Answer: combine
Step-by-step explanation:
When you combine like terms, it shortens or simplified the equation
Example: 2x-5+15
Combine actual numbers -5 and 15.
2x+10
1 pound = 16 ounces
16+9 = 25 ounces
2 /25 = 0.08 per ounce
it costs 8 cents per ounce
Answer:
- 18x - 9 = 72
- 3(6x - 3) = 72
- x = 45
Step-by-step explanation:
Apply the distributed property:
- Apply the distributed property: 3/5 × 30x = 18x, 3/5 × 15 = 9
- Re-write the equation: 18x - 9 = 72
- 18x - 9 = 72 is an option listed, so that's one of the answers.
See the other options:
- Another option that looks like it could be the answer is 3(6x - 3) = 72
- Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
- This is the same as what we got above, so it is also an answer.
Solve:
- Add 9 to each side, so it now looks like this: 18x = 81
- Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
- x = 45 is an option listed, so that's one of the answers.
I hope this helps!
Answer: x=-2
Step-by-step explanation:
To solve for x, we want to isolate x.
-4(11x+2)=80 [distribute]
-44x-8=80 [add both sides by 8]
-44x=88 [divide both sides by -44]
x=-2
Now, we know that x=-2.
Answer:
- Both are terminating decimals
Step-by-step explanation:
<u>Answer to your questions:</u>
- First of all, both A and B are correct and both quotients are terminating decimals.
- To find out if the decimal is terminating or not, multiply the quotient by divisor. If you get exactly the same number as dividend, then it is terminating otherwise it is non-terminating.
- The fraction may have greater numerator than denominator, in this case the quotient will be greater than one.
- Now regarding simplification. You would be asked to give an answer rounded to some extend. One decimal place, two decimal places, 3 significant numbers etc. For the first operation you would get 34.8 (rounded to nearest tenth).
- Or you may be asked to have a best estimated result. In this case you would round the initial numbers and find results. 205/714 ≈ 0.29
