Answer:

The perimeter of a triangle is the measure of side 1 + measure of side 2 + measure of side 3. To find the perimeter of the triangle, simply add these sides together.

(9x - 7w) + (4x + 6y) + (5y + 5w)

Remove the parenthesis

9x - 7w + 4x + 6y + 5y + 5w

Arrange the order so that like terms are together

9x + 4x +6y + 5y -7w + 5w

Combine like terms

13x + 11y - 2w

Marley runs 5 yards down the track from point A to point B, and then stops and runs

julia-pushkina [17]

Answer:

$\sqrt{61}$ =AC or 7.8102=AC

Step-by-step explanation:

If we connect a line from point A to point C we create a triangle, and we can use pythagorean theorem to find this distance. So the line from point A to point C will be our hypotenuse and the other two distances will be out side lengths.

$5^{2}+6^{2}=AC^{2}$

25+36= $AC^{2}$

61= $AC^{2}$

$\sqrt{61}$ =AC or 7.8102=AC

Jamie is making a beaded necklace the ratio of blue beads to purple beads is 4:3 if jamie uses 56 blue beads and purple beads to

blsea [12.9K]

She will use 42 purple beads.

Explanation
We will use a proportion to solve this.

The ratio of blue to purple beads is 4:3, or 4/3.
We know she uses 56 blue beads and an unknown amount, x, of purple beads. This gives us 56/x.

Together, we have
4/3 = 56/x

Cross multiply:
4*x = 3*56
4x = 168

Divide both sides by 4:
4x/4 = 168/4
x = 42
