Answer:
a is 39
b is 57
Step-by-step explanation:
you were given two different expressions to substitute.
the first one is p = 8 and d = 1/7
so we substitute into 5p - 7d
that is 5(8) - 7(1/7)
we get 40 - 1
which if we go ahead to evaluate we get 39
The second one p = 3 and d = -6
so we get 5(3) - 7(-6)
we get 15 - (-42)
if we go ahead to evaluate we get 15 + 42
two negative meeting each other gives you positive.
then it going too be 57
1. Between 2 and 3
2. Between 4 and 5
3.Between 5 and 6
4.Between 6 and 7
5. Between 5 and 6
6.Between 7 and 8.
7. The approximate length of each side is 8.36 cm(square root of 70 will get you this)
Answer:
B
Step-by-step explanation:
First step is to do whatever is in the parentheses: 9-3.
Then you will multiply 7 by that number; which will give you the answer.
B is correct because it does it that way.

Answer: a
Infinitely many
Step-by-step explanation:
Solve by substitution:
1) Solve 
for 
:
2) Substitute 
for in 
:
3) Simplify both sides of the equation:
4) Add -2 to both sides of the equation:
5) Simplify both sides of the equation:
Therefore, there are infinitely many solutions.
Solve by elimination:
You cannot solve this system by elimination
Solve by graphing:
The 
equations are on top of each other, therefore, the system of equations has infinitely many solutions.
