Answer:
It takes them 7minutes to finish 50env
Step-by-step explanation:
We know that jerry can stuff 7 in 2min and tom can do 4 per min, so 8 for every 2min.
So 8+7=15env for every 2min 7.5/min
15+15=30+15=45
50=15x/2 50*2=15x 100=15x 100/15=x x=6.67 then rounded it to 7min
Answer:
7(2+3x)-3x and 4(3+3x)+2(1+3x)
Step-by-step explanation:
7(2+3x)-3x
= 14 + 21x - 3x
= 18x + 14
2(6x+7)+10x
= 12x + 14 + 10x
= 22x + 14
4(3+3x)+2(1+3x)
= 12 + 12x + 2 + 6x
= 18x + 14
7(2+3x)-3x and 4(3+3x)+2(1+3x) are equal expressions.
