Given : Andre drove 200 Miles using 9 Gallons of Gas
⇒ Andre drives 1 Mile using ![[\frac{9}{200}]\;Gallons\;of\;Gas](https://tex.z-dn.net/?f=%5B%5Cfrac%7B9%7D%7B200%7D%5D%5C%3BGallons%5C%3Bof%5C%3BGas)
⇒ Andre drives (420 × 1 Mile) using ![[\frac{420\times9}{200}]\;Gallons\;of\;Gas](https://tex.z-dn.net/?f=%5B%5Cfrac%7B420%5Ctimes9%7D%7B200%7D%5D%5C%3BGallons%5C%3Bof%5C%3BGas)
⇒ Andre drives 420 Miles using 18.9 Gallons of Gas
Answer:
x = -1, y = 1
Step-by-step explanation:
2x-y=-3 // y = 2x + 3 (eqn 1)
3x+y=-2 (eqn 2)
sub 1 into 2
3x + 2x + 3 = -2
5x = -5
x = -1
sub x = -1 into eqn 1
y = -2+3
y = 1
Answer:
D.3
Step-by-step explanation:
We are going to use the Slope Formula --> (y2-y1)/(x2-x1)
(9-3)/(3-1)=6/2=3
Answer:
there is no picture there
Cary's age is 9 years MORE than Dan's age.
Cary's age is Dan's age, but with 9 more years added to that.
Here is how we can express that,

In 7 years, Cary will be C+7 years old,
and Dan will be D+7 years old.
In 7 years, the sum of their ages,
(C+7) and (D+7) will equal 93.
Here is how we can express that:

You have a system of two equations involving two unknowns. You have a couple of nice options here. You can apply substitution or elimination to complete the problem.
