Answer:
A. Dividing both sides by 4 isolates the variable.
Step-by-step explanation:
In order to solve for x, you need to get it all by itself. Dividing both sides of the equation by 4 gives you 8 on the right side and only x on the left side , therefore the variable is isolated. (This uses the Division Property of Equality.)
Answer: x= -10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4.5(8−x)+36=102−2.5(3x+24)
(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)
36+−4.5x+36=102+−7.5x+−60
(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)
−4.5x+72=−7.5x+42
−4.5x+72=−7.5x+42
Step 2: Add 7.5x to both sides.
−4.5x+72+7.5x=−7.5x+42+7.5x
3x+72=42
Step 3: Subtract 72 from both sides.
3x+72−72=42−72
3x=−30

Hey there!
To find how many rolls were sold in the morning, you must multiply 54, the total amount of rolls, by 1/6, the amount of the whole sold in the morning. This would be represented by this expression:
54*1/6
Now, simplify the expression to find how many rolls were collected in the morning:
54*1/6=54/6
54/6=9
Therefore, 9 rolls were sold in the morning.
Hope this helps and have a marvelous day! :)
Answer:
x ≤ 4
Step-by-step explanation:
Solve the inequality
5x - 18 ≥ 2(4x - 15)
Expand the expression
5x - 18 ≥ 8x - 30
Rearrange the terms
5x - 8x ≥ -30 + 18
Combine like terms
-3x ≥ -30 + 18
Calculate
-3x ≥ -12
Divide both sides
x ≤ -12/-3
Calculate
x ≤ 4

Answer:
=10t-6-7.5t = 6-0.5t
= 2.5t- 6 = 6-0.5t
= 2.5t+0.5t = 6+6
= 3t = 12
= t = 12/3
t = 4
Therefore the answer is 4
