -9x-21 should be 9x+21. This is because -3 in x-3, and -3x-7 in 5x²-3x-7 are both negative, so each term's product should be positive.
Also, in the third line, she wrote -3x²-15x² as -18x⁴ instead of -18x²,and similarly, she wrote -7x-9x as -16x² (however this is wrong anyway because step 2 was done incorrectly).
If we continued off from the second step with these corrected errors:
\(5x^3-3x^2-7x-15x^2+9x+21\\5x^3-18x^2+2x+21\)
Therefore, the correct simplification is \(5x^3-18x^2+2x+21\).

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

Answers
Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
We start by simplifying | −5 + 7 |:
| −5 + 7 | = | 2 | = 2
Now we can simplify each of the answer choices:
[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2
We see that only choice [2], when added to | −5 + 7 |, will equal zero:
2 + (−2) = 0
Therefore, the answer is [2] | +5 − 7 |.

hey...can we become friends??
Answer:
-16-5-22-45-45-146-19-44Step-by-step explanation:
This is an example for all orders of operations
1. We need to know P.E.M.D.A.S.
(P)lease(E)xcuse (M)y(D)ear (A)unt(S)ally2. PEMDAS is the acronym for the order in which you solve things:
(P)lease = Parentheses Ex: (x+y)(E)xcuse = Exponet Ex: \(x^{2}\)(M)y = Multiplication Ex: A×B(D)ear = Divide Ex: A÷B(A)unt = Addition Ex: A+B(S)ally = Subtract Ex: A-B3. Now that we know how the order of operations works let to a problem:
Ex: 7×8+(7×2+3)-(5+7)
1. First, we are gonna solve what is inside the parentheses.
2. We will do the first one : (7×2+3)
3. We are gonna use the order of operations to know what we solve first.
It looks like multiplication is firstso we do 7×2 and that =144. So now our parentheses should look like this:
(14+3)5. Now the whole problem should look like this :
7×8+(14+3)-(5+7)6. Now we solve (14+3). That =17. Our whole problem should be like this
7×8+(17)-(5+7)7. Now that we have solved the first parentheses we have to solve the second one: (5+7). that is 12. here is what it looks like in the whole problem:
7×8+(17)-(12)8. Now that we have solved the parentheses we can solve the next one. That is exponents. We don't have any exponents so we can go to the next and that is multiplication.
7×8That is 56the whole problem is now 56+(17)-(12)9. Now we have solved the multiplication we need to do the division. There isn't any so we can go to addition now.
56+17that is 73the whole problem is now 73-1210. Now we do the subtraction
73-12 and that equals 6111. The answer is now solved

Which graph represents the solution set for p + 3.6 < −5.8?
Answers
Answer:
Step-by-step use the number line numbers to help u better and where is the p?
Answer:
the first one
Step-by-step explanation:
First, solve the equation:
p + 3.6 \(<\) -5.8
do the inverse (opposite) of 3.6 which is -3.6 to both sides, like an equation.
p + 3.6 < -5.8
-3.6 -3.6
the 3.6s cross out on the left side. On the right side you are left with 9.4. This is your final inequality:
p < -9.4
Next plot your inequality.
Start by putting a point at -9.4 and not filling it in, because there is no possibility that p could equal -9.4.
Next check your sign. This is a less than sign so your possible number couldn't be more than -9.4. You would shade it to the left, because all the numbers on that side of the number line are less than -9.4.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

We'll add up the values in the bottom row of the table.
A value like +150 is the same as simply saying 150
The negatives stick around.
Adding up the values in that row gets us
150 + (-50) + 400 + 300 + (-175) + (-250) = 375
This indicates that over the entire 6 month period, the overall change is +375
---------
In other words, the initial investment (call it x) has increased by 375 dollars over the 6 month period.
We can then say:
x + 375 = 1500
x = 1500-375
x = 1125
