Answer:
-6
Step-by-step explanation:
8x/3 - 2x/4 = -13
find the L.C.M
<u>32x - 6x </u> = -13
12
<u>26x </u> = -13
12
cross multiply
26x = -156
divide both sides by 26
26x/26 = -156/26
x = -6

Answer:
1. 180
2. 300
3. 480
Step-by-step explanation:
1. Since 30% of 600 (or 0.3 * 600) = 180, the 1st blank is 180.
2. 50% of 600 (also easy to just think of one half {1/2}) = 300
3. Because 180 + 300 = 480
