Answer:
11
Step-by-step explanation:
2^3-(30/5)+9
First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:
P- parentheses
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
so 30/5 = 6 and plugged in is:
2^3-(6)+9
Next, we do exponents:
2^3 = 2x2x2 = 8
plugged back in:
8-(6)+9
Now, we do the math from left to right so:
8-6=2
2+9=11
11 is your answer
Answer:
1500 dollars
Step-by-step explanation:
annual means yearly and we want to find how much it will cost for 5 months
First thing we want to do is find how much it cost every month and to do that we divide 3600 by 12
3600/12=12 so it cost 300 dollars monthly
then we just multiply that by 5
5x300=1500 so it cost 1500 dollars for 5 months
Answer:
Let us assume that the pay rate per hour = x
no. of hours worked = n
Gross earnings = x*n
Federal taxes = 18% of gross earnings
= 0.18(x*n)
State taxes = 4% of gross earnings
= 0.04(x*n)
Social security deduction = 7.05% of gross earnings
= 0.0705(x*n)
Total deductions = Federal taxes + State taxes +SSD
= 0.18(x*n) + 0.04(x*n) + 0.0705(x*n)
= 0.2905(x*n)
Net pay = Gross earnings - Total Deduction
Net pay = x*n - 0.2905(x*n)
Net pay = 0.7095(x*n)
Solution
For this case we can do the following:
11y - 3x = 18
16y -3x = 33
We can multiply the first equation by -1 and we got:
-11y +3x =-18
16y -3x = 33
_______________
16y -11y = 33-18
5y = 15
y= 15/5 = 3
And then solving for x we got
x = -(18 -11*3)/ 3= -15/3 = 5
