Answer:
x is the number of miles
Step-by-step explanation:
Because the per mile charge is $2.65 per mile .. so for x miles, the per mile charge is 2.65x. And the fixed charge is the initial charge of $2.50.
y = 2.50 + 2.65x
1.) Gather all the sides (length, width, and height)
V=l×w×h
2.)Plug in the correct and appropriate volume:
V=8×6×
3.)Multiply all of them:
V=8×6×
=48×
=
=16 (after simplifying)
4.) State the answer in a sentence:<span>
The volume of the rectangular prism is 16 </span>
.
Hope this helps!
Answer:
1 7/8 cups leftover
Step-by-step explanation:
The total amt. of sugar Suze needs is 5(1 1/2 cups) = 15/2 cups, or 7.5 cups.
Combining the 3 1/4 and 6 1/8 cups of sugar remaining in the bag results in 3 2/8 + 6 1/8 cups, or 9 3/8 cups total. She needs only 7.5 cups of this sugar.
Thus, she has leftover the following amount: 9 3/8 - 7 4/8 cups, which
simplifies to 1 7/8 cups
Step-by-step explanation:
well,
(y - 7)² = (y - 7)(y - 7)
remember how to multiply 2 expressions ?
you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).
so, when we do the multiplication, we get
(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =
= y² - 14y + 49
and that is clearly different to y² - 49
FYI
y² - 49 is the result of
(y - 7)(y + 7)
because
y×y + 7×y - 7×y + (-7)(7) = y² - 49
