Earned Income because she is working full time, but also adds the extra 20$ for when she tutors in her free time<span />
Same thing as what you did on the bottom. Find numbers with both 7 as the base and numbers that add to 14 on the top. Possibilities:
1) 7^10•7^4
2)7^6•7^8
37^2•7^12
Any angle A[anything]B will have measure 90°.
The angle BWD cannot be determined from information shown here.
The answer is 370 because you need to work it out.
Basically what I did was look at the first number, 12, and the answer to the equation and saw that 12 x 10 would be 120. And 360 + 10 would be 370.
It fits in perfectly.
12(370 - 360) = 120
370 - 360 = 10
12(10) = 120
So x = 370
B is the answer, because the half of the balls added
