Answer:
65 miles
Step-by-step explanation:
y=55+0.35x
77.75 = 55+0.35x
77.75 - 55 = 0.35x
22.75 = 0.35x
22.75 ÷ 0.35 = 0.35x ÷ 0.35
65 = x
x = 65
Answer:
the answer is 40
Step-by-step explanation:
x+60
x=60-20
x=20
Its simply helps you visualizing what part is negative/positive. For inequations (ex: 3x+9>10), its super important to let you know from where to where the equation is, in my example, higher than 10.
Answer: last option.
Step-by-step explanation:
According to the Product of powers property, you have:
As you can see, when you can add the exponents when you have powers with equal base.
Then, 
and 
do not have the same base, therefore, the exponents can't be added.
Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.
