Answer:

x = 3, line AB = 17 , and line CD = 17

y = 10, angle A = 70, and angle D = 70

Step-by-step explanation:

well since their the same length you can put them equal to each otheir

5x + 2 = 8x - 7

subtract 5x by both sides to get --> 2 = 3x -7

add 7 to both sides and get --> 9 = 3x

divide 3 by both sides to get x = 3

now plug it back in each equation we started with and get you answers

Same steps for y but different equations

Answer:

See below

Step-by-step explanation:

No actually the top is kinda of wrong. To find the angles I think you do this...

(2y+50) + (3y+40)=180

5y+90=180

5y=90

y=18

Then you plug it in the equations...

tim has 30 jellybeans, with equal numbers of three flavors—raspberry, pineapple, and orange. he likes raspberry the best. so far

Sloan [31]

There are 20 jellybeans remaining after the 6 orange and 4 pineapple jellybeans have been eaten.
Therefore 10 of the 20 remaining jellybeans must be raspberry. So there is a 1 in2 chance that the next one picked will be raspberry.

Anyone know how to solve this??

$Given : \frac{(x^\frac{2}{5})^9\;.\;(x^\frac{-4}{15})}{x^\frac{1}{3}}$

$\implies {(x^\frac{18}{5})\;.\; (x^\frac{-4}{15})}\;.\;(x^\frac{-1}{3})$

$\implies x^(^\frac{18}{5} ^-^\frac{4}{15}^-^\frac{1}{3}^)$

$\implies x^(^(^\frac{54 - 4}{15}^)^-^\frac{1}{3}^) = x^(^(^\frac{50}{15}^)^-^\frac{1}{3}^) = x^(^(^\frac{10}{3}^)^-^\frac{1}{3}^) = x^(^\frac{9}{3}^) = x^3$
