Answer:
At least 15 hours
Step-by-step explanation:
First, subtract the $75 that her parents will contribute:
250 - 75
= 175
So, from babysitting, she will have to raise $175
Divide this by 12 to find how many hours she has to babysit:
175/12
= 14.583
We have to round this up to a whole number, which will be 15.
So, Missy will have to babysit for a minimum of 15 hours
Never due to if they have different slopes they can only have 1 solution.

Math is my explanation!
Answer:
System of Equations
3x + 1.5y = 18..... Equation 1
x = 3y ... Equation 2
This is not viable
Step-by-step explanation:
Let us represent
Number of roses = x
Number of camations = y
Juan is buying flowers for his mother. He has $18 to spend and sees that roses are $3 each and camations are $1.50 each.
$3 × x + $1.50 × y = $18
3x + 1.5y = 18..... Equation 1
He wants to buy 3 times as many camations as roses
y = 3x.... Equation 2
Therefore:
System of Equations
3x + 1.5y = 18..... Equation 1
x = 3y ... Equation 2
This is not viable
