Answer:
10 7/12 hours
Step-by-step explanation:
so we have to multiply 2 2/3 twice since he does that many hours for 2 days. We then have to multiply 1 3/4 three times since he does that many hours for 3 days. Lets first convert 2 2/3 into a mixed fraction. 2 2/3 = 3 times 2 =6 +2=8 over 3. 1 3/4=4 times 1=4+3=7 over 4. 8/3 times 2 equals 16/3 which eqials
5 1/3 hours. 7/4 times 3 equals to 21/4 which equals to 5 1/4. Lets now add
5 1/3 and 5 1/4. 5+5=10 but the fractions are not the same. Therefore, we need to make it to a common denominator. 4 times 3 equals to 12 so 4/12 plus 3/12 equals 7/12. Final answer equals to 10 7/12.
After you solve for both sides x=90

Answer:
Step-by-step explanation:
= n^2 + (3n^2 + 3n + 1 / n-3) = 3n
= BTW (/ = Fraction) and ^ means exponent
= n^2 + 3n + (12n + 1 / n - 3) = 12
= 37 / n - 3
Answer: n^2 + 3n + 12 +( 37 / n - 3)
Hope this helps :D
Answer:
18
Step-by-step explanation:
Evaluate g(2), then substitute the value obtained into f(x)
g(2) = 2² - 1 = 4 - 1 = 3 , then
f(3) = 2(3)² = 2(9) = 18
