What is the value of x?
°x=32
°x=36
°x=37
°x=40

x= 40

Step-by-step explanation:

x + 4x -20=180

5x -20=180

    +20   +20

5x= 200

x= 40

A) x=32

Step-by-step explanation:

To work out the value of x you would first need to minus 20° from 180°, this gives you 160°. This is because the total angle in a straight line is 180° and that by subtracting 20 from 180 you are isolating the value of the x's.

The next step is to add up the number of x's in that angle. You can do this by adding the values of 4 and 1, this gives you 5.

The final step is to divide the angle 160 by the total number of x's of 5, this gives you 32°. This si because we had previously isolated the value of the 5x and so by dividing it by 5 so we would work out the value of x.

1) Minus 20 from 180.

2) Add 4 and 1.

3) Divide 160 by 5.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

i think it is 70
