A company sells crushed rock in 16-pound bags, each bag contains a mixture or quartz and marbles. The incomplete table below lists the amounts of quartz and marble needed to fill a certain number of bags.

BAGS OF ROCK

1) There are 3 bags with 27 lbs of Quartz and 21 lbs of Marble
2) There are 8 bags with ? lbs of Quartz and 56 lbs of Marble
3) There are ? bags with 99 lbs of Quartz and ? lbs of Marble
4) There are 14 bags with ? lbs of Quartz and 98 lbs of Marble
5) There are ? bags with 135 lbs of Quartz and ? of Marble

1) Marco mixes 135 pounds of quartz with some marbles. If the ratio stays the same for very bag, how many pounds of marble will Marco need?

2) And how many bags will the mixture fill?

false

step-by-step explanation:

i looked it up

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .

you divide them and then you get the answer i took this class this year
