Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Angle CAD and angle BAD are congruent.
10x - 7 = 3x+ 7
10x - 3x = 7 + 7
7x = 14
(7x)/7 = 14/7
x = 2
Plug in x as 2.
10(2) - 7
20 - 7
= 13
23.
store price = 14 + 0.5(14)
store price = 21
customer price = 21 + 0.08(21)
customer price = 21 + 1.68
customer price = $22.68
24.
formula: A = P(1 + rt)
A = 140(1 + (0.03)(2))
A = 140(1.06)
A = 148.40
interest = 148.40 = 140
interest = $8.40
Hope this helps!! :)
Pythagora: 20^2=(4x)^2+(3x^2)
400=16x^2+9x^2
x^2=400/25
x^2=16
x=4
