We have an equation: ?/17= 5/8
Cross multiply:
8*?= 5*17
⇒ ?= 5*17/8= 10 5/8
We only need 10 5/8 ft~
The answer: x=857 and y=-401
Set up the two equations
X+2y=55
2x+y=1313
Solve the system of equations by elimination
2x+y=1313
-2x-4y=-110
Add each of the corresponding terms together
-3y=1203
Divide by -3
Y=-401
Plug y back into one of the original equations
X+2(-401)=55
X-802=55
X=857
Answer:
6.1

I AM SOOOOO SORRY IF I GET IT WRONG!!!!
Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%
