Answer:
A or the 1st one
Step-by-step explanation:
Angelo is making 9 dollars per hour but, loses 2 dollars due to the bus fee. So in math form that would be:
9x - 2
And the second part is Tom makes 8 dollars per hour but doesn't have to pay for bus fee. In math form that would be;
8x
So put that together that would be
9x - 2 = 8x
Answer:
c is the correct anser your welcome.
12
First figure out of it is a arithmetic or geometric sequence, in this case it is a geometric sequence because you have to multiply, not add to find the next number.
Divide one number, I'll pick 324 by the number before it, 108, you get three.
Now divide 36 by 3, you get 12.
To check, multiply 12 by 3, you get 36, multiply that by 3, you get 108, and so on and so forth.
-2x + 6y = -34
-x + 3y = -17
x = 3y +17
Sub this into 1st eqn
5(3y + 17) + 2y = 21
15y + 85 + 2y =21
17y = -64
y = -3.7647 (to 5 sig. fig.)
y = -3.8 (to nearest tenth)
Sub y = -3.7647 into 2nd eqn
x = 3(-3.7647) +17
x = 5.7 (to nearest tenth)
