20-13=7, 21-12=9, 7*9=63; 20*12=240; ANSWER: 63+240=303
Answer:
x=1
Step-by-step explanation:
8x-1=3x+4
8x-1+1=3x+4+1 *You add one on both sides
8x=3x+5
8x-3x=3x-3x+5 *Then you subtract 3x by positive 3x and subtract 8x by -3x
5x=5
5x/5=5/5 *Divide both sides by 5
x=1 *An finally you get your answer
Okay to solve this you need to divide the volume to the two measurements
728 ÷ 8 = 91 ÷ 6.5 = 14
