What is the value of s in the equation 4(2s - 1) = 75 + 12?

s=91/8

Step-by-step explanation:

s=91/8

Step-by-step explanation:

To find the value of s, you want ot use your algebraic properties to isolate s.

4(2s - 1) = 75 + 12                         [distribute by FOIL]

8s-4=75+12                                   [add]

8s-4=87                                         [add both sides by 4]

8s=91                                             [divide both sides by 8]

s=91/8

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
