Answer:
222 miles.
Step-by-step explanation:
<u>Lets create an equation to solve this easier.</u>
<u>Let x represent the miles driven in the truck. </u>
Our equation is 238.51=.98x+20.95
All we have to do now is solve for x.
Subtract 20.95 on both sides.
217.56=.98x
Now divide both sides by .98 to isolate the variable.
222=x

Answer: x² - x - 12
Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.
<em>First, Outer, Inner, Last</em>.
We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.
So we have x² - 4x + 3x - 12.
Simplifying from here by combing the middle terms, we have x² - x - 12.
Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.
Answer:
x = 3
y = -2
Step-by-step explanation:
x - 2y = 7
y = -x + 1
x - 2y = 7
x - 2 ( -x + 1 ) = 7
3x - 2 = 7
3x = 9
x = 3
y = -x + 1
y = -3 + 1
y = -2
