-t-3 and 3-t are not the same since t-3 would result in a negative answer since both -t and -3 are negative. While in t-3 t is positive and -3 is negative. it is wrong if its left as t-3 since -t-3=3-t is false.
Answer:
There is a mistake in Step 2. Maya distributed 3(x-10) as 3x+30, which is false. The correct step is: 6x+12 = 3x-30
Then solve for x
The answer is B. Maya made a mistake between Step 1 and Step 2 because she did not correctly distribute 3 to (x-10).
Answer:
$77,380
Step-by-step explanation:
If she gets a 6% raise next year she will make 106% of what she makes this year.
106% is 1.06 as a decimal. Multiply her salary by 1.06 to find out how much she will make next year...
$73,000(1.06) = $77,380
Answer:
<h2>x=(y-105)/7</h2>
Step-by-step explanation:
Given that the total time taken to practice is given by the expression as
y=7(15+x)
Simplifying the expression we have
y=105+7x
Solving for x (that is making x subject of formula we have)
7x=y-105
Divide both sides by 7 we have
x=(y-105)/7
Therefore the expression is
x=(y-105)/7
