5*12=60 so the answer is A.
3 3/4 - 1 2/5 = 47/20 or 2.35 or 2 7/20 So the answer would also be A.
I hope this helps!!!!!!!!!!!
Answer:
Part A: y = 4.5x + 22
Part B: 31 inches
Step-by-step explanation:
Part A:
the y-intercept appear to be at 22
the slope can be found by using the points (0, 22) and (4, 39)
m = <u>39 - 22</u>
4 - 0
m = 17 / 4 = 4.3 and this is close to 4.5
Part B:
plug in 2 for 'x' in the equation: y = 4.5x + 22
y = 4.5(2) + 22
y = 9 + 22
y = 31
if the ratio of sides is 2:3, the ratio of the perimeters will be the same
2 16
------- = ---------
3 P
Using cross product 2*P = 3*16
2P = 48
P = 24 inches
So it would be either 1/3 1/4 1/5 ect., ect.
2838=total
Women = 3X +5
Men = 4(3x+5)-3
Children= x
Men= 12x+17
Total= 16X +23
16x + 23 = 2838
16x = 2815
X = 2815/16
