Hello there,
For this, we can simply take the values from the problem and plug them into the equation.
Since “a” is not part of the problem, we do not have worry about the value of a. When we plug in the values we get:
3(2) + 4(-2) = -2
Answer:
B. m - 2 = 28
Step-by-step explanation:
minutes it took Teri to run the race = m
Julie runs 2 mins faster than Teri and is expressed as m - 2 = 28 mins
Equation that can be used is:
m - 2 = 28
Okay okay okay
Answer:
r = ![\frac{30}{71}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B71%7D)
Step-by-step explanation:
12 -
= 5
6 × 12 × r × 6 -
= 5 × 6
72r - r = 30
71r = 30
r = 30 ÷ 71
r = ![\frac{30}{71}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B71%7D)
Answer:
14
Step-by-step explanation:
to find area, use the equation A=ab/2
a and b are the sides given. a=7, b=4
next, plug into equation
A=7×4/2
A=14
