Answer:
M=x/7 let's say M is what Micheal earned, and so he earns x dollars every seven days
L=2(M)
L=2(x/7)Let's say L is what Lee earned, she earned twice as much as Micheal so 2(x/7)
Total=2(x/7)+x/7
Total=3(x/7) the total earnings is the sum of x/7 and 2x/7 is 3x/7
i believe the answer is a
2(x + 1) = 10
2x + 2 = 10
2x +2 -2 = 10 - 2
2x = 10 (step 3)
2x/2 = 8/2
x = 4
Formula Given:
2(x + 1) = 10
2 Multiply by (x + 1) - Distribution Characteristic
2x + 2 = 10 to open the brackets.
Subtract 2 from both sides.
2x + 2 - 2 = 10 - 2 (equals subtraction property)
2x = 8 (justified in step 3).
Divide both sides by 2
2x/2 = 8/2 - property of equal division.
therefore
x = 4. (solved)
