Suppose that 11 inches of wire costs 44 cents. at the same rate, how much (in cents) will 8 inches of wire costs?

8 inches of wire costs $0.32

Step-by-step explanation:

Find the cost for one inch of wire. Divide the cost with the inch:

44/11 = 4

one inch of wire costs 4 cents.

Now, find the cost for 8 inch of wires. Multiply 8 with 4

8 x 4 = 32

8 inches of wire costs $0.32

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
