Answer:
16
Step-by-step explanation:

There are numerous ways to work a problem like this. One is shown above, where we multiply by the inverse of the denominator.
For this you can always use a calculator. Be sure to use parentheses around the denominator fraction.
4m + 90 = ≥ 350
350 - 90 = 260 ÷ 4 = 65
It will take at least 65 minutes for Jeremiah to complete the task.
Replace the variable with 65 to double check.
4 (65) + 90 = 350
Yes for the first and last the middle one should also be x^2+4
To write a fraction as a mixed number, we need to figure out how many times 3 will go into 19. Divide 19 by 3 to get our whole number.
19/3 = 6.
We have 6 0/3 as our mixed number so far, but we have 1/3 left over from the 19/3, since 18/3 = 6.
Add 1/3 to 0/3.
Your answer is 6 1/3.
I hope this helps!
Um i can do these in my calculator if u want
