Order of Operations are PEMDAS. So, based on that, the answers would be:
1. 150. Do 20*5 first, as it's in parentheses, then multiply by 10.
2. 36. Same thing as #1 but different numbers.
3. 51. Do the stuff in parentheses first, then multiply because it gets priority over subtraction and then subtract.
4. 16. Do the multiplication in the parentheses first, then the subtraction, and then the division.
-3x-6=2x-1
5x=-5
x=-1
y=-3(-1)-6
y=3-6
y=-3
hope this helps!
Answer:
It will take them roughly 7.27 mintues
Step-by-step explanation:
To find this, model the amount of apples that can collect a minute using m as the minutes.
Isaac = 3m
Juanita = 5m/2
Now we can add them together and solve for when they will have 40 apples.
3m + 5m/2 = 40
5.5m = 40
m = 7.27
