A) write an equation that relates cindys age to her dads age .
B)determine if 42 is a solution to the equation. Show
your work.
C) explain the meaning of your answer in part B.
Answers
cindy=2
so 28-2=diffirance in age=26
A. dad-26=cindy
cindy=dad-26
dad=cindy+26
so since cindy=18
dad=18+26=44
B. if dad =42=cindy+26 so
42=x+26
subtract 26 from both sides
16=x
cindy =16 if dad =42
C. so the number of years apart they will be will always be 26 (until one of them dies)

1 yard = 3 feet.
So if we take 14 feet and multiply that by 3 we get 42 feet.
42/3 is equal to about 14 yards in total
So the answer is 14 yards.

The answer is b: -1
Step-by-step explanation:
x + x + 2 + 2x = -2
Collect like terms
x + x + 2x = -2 - 2
4x = -4
Divide both sides by 4
x = -4/4
x = -1

You are looking for how many miles the car went in 1 hour. You know it went 500 miles in 6.7 hours. To find how many it went in 1 hour simply Divide 500 miles by 6.7 hours.
500 miles/6.7 hours = ____ miles in 1 hour
Final answer:
The average speed of the winning car in the 1911 Indianapolis 500 race was approximately 74.63 mph. This was calculated by dividing the total distance covered (500 miles) by the total time taken (6.7 hours).
Explanation:
The subject of this question is Mathematics, specifically dealing with the calculation of average speed. The average speed is calculated as the total distance traveled divided by the total time taken. From the question, we know that the car covered a distance of 500 miles in 6.7 hours. Therefore, the average speed can be calculated as follows:
- Dividing the total distance covered, 500 miles, by the total time taken, 6.7 hours.
- Perform the division: 500 ÷ 6.7 = 74.63 mph.
The winning car's average speed in miles per hour, rounded to the nearest hundredth, is 74.63 mph.

Answer: I believe the answer is A.
Step-by-step explanation:
It is 1/2 throughout the line
It is 2 throught the line
The slope from point O to point A is 1/2 time the slope of the line from point A to point B
The slope from point O to pint A is two times the slope of the line from point A to point B
Answers
Point A is (4,2)
Point B is (6,3)
The slope is 1/2 throughout the line.
All three points are on the same line so they will all have the same slope.
Your answer is A. It is 1/2 throughout the line.
That means that if you find the slope from point O to point A, or point A to point B, or point O to point B, they will all have the same slope.
That eliminates answer choices C and D.
Point A (4,2)
Point B (6,3)
Your final answer is A. It is 1/2 throughout the line
