Answer:
30 times
Step-by-step explanation:
Jeanna : Haylee = 2 : 5
The number of times Haylee babysits in one month is unknown, so it is represented as x.
Write a new ratio to represent the scenario
2 : 5 = 12 : x
Ratios can be written as fractions
Rewrite
2/5 = 12/x
Cross multiply (numerator * denominator / numerator * denominator)
2x = 60
x = 30
Haylee babysat 30 times that month
Hope this helps :)
<span>the answer is subtraction</span>
Add them 2 equations to eliminate x's
-2x-y=9
<u>2x-9y=1 +</u>
0x-10y=10
-10y=10
divide by -10
y=-1
sub back
-2x-y=9
-2x-(-1)=9
-2x+1=9
-2x=8
divide by -2
x=-4
y=-1
(x,y)
(-4,-1)
