A bag contains 10 marbles: 4 are green, 2 are red, and 4 are blue. Yolanda chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that the first marble is blue and the second is green? Write your answer as a fraction in simplest form.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

i rlly forgot my bad

step 1: simplify both sides of the equation.

23x − 19x + 5 = 20

23x + − 19x + 5 = 20

(23x + − 19x) + (5) = 20 (combine like terms)

4x + 5 =20

4x+5=20

step 2:

step 2: subtract 5 from both sides.

4x + 5 − 5 = 20 − 5

4x = 15

step 3: divide both sides by 4.

answer: x =

in decimal form: 3.75
