Answer:
x = - 1
Step-by-step explanation:
Given
2 = 3x + 5 ( subtract 5 from both sides )
- 3 = 3x ( divide both sides by 3 )
- 1 = x
Answer:
-4
Step-by-step explanation:
Parallel lines have the same slope
If the green line has a slope of -4, then the red line has a slope of -4
X4+(95x2)-500=0
x4+(190)-500=0
x4-310=0
x4=310
x=4√(310)
x=4.196
Answer:
225
Step-by-step explanation:
Mary = 3x (3 times Carey)
Carey = x
Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)
3x + x + x/2 = 405
4x + x/2 = 405
8x/2 + x/2 (treat these as fractions) = 405
9x/2 = 405
9x = 810 (cross multiply)
x = 90
Mary = 3(90) 270
Carey = 90
Barry = 90/2 45
Mary - Barry
270 - 45 = 225
Hope this helps! :)
