Answer:
6. D.
7. F.
8. A.
9. B.
10. C.
Step-by-step explanation:
6. 9 + (12 - 10)
12 - 10 = 2
9 + 2 = 11
7. (20 - 15) x 2
20 - 15 = 5
5 x 2 = 10
8. 10 ÷ 5 + 7
10 ÷ 5 = 2
2 + 7 = 9
9. 6 + 2 x 3
2 x 3 = 6
6 + 6 = 12
10. (2 x 4) + 8
2 x 4 = 8
8 + 8 = 16
Let me know if this helps!
Oh my god you have got to be joking.
C IS OBVIOUSLY THE ANSWER
Eight more is + 8, and the quotient of a number and four would be n <span>÷ 4

Answer:
10.7
Step-by-step explanation:
add multiple than subtract what you multiple and add a decimal
The difference is 950 - (-346). The double negative turns into a positive, so it's basically 950 + 346 = 1296 degrees.
Answer:
48.5
Step-by-step explanation:
The constant of proportionality in this case is the speed at which Andrew travels.
We know that the speed is equal to:
v = d / t
We know the distance that is 145.5 miles and the time is 3 hours, replacing:
v = 145.5 / 3
v = 48.5 mi / h
which means that the equation would be:
y = k * x
where k, that is, the constant of proportionality is the velocity 48.5.
y = 48.5 * x
To check if for example x is worth 3, it would be:
y = 48.5 * 3
y = 145.5
