GIVEN:

  • <u>Scale factor</u> :- 5/2

ANSWER:

Perimeter of ΔDEF = 5.5 + 2 × 7

  • 5.5 + 14
  • 19.5cm

So, perimeter of ΔJKL = 19.5 × 5/2

  • 97.5/2
  • 48.75

Half the marbles in a bag are red, 1/6 of the marbles are blue, and the remaining 8 marbles are white how many total marbles are
Gemiola [76]

Hey there! I'm happy to help!

Let's represent the total number of marbles with the variable t. We have the following information.

1/2t+1/6t+8=t (1/2 of total are red, 1/6 of total are blue, 8 are white, add them up to get total)

Now, we solve for t.

1/2t+1/6t+8=t

We combine like terms.

2/3t+8=t

We subtract t from both sides.

-1/3t+8=0

We subtract 8 from both sides.

-1/3t=-8

We divide both sides by -1/3.

t=24

Therefore, there ae 24 total marbles in the bag.

Have a wonderful day! :D
