Answer:
$150.5
Step-by-step explanation:
CP of an item = $140
sales tax rate = 7.5%
sales tax amount = sales tax rate of CP
=7.5% of CP
= 7.5/100 * $140
=$1050/100
=$10.5
total cost with tax = CP + tax rate
=$140 + $10.5
=$150.5
Answer:
The measure of the third angle = 103°
Step-by-step explanation:
The sum of all the angles in any triangle is 180°. Given the two angles of 50° and 27°, we can set up an equation to find the measure of the third angle:
Equation: 50 + 27 + x = 180
Combine like terms: 77 + x = 180
Inverse operations: 77 + x - 77 = 180 - 77
Solve: x = 103°
Answer:
-12
Step-by-step explanation:
x = 12-3a
When a=8:
x = 12-3(8)
x = 12 - 24
x = -12
