X= -530
This is because:
2(x+60)+2(30)=200
•distribute the 2s into each parentheses
2x+1200+60=200
•combine like-terms
2x+1260=200
•isolate 2x by subtracting 1260 from both sides of the equation
2x=200-1260
•subtract 1260 from 200
2x= -1260
•divide both sides by 2 so you can have x all alone
2x/2= -1260/2
Hence
x= -530
Answer:
W = 16 feet
L = 19 feet
Step-by-step explanation:
We'll assume this is a rectangular garden.
Let L and W be the width and length, respectively.
W*L = Area = 304 ft^2
L = W + 3
Use this last expression in the first:
W*L = 304 ft^2
W*(W+3) = 304 ft^2
W^2+3W = 304 ft^2
W^2+3W - 304 ft^2 = 0
W = 16 and - 19. We'll assume we're in the current galaxy, so we can ignore the - 19 feet.
<u>W = 16 feet</u>
<u>L</u> = 304ft^2/16ft <u>= 19 feet</u>

Step-by-step explanation:
Answer:
92
Step-by-step explanation:
x= the ideal mark for his third test
100 + 63 + x/3 = 85
163+x=85x3
163 + x = 255
x=92
He would need to get at least a 92 to have the 85 average.
