Answer:
- (5/22)
Step-by-step explanation:
(12-2x+8)/3 = (6x + 15)/2
(20 - 2x)/3 = ( 6x + 15)/2
Now cross multiplication
40 - 4x = 18x + 45
-18x - 4x = 45- 40
- 22x = 5
x = - ( 5/22)
4:7
3:5=6:10/2=3:5
9:15=9:15/3=3:5
x= 25/3 or 8.333333
you add 11 to 10 to get 21
3x-4=21
add 4 to both sides, which will cancel out the (-4)
3x=25
divide each term by 3 to get x by itself
3x/3 = 25/3
you will then get x=25/3
y=10x+28.75 This is the answer, use slope
= 6 2/3
