Answer:
7 hours
Step-by-step explanation:
We have that the value of the review of a bicycle has the following function:
v = 14 + 9 * t
where t is the time in hours
if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:
77 = 14 + 9 * t
solving for t:
t = (77 - 14) / 9
t = 7
that is to say that Sara left the bicycle in a total of 7 hours
Answer:
she could get 80s
she could get 5a
Step-by-step explanation:
s- 4 songs per dollar
4x24=80
a- 5 albums per $20
5x5= 20
Answer:
Vertical angles are supplementary angles
Step-by-step explanation:
when the lines intersect perpendicularly. For example, ∠W and ∠ Y are vertical angles which are also supplementary angles. Complementary angles are two angles with a sum of 90º. Supplementary angles are two angles with a sum of 180º. Vertical angles are two angles whose sides form two pairs of opposite rays.
Answer:
Step-by-step explanation:
Alright let's get it!
(WHOOP! WHOOP! WHOOP! WHOOP!)
First let's start with:
How can the difference of squares be written?
a^2 − b^2
This will be our friend for a while!!!
STEP 1:
Now let's start with the first problem:
t^2 − 1
It can be rewritten as,
t^2 − 1^2
Therefore choice 1 works!
STEP 2:
Next one:
p^2 − 40
The number 40 is not a complete square of any number, therefore choice 2 is not correct.
STEP 3:
Almost there!
n^2 − 225
It can be rewritten as,
n^2 − (15)^2
It is the difference of squares, therefore choice 3 is correct!!!
STEP 4:
Last one!!!!!
k^2 + 81
It can be written as,
k^2 + 9^2
It is the sum of squares, therefore the last choice is incorrect.
So......
The correct ones are:
Yassss, we survived!
So happy we got to do this together!
Hope this helps!!!
