The product of 8 and the sum of 4 and a number is 112. What is the number? Which equation could be used to solve for the number? 8 + 4n= 112 8x4 +n= 112 8(4 +n) = 112
Weegy: The product of 8 and the sum of 4 and a number is 112. The equation that could be used to solve for the number is: 8(4+n)=112. To solve: 8(4+n)=112; 32+8n=112; 8n=112-32; 8n=80; n=80/8; n=10 (More)

What is the slope of the line that passes through (-2, 7) and (4, 9)? slope = -1/3 slope = 1/3 slope = 3 User: y is 5 when x is 2.5, and y varies directly with x. Find y when x is 10. 5 7.5 12.5 20
Weegy: we can model this in terms of a linear equation. y=mx+b Since the question states that y varies directly with x, we know that m (the slope of the line) is 1. [ so: y=x+b Now, to solve for be we can sub in the two known values for x and y to complete our equation. 6=2+b b=6-2 =4 So our final equation for the line is: y=x+4 when x=5 y=(5)+4 =9 ] (More)

y is 5 when x is 2.5, and y varies directly with x. y is 20 when x is 10.

5/2.5 = y/10

2.5y = 50

y = 20
