1. (3x-2)/4+1=5
2. (3x-2)/4+1-1=5-1
3. (3x-2)/4=4
4. (3x-2)/4+2=4+2
5. this is the mistake, wecan't just add them because the fractions aren't the same
(3x-2)/4 plus 2/1, the bottom numbers areen't the same
what should be done is go back to step 4 and mltiply both sides by 4, don't add 2
results in
5. 3x-2=16
6. 3x=18
7. x=6
Answer:
1. All the ones that start with the word two.
2. 2 2/3
3. 8x6=48
Step-by-step explanation:
Step-by-step explanation:
[(-3 × 2 × (-4)] ÷ [-6 × 12]
[3 × 2 × -4] ÷ [-6 × 12]
[6 × -4]/[-6 × 12]
-4/(-1 × 12]
-4/-12
⅓
Option A is wrong
Option B is wrong -9/-18 = ½ not ⅓
Option C is correct = -24/-72 = ⅓
Option D is wrong = 9/-18 = -½ not ⅓
Answer:
a=11
Step-by-step explanation:
3/a + 5/2a = 1/2
Determine the range
3/a +5/2a = 1/2 , a=0
Write all numerators with common denominators above 2a
11/2a = 1/2
11/2a = 1/2 Simplify the equation using cross-multiplication
22=2a Switch sides of the equation
2a=22 divide both sides of the equation by 2
a=11 is your answer
