Find the missing number so that the equation has infinitely many solutions. – 5x–19= (Blank)x–19
Answer:(number)=-5
Step-by-step explanation:
You can use simple logic in order to solve this equation.
An equation that has infinitely many solutions will have the same exact numbers on both sides
Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true
The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

You borrow $10,000 to buy a car. The simple interest rate is 3%. You pay the loan off after 6 years. What is the total amount you paid for the loan?
Answer:
The total amount of money needed to pay off the car after 6 years would be $11,800.
Step-by-step explanation:
Write down the facts:
The car costs $10,000The interest rate is 3%And you finished paying the loan off after 6 yearsInterest = $10,000 * 0.03 * 6
This being $10,000, 3% interest rate and over 6 years.
Interest= $1800
This amount we found is the additional amount (interest) you have to pay with the $10,000. Now, to find the total amound we add the interest and $10,000.
Total amount = 10,000 + $1800
Total amount = $11,800
Therefore the total amount paid over 6 years (including the 3% interest rate) would be $11,800. I hope this helped!!!
$11800 is the answer
Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
I hope that helps!
Answer:
6:59am
Step-by-step explanation:
1 hour and 33 minutes = 93 minutes
55 minute ride to museum
93+55=148
60 minutes in 1 hour
148 divided by 60 = 2 hours 46 minutes
Time Left: 9:41
9.41-2.46
6.59
They left at 6:59am

Answer:
40 in.²
Step-by-step explanation:
First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):
A=1/2(bh)
A=1/2(3x4)
A=1/2(12)
A=6
6x4=24 in.²
Next, you have to find the area of the square:
A=bh
A=4x4
A=16
Now, add 24 and 16 together to get your answer of 40 in.².

Alice has three boxes to carry. One box has of mass of 1.453 kilograms. The second box has a mass of 3.8 kilograms. The third box has a mass of 11.39 kilograms. What is the total mass of the three boxes?
Answer:
16.643 Kilograms
Step-by-step explanation:
Total means the sum of the number in this situation so first, you add
1.453 kg and 3.8 kg = 5.253 kg
then you add
5.253 kg and 11.39 kg = 16.643 kg
so the answer is 16.643 kilograms.
Answer:
16.643

How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.The slope and the intercept for the function in this problem are given as follows:
Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.Hence, the predicted cost for a month with temperature of 25ºF is given as follows:
y = -1.22(25) + 96.20 = $65.70.

A cooking magazine shows a photo of a main dish on the front cover of
5 out of the 12 issues it publishes each year. Write and solve a proportion
to determine how many times a photo of a main dish will be on the front
cover during the next 5 years.
Answer:
Step-by-step explanation:
Based on the number of times the photo appears per year, in 5 years it will appear 25 times.
Every year, the photo in question appears 5 out of 12 times.
If there were 5 years therefore, it would appear:
= Number of times per year x Number of years
= 5 x 5
= 25 times
In conclusion, the photo of a main dish will appear 25 times in 5 years.

Well anyways i hope this clears your concepts :D
Answer:
Step-by-step explanation:
EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).
Angle G remains the same at 55 degrees.

Scale factor for the triangle = 1/4
Value of y = 28cm
