To find how many miles he went in 1 hour, divide 62.3 by 3.5.
62.3 / 3.5 = 17.8
Answer:the length 7
Step-by-step explanation:each one is times 3 6x3 8x3 3x7=21
For example, if we use 5+3=8.
If you change it to 3+5, it still equals 8.
Therefore, 3+5=5+3 because at the end, they both have equal value aka both end up with 8 using the same numbers. (goes by the rule a+b=b+a)
Answer:
(2x +30) and (3x -5) (they're opposite to eachother, so they're equal)
2x + 30 = 3x - 5 (set them equal to eachother, then subtract 3x from both side)
-1x = -35 (divide both sides by -1 to isolate x)
x = 35 or B (this is your answer)
Step-by-step explanation:
I hope this helps :))
Combine like terms so you end up with 10x+2y
