Answer:
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
We can create an equation.
x + 165 = 180
Solve for x.
Subtract 165 from both sides.
x + 165 - 165 = 180 - 165
Simplify the equation.
x = 15
Let's solve your system by substitution.
a=−2;b=−3
Step: Solve a=−2for a:
a=−2
Step: Substitute−2for a in b=−3:
b=−3
b=−3
Answer:
a=−2 and b=−3

Answer:
Final cost = $3070.90
Step-by-step explanation:
First we need to find the discount
Discount = original price * percent off
Discount = 2200 * .15
Discount = 330
Sale price = original price - discount
Sale price = 3200-330
Sale price = 2870
Now we need to calculate tax
Tax = sales price times tax rate
Tax = 2870 * .07
= 200.90
Final price = sales price plus tax
Final price = 2870 + 200.90
3070.90
