Answer:
5
Step-by-step explanation:
2x +9 =4x - 1
2x - 4x =-1 - 9
-2x=-10 /(-1)
2x=10
x=10 :2
x=5
If the bottom side is ab then bc is <span>8.18535277, which to the nearest tenth is 8.2

6 hundreds, since 10*6=60, and so then 10*6=60 hundreds
Parallel lines have the same slope but different y-intercepts. Start with y=mx+b substitute your point given to you for x and y but leave slope alone. Figure out b.
You should get y=3x-27.
Rachel: 3 bracelets in an hour.
Oliver: 2 bracelets in an hour but has completed 5 bracelets
Rachel : y = 3x
Oliver : y = 2x + 5
Let x be the number of hours. y is the total number of bracelets made in x hours.
3x = 2x + 5
3x - 2x = 5
x = 5
It would take 5 hours for Rachel to have the same number of bracelet as Oliver.
Rachel: 3x = 3(5) = 15
Oliver: 2x + 5 = 2(5) + 5 = 10 + 5 = 15
