Answer:

x=16.75 y=4.5

Step-by-step explanation:

first turn the first trapezoid sideways so the side that says 8 matches with the side that says 10. This is the proportion. 8:10. The bottom of the first trapezoid says x+2. This matches with the side that says 15. Because the side that says 15 is on the bigger trapezoid, multiply by ten. Then multiply the other trapezoid by 8. We get an equation that looks like. 8x+16=150 Simplify and 8x=134 divide and we get x=16.75. Do the same for the side with y. 8y-24=50. 8y=36 y=4.5. There you have it.

What is the answer to 3x+5y=1; -6x-10y=14

creativ13 [48]

y= -3/5x + 1/5

Explanation: First subtract

3x from both sides, and you should have 5y = −3 x +1

. You are almost there to slope-intercept form, the 5y needs to be just

y. Divide by 5 on both sides (Make sure you divide −3x AND 1 by 5!).

Please help me :) once again

grigory [225]

Answer:

About 11.31 cm

Step-by-step explanation:

If one of the legs of a right iscosceles triangle is 8, then the length of the other one must also be 8. Therefore, by the Pythagorean Theorem:

$h=\sqrt{8^2+8^2}=\sqrt{64+64}=\sqrt{128}\approx11.31$

Hope this helps!

Contruct 3 equation starting with -2

olga_2 [115]

Answer:

1. -2, 2. -23, 3. 25

Step-by-step explanation:

1. -2+5x8/-12= step 1: add -2+5

-2+5=3 step 2: 3(8)

3x8= 24 step 3: 24/-12

24/-12= -2

2. -2(9-4)+3=? step 1: combine like terms -2(9) and -2(-4)

-18-8+3=? step 2: combine like terms

-26+3=? step 3: combine like terms

-23=?

3. 2x + 130=180 step 1: -130 on both sides

2x = 50 step 2: /2 on both sides

x = 25
