Answer: 148.5
Step-by-step explanation:
well there is no real question here but cody is 165 which means you have to multiply that by 10% or 0.10 which gives you 16.5 and subtract that from the total
Coefficient = 7 and 1
7 is the coefficient of a
1 is the coefficient of b
X +y=13
1/2*x+y=10 |-1
x +y=13
-1/2*x-y=- 10 } +
x-1/2*x=13-10
1/2*x=3
x=3*2
x=6
6+y=13
y=13-6
y=7
The solution is : (6,7)
The answer for this question is letter B
