Answer:
25
Step-by-step explanation:
5(n-8)=3n+10
5n-40=3n+10
5n=3n+50
2n=50
n=25
20 minutes on passing .....40 minutes on shooting
ratio of time spent on shooting to passing....
these are not hard, u just have to pay attention to the wording...
the ratio of shooting to passing is 40/20 which reduces to 2/1 or 2:1 or
2 to 1 <===
but if it would have asked for passing to shooting, it would have been :
20/40 which reduces to 1/2 or 1:2 or 1 to 2
so ur answer is 2/1 or 2:1 or 2 to 1
Answer:
My answer is 1170 but the way I figured out the problem was by listing numbers 1-30. the problem state that the 1st row had 10, 2nd row had 12, and 3rd row had 14 and so forth. So I basically did the same method till I got to 30 and then add up all the numbers which gave me the answer of 1170.

Answer:
D) Multiply A by -4 and B by 5
Step-by-step explanation:
5x-2y=10
4x+3y=7
----------------
-4(5x-2y)=-4(10)
5(4x+3y)=5(7)
----------------------
-20x+8y=-40
20x+15y=35
---------------------
23y=-5
y=-5/23
5x-2(-5/23)=10
5x+10/23=10
5x=10-10/23
5x=230/23-10/23
5x=220/23
x=(220/23)/5
x=(220/23)(1/5)
x=220/115
x=44/23
