Answer:
1/2, 2/4
Step-by-step explanation:
4/8 = (2/4) =1/2 (if you divide up and down by the same number)
so 4/8 = 1/2
next, let's simplify the choices we have: (1/5) (2/6) (1/4) (1/2) (2/4)
1/5 is already simplified
2/6 = 1/3
1/4 is already simplified
1/2 is already simplified
2/4 = 1/2
Which of these is equal to 4/8 (aka 1/2)?
Answer: 1/2 and 2/4
Answer:
B) 9
Step-by-step explanation:
Because there's a square between the 2 angles, that means these angles are complementary (angles that add up to 90°). So:
5x - 9 + 6x = 90
11x - 9 = 90
11x = 90 + 9
11x = 99
x = 9

Answer:
A - $2240
Step-by-step explanation:
120(12) + 800 =
1440 + 800 = 2240
Step-by-step explanation:
Work: (A)
a) 20−4x=12−x+8−3x
20−4x=12−x+8−3x
20+−4x=12+−x+8+−3x
−4x+20=(−x+−3x)+(12+8)
−4x+20=−4x+20
−4x+20=−4x+20
−4x+20+4x=−4x+20+4x
20=20
20−20=20−20
0=0
In this equation... All real #s are solutions.
Work: (B)
b) 5x+4x−3=24+8x
5x+4x−3=24+8x
5x+4x+−3=24+8x
(5x+4x)+(−3)=8x+24
9x+−3=8x+24
9x−3=8x+24
9x−3−8x=8x+24−8x
x−3=24
x−3+3=24+3
x=27
Work: (C)
c) 5x+6=2x+6+3x−15
5x+6=2x+6+3x−15
5x+6=2x+6+3x+−15
5x+6=(2x+3x)+(6+−15)
5x+6=5x+−9
5x+6=5x−9
5x+6−5x=5x−9−5x
6=−9
6−6=−9−6
0=−15
