Answer:

x=-\frac{2}{3}

Step-by-step explanation:

subtract -3(2x-1)+8=15

          -8    -8

_____________

-3(2x-1)=7

divide

\frac{-3(2x-1)}{-3} =\frac{7}{3}

then simplify

2x-1=\frac{7}{3}

add both sides

2x-1+1=\frac{7}{3}+1

simplify again

2x-1+1=\frac{7}{3}+1=2x=-\frac{4}{3}

divide by 2

2x=-\frac{4}{3}

-2    -2

_________

2x÷2=1

-\frac{4}{6}divided by 2

x=-\frac{2}{3}

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags?​
Marta_Voda [28]

Answer:

1020 raisins

Step-by-step explanation:

Let's set up a proportion using the following setup:

raisins/bags= raisins/ bags

We know there are 680 raisins in 8 bags.

680 raisins/8 bags= raisins/bags

We don't know how many raisins are in 12 bags, so we can say x raisins are in 12 bags.

680 raisins/ 8 bags= x raisins / 12 bags

680/8=x/12

We want to find x. To do this, we must get x by itself.

x is being diveded by 12. The inverse of division is multiplication. Multiply both sides of the equation by 12.

12*(680/8)= (x/12)*12

12*680/8=x

12*85=x

1020=x

x= 1020 raisins

There are 1020 raisins in 12 bags.
