Harley is 15 years less than seven times Marcy's age, so that means Haley + 15 = 7 * Marcy
Equation: (41 + 15) / 7 = 56 / 7 = 8
Marcy's age is 8.
Hope this helped =)
NO is 2 times LM
2(x+1) = 4x
2x + 2 = 4x
2 = 2x
1 = x
Plug that in for 4x
4(1)

Answer:
two million.
Step-by-step explanation:
A) Scale of map is 1: 30,000
This is assuming that it meant 1 centimetre = 30,000 metres, for it gives no other information.
Multiply 1 with 30,000: 30,000 x `1 = 30,000
30,000 metres is your answer.
B) Scale is 1 inch: 6 miles. You are given 2.5 inches.
Remember that 1 inch = 6 miles.
Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles
2.5 inch = 2.5 * 6 miles
2.5 inch = 15 miles
15 miles is your answer.

Complelment adds to 90
let's say the complement is B
A+B=90
4x+2+B=90
minus (4x+2) from both sides
B=88-4x
