I’m having that same problem
Answer:
<u>29</u> $1 bills and <u>14</u> $5 bills.
Step-by-step explanation:
Let 
be the number of $1 bills and 
be the number of $5 bills. With the information given, we can set up two equations:
1) 
2) 
There are two ways to solve it; with elimination or substitution. In this explanation, I will solve it with elimination.
To solve it with elimination, multiply the first equation by 5 to get:
Then, you can subtract the equation we just got by the second equation to get:
Thus, 
. To find y, just substitute x for 29 in the first equation to get:
. Therefore, 
. That means that there are 29 $1 bills and 14 $5 bills. You can check by substituting those values for x and y in either of the first two equations.
Hope this helps :)
The formula for calculating the annual insurance is D. p= 2rb
Answer:
The correct answer is c. c is the square of half of b.
Step-by-step explanation:
In all perfect square trinomials, half of the middle number squared gives you the constant. See the example below for proof.
(x + 4)^2
(x + 4)(x + 4)
x^2 + 4x + 4x + 16
x^2 + 8x + 16
You'll notice if you take the middle term (8), cut it in half (4) and then square it (16), the result is the constant.
Answer:
66
x+6
Step-by-step explanation:
Because you add from the x's then you go on from the hope this helped :) .
