Answer:
8
Step-by-step explanation:
the ratio or fraction for this problem would be 1 (gold coin) : 25 (points)
If we want to find out how many gold coins he needs to get 200 points we need to divide 200 by 25.
200/25 : 8
if we want to check our answer do this
1:25
1 x 8 is 8
25 x 8 is 200
Soo... Collin needs to find 8 coins to win 200 points.
hope i helped
X=-39/5 and y=10 :) i hope this helps you out !
Answer:
12
Step-by-step explanation:
26+(-2)=24
24/2=12
Answer:
The solution would be (5, -2)
Step-by-step explanation:
To use this method, start by multiplying the second equation by -1. Then add the two equations together.
9x + 5y = 35
-2x - 5y = 0
------------------
7x = 35
x = 5
Now that we have the value of x, use it to solve either equation for y.
2x + 5y = 0
2(5) + 5y = 0
10 + 5y = 0
5y = -10
y = -2
We know the perimeter is the total sum of all sides of the shape, we can use this to form an equation: the perimeter=1st side + 2nd side + 3rd side + 4th side 39a-7=9a+(5a+1)+(17a-6)+4th side.
Collect like terms to get 39a-7=31a-5+4th side
If we move everything but the 4th side over to the left we can solve
C. 8a-2=4th side is the correct answer
