Answer:
There will be 916 ants alive after 4 months.
Step-by-step explanation:
Step 1
Let's change the percentage to a decimal by dividing by a 100.
6.5% / 100 = .065
Step 2
So, for the first month we will multiply the initial amount of ants by .065 and this will give us the number of ants that die.
1200 * .065 = 78
This means that after the first month, 1200 - 78 = 1122 ants will be alive.
Step 3
Now for the second month: 1122 * .065 = 72.93 (rounded to 73)
1122 - 73 = 1049 ants will be alive
Step 4
For the third month 1049 * .065 = 68.185 (rounded to 68)
1049 - 68 = 981 ants will be alive
Step 5
For the fourth month 981 * .065 = 63.765 (rounded to 64)
981 - 64 = 916 ants will be alive
Hope this helps!
Answer:
The Largest Number is 27.
Step-by-step explanation:
Range = Largest Number - Smallest Number
18 = Largest Number - 9
Rearrange the formula to find the Largest Number:
Largest Number = Range + Smallest Number
Largest Number = 18 + 9
Largest Number = 27
You can check this by putting it into the original formula:
Range = Largest Number - Smallest Number
18 = 27 - 9
I’m the first equation solve for y
5x-y=-5
Subtract 5x from both sides
-y = -5-5x
Multiply both sides by -1
Y = 5+5x
Now plug this in for y in the other equation
3x-6(5+5x) =24
Distribute
3x-30-30x=24
Simplify
-27x-30 = 24
Add 30
-27x = 54
Divide
X = -2
Now plug this in the first equation
Y = 5+5(-2)
Y = 5 -10
Y = -5
So X = -2, Y = -5
