X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
Hello, the answer is H!!
I added a screenshot of what I used to find the answer
so, the repairman charges $45 for each hour of work, and $44 for the parts, now the parts are obtained only once, so that's a one-time charge of 44 bucks, let's see how the hours go.
1 hour of work................... 45 + 44(1)
2 hours of work................45 + 44(2)
3 hours of work................45 + 44(3)
4 hours of work................45 + 44(4)
x hours of work................45 + 44(x)
so the cost equation, with x = hours, C(x) = 45 + 44x.
what is x if C(x) = 179?

Step-by-step explanation:
thats what i got im sorry if its wrong
M₁ = 5.97 * 10²⁴
m₂ = 7.35 * 10²²
r₁ = 0
r₂ = 3.84 * 10⁸
r = distance from earth center to center of mass
r*(m₁+m₂) = r₁m₁ + r₂m₂
r = (r₁m₁ + r₂m₂) / (m₁ + m₂) = (0 + 2.82 * 10³¹) / 6.0435 * 10²⁴ = 4,66 * 10⁶
