The answers are x=4 and y=323/2
1) 40/2x-3=8
Multiply both sides by 2x-3 to get rid of fraction
40= 8(2x-3)
Distribute 8
40= 16x-24
Add 24 to both sides
64=16x
Divide by 16
4=x
2) 2y-3/40=8
Multiply both sides by 40 to red rod of fraction
2y-3=320
Add 3 to both sides
2y= 323
Divide by 2
Y=323/2
Now just describe the differences in solving them
FYI / means fraction, right after the slash is bottom of fraction
Answer:
Arithmetic Sequence

Answer:
kiloliters
Step-by-step explanation:
The amount of water a family uses in a year is a large amount of water - more than the amount of water in a pool! This means kiloliters would be the best unit of measurement.
Answer:
{x +4} {x+3} =0
Step-by-step explanation:
The equation is given as :
x² + 7x + 12 =0
Find multiples of 12 that can add to give +12 ------3 * 4
The equation can then be written as;
x² + 3x + 4x + 12 = 0 ------factorize
x{ x + 3 } + 4 { x +3 } = 0
{x+4 } {x + 3} = 0
Answer : {x +4} {x+3} =0
