Answer:
41hrs
Step-by-step explanation:
$7*35hrs= $245
$308-$245=$63
$63/10.50=6hrs
35+6=41
This is has two real solutions.
If Sheila started with 8 yards of fabric and used 2 1/4 yards, she will have the difference of these two values remaining. Subtract 2 1/4 from 8.
Convert the mixed fraction to an improper fraction. (Multiply its denominator by the whole number and replace the numerator with this new number.)
2 1/4 = 9/4
We now have:
8/1 - 9/4
Multiply 8/1 by 4/4 to get common denominators.
8/1 × 4/4 = 32/4
Now subtract.
32/4 - 9/4 = 23/4 = 5.75
Alternatively, we could have converted the fraction 2 1/4 to decimal form and subtracted it from 8.
2 1/4 = 2.25
8 - 2.25 = 5.75
Answer:
Sheila has 5.75 yards of fabric left.
If x=8 {f(8)=3x+4}, the answer is 28.
Comment the correct answer.
Answer:
50
Step-by-step explanation:
Assuming you're solving for Q, the first step is to multiply the first set of parenthesis by 0.10:
0.10(72-Q) = 7.2 - 0.1Q
The next step is to combine the terms that have Q in them:
7.2 - 0.1Q + 0.25Q = 14.7
7.2 + 0.15Q = 14.7
Now isolate 0.15Q:
0.15Q = 14.7 - 7.2
0.15Q = 7.5
Divide 7.5 by 0.15 to solve for Q:
Q = 7.5/0.15 = 50
