Answer:
0r
Step-by-step explanation:
Since they all have r you can pretend it s not there and add it on at the end.
Now 10 - 5 is 5. 5 + 3 is 8. 8 - 8 is 0. tack the r onto the end and you get 0r.
Answer:michelle
Step-by-step explanation: it is 70% of the cost since it’s 30% of the original
40% x 70% will give you the answer in percent.
.4 x .7 = .28 He has a 28/100 chance or 7/25 chance (reduced).
If X is between P and Q, then PQ is the whole line segment and XQ and XP are line segments that add up to PQ. Therefore, you can make an equation where XQ and XP add up to PQ.
XQ + XP = PQ
(3k) + (7k - 2) = 6k + 18
Combine like terms.
10k - 2 = 6k + 18
Add 2 to both sides.
10k = 6k + 20
Subtract 6k from both sides.
4k = 20
Divide both sides by 4.
k = 5
Plug 5 for k into XP.
XP = 7(5) - 2 ⇒ 35 - 2
XP = 33
4x-10=2
add 10 to each side (addition property of equality)
4x-10+10=2+10
simplify
4x = 12
divide by 4 (division property of equality)
4x/4 = 12/4
simplify
x=3
