Answer: x=-3

Step-by-step explanation:

First you add 3x+5x cause they are both variables.They equal 8x.

Then you subtract 7x from both sides to get x+17=10

then you subtract 17 from both sides.

you will get x= -3

Hope that helps!

- 7

Step-by-step explanation:

3x + 17 + 5x = 7x + 10

or, 3x + 5x - 7x = 10 - 17 ( take all the variables in one side and all the constants in another side)

or, 8x - 7x = -7

or, x = -7

you can check the answer by putting x = -7 into the equation. after putting the value of x if the Right hand side and left hand side of the equation become same, then your answer is correct.

if not, you need to check the steps again.

Please help this is due today at 2pm Thanks!
Alja [10]

The formula for simple interest is:

A = P(1+rt)

Where P = amount borrowed

r = interest rate

t = time of loan

A = 5000(1 + 0.125*2)

A =6,250

The total amount she paid back was $6,250

For her monthly payment divide total paid back by 24 months ( 2 years = 24 months)

6250 / 24 = 260.42

Her monthly payment was $260.42

Cosxsinx-2cosx=0<br> I dont know how to solve this
jekas [21]
Factor out cosx: cosx(sinx-2)=0
cosx=0 or sinx-2=0
cosx=0 or sinx=2
the largest value of sinx is 1, sinx will never be 2, so cosx=0, x=π/2 or 3π/2 are the two answers.
