The answer is 3.45 (C) because 1.15 x 3 = 3.45
Answer:
x = 3, and y = 2
Step-by-step explanation:
2x + 3y = 12 -------- (1)
y = x - 1 ---------------(2)
Substitute value of Y in (2) in (1)
2x + 3(x-1) = 12
2x + 3x - 3 = 12
5x - 3 = 12
5x = 12 + 3
5x = 15
x = 15/5
x = 3
Put the value of x in equation 2
y = x-1
y = 3 - 1
y = 2
Therefore, x = 3, and y = 2

Answer:
x =150 men
Step-by-step explanation:
Think of the total as workdays
125men* 120days = 15000 workdays
We still need 15000 workdays
100 days * x = 15000workdays
Divide by 100
x = 15000/ 100
x =150 men
