We know that, the sum of measures of supplementary angles is 180°
So, the Correct choice is :
because, 65° + 115° = 180°
Answer:
Step-by-step explanation:
3.25 * 0.40 = 1.30
$3.25 + $1.30 = $4.55
The markup price is $4.55
A.
Use PEMDAS
to get rid of the 3/4, divide both sides by 3/4 (.75) and 30 becomes 40
12x + 4 = 40
Subtract 4 from each side to cancel the - 4
12x = 36
Divide both sides by 12 to get rid of the 12
X = 3
Answer:
1. y = 18
2. x = 5
3. y = 2
Step-by-step explanation:
Rule: y = 2x
y = 2 ( 9 )
y = 18
10 = 2x
x = 5
y = 2 ( 1 )
y = 2
