Answer:
Step-by-step explanation:
The triangles CED and CGF are similar since two sides are on same line and one side is parallel.
<u>Corresponding sides have equal ratios:</u>
- CG/CE = CF/CD
- CG/CE = (CD - 1.8)/CD
- 6/(6 + 2.4) = (CD - 1.8)/CD
- 6/8.4 = (CD - 1.8)/CD
- 1/1.4 = (CD - 1.8)/CD
- 1*CD = 1.4CD - 1.4*1.8
- 0.4CD = 2.52
- CD = 2.52/0.4
- CD = 6.3
Answer:
Step-by-step explanation:
Let the price is x.
<u>Set the equation and solve for x:</u>
- (x + 5%) + 15 = 141
- 1.05x + 15 = 141
- 1.05x = 126
- x = 126/1.05
- x = 120
Rearranging y + 15 = 3x we have
3x - y = 15
so its none of them
Answer: I got C) 12 . . . . .
Answer:
x=3 y = 4
Step-by-step explanation:
3x+5y=29 .........*2 (multiply by2) = 6x+10y=58
2x+3y=18 *-3 = (multiply by -3)= -6x-9y = -54
ADD both(-6x cancels 6x) y= 4
2x+ 3y = 18 2x+ 12 = 18 2x = 6 x = 3
