B. is reasonable because 9.2×4.8 = 44.16
Answer:
185 minutes.
Step-by-step explanation:
It is possible to model an equation for this, such that
where x represents the number of minutes.
Then, you solve for x:
Answer:
$45
Step-by-step explanation:
(25*1)+(4*5)=
25+20=
45
Answer:
(-2, 5)
Step-by-step explanation:
I will assume that your system is
y = -4x - 3
y = -2x + 1
Multiplying the second equation by -2 results in
y = -4x - 3
-2y = 4x - 2
combining these two equations eliminates x temporarily:
-y = -5, so that y must be 5.
Substituting 5 for y in the second equation, we get:
5 = -2x + 1, or
4 = -2x, which results in x = -2
and so the solution is (-2, 5)
Assuming you can’t use the same topping twice,
10 x 9 x 8 = 720
