Answer:
The number of solutions is one
Step-by-step explanation:
Here, we want to get the number of solutions
since the linear equations are not the same, neither do they have the same x-variable, we can have only one solution
Answer:
b
Step-by-step explanation:
700x.10=630
630x.05=31.5
630-31.5=598.50
Answer:

Step-by-step explanation:
Remove the parentheses and take out the constansts.

Simplify 7 x 3 to 21.

Use the product rule: 

Simplify 2+5 to 7.

Simplfiy 3 + 8 to 11.

60 5/6 + 56 1/6 = 117
59 1/3 + 54 1/3 = 113 2/3
117 + 113 2/3 = 230 2/3 feet
(6,-7)
This is because if the midpoint to one endpoint goes right 1 and up 5, then the other endpoint will be left 1 and down 5
