Answer:

Let M is the midpoint of DE.

Since D is at 8 and DE = 5.

DM = ME = 5/2 = 2.5

<u>Point M is at:</u>

8 + 2.5 = 10.5 if E is to the right of D
8 - 2.5 = 5.5 if E is to the left of D

<u>Given</u>

XY = 7,
YZ = 2x - 1,
XZ = 30

<u>Since XZ = XY + YZ, set up an equation and solve for x:</u>

7 + (2x - 1) = 30
2x + 6 = 30
2x = 24
x = 12

The distance from your house to friend's is LN.

M is midpoint of LN, so LM = MN
LM = 3x
MN = 2x + 2

<u>Set up an equation, solve for x:</u>

3x = 2x + 2
3x - 2x = 2
x = 2

<u>Find the distance LM:</u>

LM = 3*2 = 6

<u>Find the distance LN:</u>

LN = 2*LM = 2*6 = 12

a bag contains 60 marbles, some blue and some green. the ratio of blue marbles to green ones is 1:5. how many blue marbles are t

olga55 [171]

Hello!

For every 1 blue marble there are 5 greens

You add the numbers in the ratio

1 + 5 = 6

Divide this number from the amount of marbles

60 / 6 = 10

Multiply the ratio by this

1 * 10 = 10

5 * 10 = 50

There are 10 blue marbles and 50 green ones

The answer is 10

Hope this helps!
