So we're given Y = 3x.
We now can replace Y, for 3x in the equation:
Y = x + 4
3x = x + 4
3x - x = 4
2x = 4
x = 2
Answer: x= 5
Step-by-step explanation: Distribute the -7 into the parentheses, we get 14x+63=133. You then minus 63 on the left side of the equation and on the right side of the equation. You will get 14x=70. You then solve x by dividing 70 by 14 you will get x=5.
Answer: 5/9 x 2/8. The probability that the first marble is green and the second is red is 13.8%. In fraction form, the answer is 5/9 x 2/8 because the two outcomes must be multiplied. I really hope that helps!
Answer: x= 12 and MNQ= 25 degrees
3x - 11 + 65 = 90
3x + 54 = 90
3x = 36
x = 12
plug in the value of x to get MNQ
3(12) - 11
36 - 11
25
