40 = 12.99 + 15.49 + x
Total 40, 12.99 and 15.49 is how much he has spent, and x is the variable to be solved for
If this helped pls mark branliest.
Answer:
40-12.99-15.49=11.52
40-(15.49+12.99)=11.52
Step-by-step explanation:
There are two ways you can complete this you can just keep subtracting or you can add the two number that you need to subtract and then subtract them.
The future value of an account in one year with a $450 deposit and a 2.1% annual interest rate is $459.45.
The question asks about the future value of an account with a certain initial deposit and an annual interest rate. The future value can be calculated using the formula for simple interest: FV = P * (1 + r * t) where FV stands for Future Value, P stands for the initial Principle amount, r is the annual interest rate and t stands for time.
Applying this formula for your question, the initial deposit P is $450, the interest rate r is 2.1% or 0.021 (in decimal form), and the time t is 1 year.
So, FV = $450 * (1 + 0.021*1) = $450 * (1.021) = $459.45.
Therefore, the future value in one year for an account that was originally deposited with $450 and has a 2.1% annual interest rate is $459.45.

A. -12(-3/4)
B. -13(3/4)
C. -12- 3/4
D. -12 + 3/4
The expression (3)(4)(-3/4) is equivalent to -9.
None of the given options is correct.
Given information:
The expression is (3) (4) (-3/4).
Multiplying 3, 4, and -3/4, we get:
(3)(4)(-3/4),
Simplify the parenthesis,
= 12(-3/4)
Multiplying,
= -36/4
Divide -36 by 4, and we get,
= -9
Therefore, the expression is equivalent to:-9

Answer:
17
Step-by-step explanation:
There are a total of 39 students.
students.
The number of students that play football is twice as much as the number of students that play volleyball.
Let the number that plays volleyball be x then the number that plays football will be 2x. This we have
x + 2x = 39
3x = 39
x = 13
The total number that plays volleyball is 13.
The total number that plays football will be 2 x 13 = 26
Since 9 students play both sports, the number of students that plays only football will be 26 - 9 = 17.
