You can choose to answer this with fractions or decimals. I'll choose fractions because we won't need calculators. 22 1/2 miles "in" 1/3 hour, means 22 1/2 mi divided by 1/3 hour.
22 1/2 = [(22×2) + 1] ÷ 2 = 45/2
So (45/2)mi ÷ (1/3)hr is the same as (45/2) × (3/1), or (45×3)/2 = 135/2, which is 67 1/2, or 67.5 mi/hr (mph).

Answer:
Many expressions would satisfy this set. One example would be y = 7x + 2
Step-by-step explanation:
To find this, give x a random coefficient, for this purpose, we'll use 7.
y = 7x + c
Now plug in and solve to get the constant.
-33 = 7(-5) + c
-33 = -35 + c
2 = c
Now model the equation.
y = 7x + 2
Hello!
You can put x into the answer choices to see if we get y
----------------------------------------------------------------------------------------------------
y = -x + 9
y = -(-5) + 9
y = 5 + 9
y = 14
This could be a answer
y = -(-2) + 9
y = 2 + 9
y = 11
y = -(1) + 9
y = -1 + 9
y = 8
y = -(4) + 9
y = -4 + 9
y = 5
we got y every time so the answer is the first one
The answer is A) y = -x + 9
Hope this helps!
