1. 35x + 0.15y
=3500x + 15y [multiplying the equation by 100]
= 700x + 3y [dividing the equation by 5]
2. Let x be an even integer
x + (x+2) + (x+2+2)
x+x+2+x+4
3x+6
3. 1/5*(r+7) - 9s
(r+7)/5 - 9s
4. x=cows
y= goats + sheep
x= (y+140)/2
Answer choice D. is a repeating decimal

Step-by-step explanation:
Answer:
From the calculation it is clear that ratio of paint use by Gina is not same as that of teacher .
Step-by-step explanation:
Given as :
The quantity of yellow paint mix by teacher = 9 pints
The quantity of blue paint mix by teacher = 6 pints
The quantity of yellow paint mix by Gina = 4 pints
The quantity of blue paint mix by Gina = 3 pints
Let The ratio of yellow to blue paint by teacher = x : y
i.e x : y = 9 : 6
or, x : y = 3 : 2
So, The ratio of yellow to blue paint by teacher = 3 : 2
<u>Again</u>
The ratio of yellow to blue paint by Gina = a : b
i.e a : b = 4 : 3
or, a : b = 4 : 3
The ratio of yellow to blue paint by Gina = 4 : 3
Hence, from the calculation it is clear that ratio of paint use by Gina is not same as that of teacher . Answer
