Heather purchased a new $1,500 laptop by using a credit card with a 17% interest rate. She will pay off the balance in 2 years by paying monthly payments of $74.16. Calculate Heather’s total cost of repayment.
Answers
12 months in a year
2 years
2x12=24
74.16x24=1779.84
Heather's total cost of repayment is $1,779.84.
What exactly is a monthly payment?A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.
Given,
Principal = $1,500
Rate = 17% per year (or 0.17 as a decimal)
Time = 2 years
Total interest = (principal × rate × time) / 12
Substitute the given values, and we get:
Total interest = (1500 × 0.17 × 2) / 12 = $51
So, Heather will pay a total of $51 in interest over the two years.
Total repayment = monthly payment × number of months
Here,
Monthly payment = $74.16
Number of months = 2 years × 12 months/year = 24 months
Substitute these values, and we get:
Total repayment = $74.16 × 24 = $1,779.84
Therefore, Heather's total cost of repayment is $1,779.84.

Answer:
x = 7x = 4x = 5x = 2Step-by-step explanation:
The general steps are ...
look at what you haverewrite the equation so the variable terms are on one side and the constant terms are on the other side of the equal sign; collect termsdivide by the coefficient of the variableIt is generally convenient to put the variable terms on the side of the equation having the largest (most positive) variable term. You do the rearranging by subtracting the terms you don't want. Any operation is performed on both sides of the equation.
__
1) 3x + 7 = 4x
We observe the largest x-term is on the right, and the only constant term is on the left. We can subtract the x-term 3x to eliminate it from the left side
3x +7 -3x = 4x -3x
Combining like terms gives ...
7 = x . . . . . this is the solution
__
2) x +2 +2x = x + 10
We observe x-terms and constants on both sides of the equation. First of all, we will combine like terms.
3x +2 = x +10
The largest x-term is on the left, so we choose to subtract x (the x-term on the right)
3x -x +2 = x -x +10
2x +2 = 10
We don't want the constant on the left, so we subtract 2.
2x +2 -2 = 10 -2
2x = 8 . . . . . . . . . . combine like terms
Now, we divide by the coefficient of x.
2x/2 = 8/2
x = 4 . . . . . . the solution
__
3) x +3x = x + x + 10
4x = 2x +10 . . . . . . . combine like terms
2x = 10 . . . . . . . . . . . subtract 2x
x = 5 . . . . . . . . . . . . . divide by 2
__
4) 2x +3 + 3x = x + 11
5x +3 = x +11 . . . . . . . . combine like terms
4x +3 = 11 . . . . . . . . . . . subtract x
4x = 8 . . . . . . . . . . . . . . subtract 3
x = 2 . . . . . . . . . . . . . . .divide by 4
_____
Learn to identify and combine like terms. Use addition or subtraction to eliminate terms you don't want. Use multiplication or division to eliminate coefficients you don't want. Whatever you do to one side of the equation must also be done to the other side of the equation. (In the above, we use "subtract ..." to mean "subtract ... from both sides of the equation," for example.)

Step-by-step explanation:
Simply isolate the inequality to get a equivalent inequality. Treat the sign > like an equal sign, what you do to one side, you do to the other side of the inequality.
Isolate the variable, x. Divide 2 from both sides of the equation:
(2x)/2 > (6)/2

help please I have too many points and I also need help on my math
Answers
Answer:
Complementary
x = 55
Step-by-step explanation:
Complementary angles add up to 90°, while supplementary angles add up to 180°.
In this situation, the two angles add up to 90° (the little box means that an angle is a 90° angle) So, the angles are complementary.
Now, we can write this equation.
x + x - 20 = 90
Simplify.
2x - 20 = 90
2x = 110
x = 55
Just in case, let's check the answer.
Substitute x = 55 into (x + x - 20 = 90)
55 + 55 - 20 = 90
110 - 20 = 90
90 = 90
This is true, so x = 55 is correct.

On Friday 1/3 of 180 bottles of water on a supermarket shelf were dold. On Saturday 3/5 of the remainder were sold. All the remaining bottles were sold on Sunday. a) How many bottles were sold on Sunday. b) How many more bottles of water were sold on Saturday than on Friday?
Answers
To find 1/3 of 180, we need to multiply 180 by 1/3, or divide 180 by 3. For this one, we will try both methods.
180/1 x 1/3 = 180/3 or 60
180 / 3 =60
Since we now know how much was sold, we need to find what is left. We need to subtract 180 by 60.
180-60=120
So 120 bottles are left. Now, since 3/5 of 120 were sold the next day, we need to multiply 120 by 3/5.
120/1 x 3/5 = 360/5 or 72.
Now we know that 72 bottles were sold on Saturday. Subtract 120 by 72 to know how much is left in total.
120-72=48
60 bottles of water were sold on Friday.
72 bottles of water were sold on Saturday.
There were 12 more bottles sold on Saturday than Friday.

Denote the Left Denominator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 7
Right_M = L.C.M / R_Deno = n
Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction, multiply the numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 7 • 7

:
When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now, to get rid of the denominator, Tiger multiplies both sides of the equation by the denominator.
Here's how:
49-8n
————— • 7n = 0 • 7n
7n
Now, on the left-hand side, the 7n cancels out the denominator, while, on the right-hand side, zero times anything is still zero.
The equation now takes the shape :
49-8n = 0
Solving a Single Variable Equation:
4.2 Solve : -8n+49 = 0
Subtract 49 from both sides of the equation :
-8n = -49
Multiply both sides of the equation by (-1) : 8n = 49
Divide both sides of the equation by 8:
n = 49/8 = 6.125
One solution was found :
n = 49/8 = 6.125

tan(39) = [tex]\frac{x}{25}[/tex]
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 = [tex]\frac{x}{25}[/tex]
