Answer:
She wont think it is perfect
Step-by-step explanation:
The ratio of Ari's perfect ice cream is
333 caramel : 555 scoops
Freeze zone ratio is
666:888
Not proportional because you multiply 333 x 2 to get 666, but when you multiply 555 x 2 you wont get 888.

Answer:
The vehicle covers 126 miles on 7 gallons of fuel.
Step-by-step explanation:
Given:
The distance traveled is directly proportional to the amount of fuel.
For 
gallons of fuel distance traveled 
miles can be given as:
∝
where 
is constant of proportionality.
The vehicle covers 
miles on 
gallons.
So
Dividing both sides by 5.
∴ 
When 
gallons
miles
∴ The vehicle covers 126 miles on 7 gallons of fuel.
Using linear combination method to solve the system of equations 3x - 8y = 7 and x + 2y = -7 is (x, y) = (-3, -2)
<h3><u>
Solution:</u></h3>
Given that, a system of equations are:
3x – 8y = 7 ⇒ (1) and x + 2y = - 7 ⇒ (2)
We have to solve the system of equations using linear combination method and find their solution.
Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated. Addition or subtraction can be used to perform a linear combination.
Now, let us multiply equation (2) with 4 so that y coefficients will be equal numerically.
4x + 8y = -28 ⇒ (3)
Now, add (1) and (3)
3x – 8y = 7
4x + 8y = - 28
----------------
7x + 0 = - 21
7x = -21
x = - 3
Now, substitute "x" value in (2)
(2) ⇒ -3 + 2y = - 7
2y = 3 – 7
2y = - 4
y = -2
Hence, the solution for the given two system of equations is (-3, -2)
