1.20 x 18=21.6 Therefore 3/7 is equal to $21.6. So 21.6/3= 7.2 which is equal to 1/7. If 7.2 is 1/7 that means that 7.2 x 7 which is 50.4 is your answer. So she had $50 and 40 cents. PLEASE MARK BRAINLIEST ANSWER :)
True. Both methods correctly verify the trig identity
Answer:
Below
Step-by-step explanation:
● 3 ( -x +2x - 1) = x - 1
● 3 ( -x -1 ) = x - 1
● -3x -3 = x - 1
Add -x to both sides
● -3x -3 - x = x -1 -x
● -4x -3 = -1
Add 3 to both sides
● -4x - 3 + 3 = -1 + 3
● -4x = 2
Divide both sides by -4
● -4x/-4 = 2/-4
● x = -1/2
Answer:
(5,14)
Step-by-step explanation:
4x+6=2x-4
2x=10
x=5
y=2x+4
y=2(5)+4
y=14
(3+a+2) (a+2-3)
(5+a) (a-1)
5a-5+a^2-a
Rearrange and combine like terms
a^2 +4a-5
