Josh is doing sit-ups at a speed of 5 sit-ups per 7 seconds. (First find this speed). Three minutes (180 seconds) later, he is doing sit-ups at a rate of 7 sit-ups per 8 seconds (Second find this speed). What is Josh's acceleration?

Answers

Answer:

9.1*10^-4 sit-ups per square second

Step-by-step explanation:

Given data

Initial speed= 5/7 = 0.71 sit-ups per second

Time interval= 180 seconds

Final speed= 7/8 = 0.875 sit-ups per second

Hence the acceleration is given as

a= v-u/t

a= (0.875- 0.71)/180

a= 0.165/180

a=0.00091666666

a= 9.1*10^-4 sit-ups per square second

Answer:

x=2 and y=−1

Step-by-step explanation:

Let's solve your system by substitution.

4x+3y=5;2y=x−4

brainliest please?

Answer:

The answer to the system of equations is x = 2 and y = -1

Step-by-step explanation:

We can substitute the variables and see how they work with the equations.

2 (-1) = (2) - 4

-2 = 2 - 4

-2 = -2

4 (2) + 3 (-1) = 5

8 + (-3) = 5

8 - 3 = 5

5 = 5
