Step-by-step explanation:
Answer:
A = C + 16
Step-by-step explanation:
Given
A = B + 12 and B = C + 4, then substitute B = C+ 4 into A, that is

Answer:
true for all x
Step-by-step explanation:
3x - 4 ≤ 2
Add 4 to each side
3x - 4+4 ≤ 2+4
3x<6
Divide by 3
3x/3 <6/3
x<2
or
2x + 11 ≥ -1
Subtract 11 from each side
2x + 11-11 ≥ -1-11
2x≥ -12
Divide by 2
2x/2 ≥ -12/2
x ≥ -6
x<2 or x ≥ -6
true for all x
To determine tax, I like to use this method...
1. Make the percent into a decimal
For exmaple, the pretty high tax of 8% would be 0.08, since you need to move the decimal two places to the left regardless.
2. Multiply
For this word problem, multiply 0.08 and 750, or in other words, multiply the original price by the percent/decimal. 0.08×750=60
3. <em>Subtract the tax from the original price if needed</em><em>!</em>
This example only wants the tax, so this step if not needed, but if it were, subtract 60 from 750 to get a total price of $690.
Answer:
Add 5 to remove the negative 5 from the left side.
Step-by-step explanation:
