Answer:
x = 22
Step-by-step explanation:
(x+1)+(3x+1) = 4x+2
4x+2=90°
Solve for x:
4 x + 2 = 90
Subtract 2 from both sides:
4 x + (2 - 2) = 90 - 2
2 - 2 = 0:
4 x = 90 - 2
90 - 2 = 88:
4 x = 88
Divide both sides of 4 x = 88 by 4:
(4 x)/4 = 88/4
4/4 = 1:
x = 88/4
The gcd of 88 and 4 is 4, so 88/4 = (4×22)/(4×1) = 4/4×22 = 22:
Answer: x = 22
Answer:
$26.32
step-by-step explanation:
it originally was $40.00
she has a coupon for 30%
30% of 40.00 is 12
40 • 0.30 = 12
40 - 12
$28
it is now $28 after the coupon
her state charges an 6% sales tax on the discounted price
6% of 28 is 1.68
28 • 0.06 = 1.68
28 - 1.68 = 26.32
