Answer:
length: 200
width: 65
Step-by-step explanation:
length: 3w + 5
width: w
perimeter = 2L + 2W
530 = 2(3w + 5) + 2w
530 = 6w + 10 + 2w
530 = 8w + 10
520 = 8w
w = 65
length: 3w + 5 = 3(65) + 5 = 200
width: w = 65
Answer: 1) 15 - 7 2) 5+c 3) m-7 4) x+16=23 5) x+8 6) 10÷w=7 7) 17+x=557 8) $12-x=$48
Step-by-step explanation:
Answer:
a)
b) l=19.2 units
Step-by-step explanation:
a)Let F represent the force and l represents the length of the wrench handle.
Then inverse variation relation is:
When we introduce the variation constant, we get:
From the question when F=96, l=12
The equation is
b) If a person can only exert 60 pounds of force on a wrench,then
Hence the length of the wrench must be 19.2 units
So the class must have at least 5 more students.
