Answer:
5min
Step-by-step explanation:
First form yourself an equation, 113.2-10.8x ≤70
Now begin to work it out
*113.2-10.8(1) ≤70 (instead of x, put a number, this will be how many minutes
1~ 102.4 is not less than or equal to 70, so we repeat this process
2~ 91.9
3~81.1
4~70.3 this is not the answer because even though its at 70 there is still a .3 so we keep going,
5~59.5
59.5 is ≤ 70, so the answer is 5 minutes
P.S. don't believe me? that's okay, use the formula, plug in five to see for yourself
i hope this helps ;)
Answer:
-4 and 4
Step-by-step explanation:
Answer:
72 in. squared
Step-by-step explanation:
12 times 6 = 72
Goal: solve for y. First step: Multiply out 5(y+2) and also 4(2y-1):
5y + 10 and 8y - 4
Then your original <span>5(y+2) = 13+ 4(2y-1)
becomes 5y + 10 = 13 + 8y - 4
Combining the y terms: </span>10 = 13 + 3y - 4
Simplifying the right side: 10 = 3y + 9
Subtracting 9 from both sides: 1 = 3y. Solving for y: y = 1/3
