The variables a through h all represent different numbers. Mentally find numbers that make each equation true. 3/5 x 5/3 = a3 5 ⋅ 5 3 = a

7 x b = 17 ⋅ b = 1

c x d = 1c ⋅ d = 1

-6 + 6 = e- 6 + 6 = e

11 + f = 011 + f = 0

g + h = 0g + h = 0

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

1; 35 is the ratio

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
