Answer:
$128.49
Step-by-step explanation:
4 gallons at $15.72 each is 4×$15.72 = $62.88
3 gallons at $21.87 each is 3×$21.87 = $65.61
The total purchase is ...
$62.88 +65.61 = $128.49
Tim will be spending $128.49 on paint.
You have to add the same kind of terms, in this case the ones that have a variable (5.4q and -4.5q) and the ones that don't (2.4 and 3.6), like this:
(5.4q - 4.5q) + (2.4 + 3.6) = 0.9q + 6
The answer is c. 0.9 +6
step.1 turn both of the numbers into fraction
24x8=192, because 8 out of 8 is 1. Plus one equals to 193/8
1x2=2 plus 1 equals to 3. 3/2
step.2 turn the bottom numver the same
because 2x4 is 8 from the bottom
3x4 is 12 so the lemonade she sampled is 12/8
step.3 substract
193/8-12/8you keep the bottom the same substract the top.
193-12
the answer is : 181/8
Answer:
D. Up
Step-by-step explanation:
When a parabola has the form 
, It is vertical (opens up or down).
Because the variable "x" is squared.
If "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.
In this case you have the quadratic function:
Which can be rewritten as:
Therefore, it is vertical, because it has the form:
You can observe that the value of "a" is:
Then, since "a" is positive, the parabola opens up.
Be more specific on the first one
