First we need to convert 3 3/8 into 1/8ths:
![3 \frac{3}{8} = \frac{27}{8}](https://tex.z-dn.net/?f=3%20%5Cfrac%7B3%7D%7B8%7D%20%3D%20%5Cfrac%7B27%7D%7B8%7D%20)
Now, we need to see how many times 3/8 goes into 27/8:
![\frac{27}{8} \div \frac{3}{8} = 27 \div 3 = 9](https://tex.z-dn.net/?f=%20%5Cfrac%7B27%7D%7B8%7D%20%5Cdiv%20%5Cfrac%7B3%7D%7B8%7D%20%3D%2027%20%5Cdiv%203%20%3D%209)
So we know he needs 9 telephone poles
Answer:
2.16, 3.45
Step-by-step explanation:
Answer:
(x,y) (9,4)
Step-by-step explanation:
-2x+7y = 10
x -3y = -3 (move x to the other side)
-2x +7y = 10
x = -3 + 3y (put in for x)
-2 (-3 +3y) +7y =10 ( slove for y)
6-6y +7y = 10
6+y = 10
y = 10-6
y = 4
go back slove for x
x = -3+3x4
x = 9
Answer:
<em>1x = 7</em>
Explanation:
Every week it grows 7 total inches. So, "x" stands for week. The equation "1x = 7" means 1 week equals 7 inches. This is the simplest equation to write this problem.
