Answer:
Explained below.
Step-by-step explanation:
Complementary angles are angles that sum up to 90°.
Here,
Then,
Angle P + Angle Q = 90°
2x + 7x = 90°
9x = 90°
x = 90/9
x = 10°
Therefore,
- Measurement of Angle P = 2x = 2*10 = 20°
- Measurement of Angle Q = 7x = 7*10 = 70°
Answer:
$421.10
Step-by-step explanation:
If the discount is 10%, that means the sale price is 90% of the original price.
Write the equation that represents that:
378.99 = 0.9x. Solve for x. Divide both sides by 0.9
378.99/0.9 = 421.10
That is the price before the discount and tax.
23245 + 21.50b = 46389 + 10.50b
21.50b - 10.50b = 46389 - 23245
11b = 23144
b = 23144/11
b = 2104 <== the cost will be the same at 2104 books
