Answer:

3.9x+0.8y

Step-by-step explanation:

4x−5.2y+6y+7.9x−8x

Combine −5.2y and 6y to get 0.8y.

4x+0.8y+7.9x−8x

Combine 4x and 7.9x to get 11.9x.

11.9x+0.8y−8x

Combine 11.9x and −8x to get 3.9x.

3.9x+0.8y

It can also be converted to fraction form:

[tex]\frac{4y}{5}+\frac{39x}{10} = 3.9x+0.8y[/tex]

AY = 4.8YD = 2.4

Step-by-step explanation:

Corresponding sides of the triangles are ...

ΔFUN . . . ΔDAY

UF = 10 . . . AD = 6

FN = 4 . . . DY

NU = 8 . . . YA

Corresponding sides are proportional, so we have ...

DY/4 = AD/UF = 6/10

DY = 4(0.6) = 2.4

and

YA/8 = 6/10

YA = 8(0.6) = 4.8

The side lengths are ...

AY = 4.8, YD = 2.4

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compounded monthly for 5 years.

Answers

Answer:

$367.17

Step-by-step explanation:

we are find the cost of the car after 5 years

Using the compound interest formula;

A = P(1+r/n)^nt

Given

Principal P = $300

rate r = 5.2% = 0.052

Time t = 5years

Time of compounding n = 1/12 (monthly)

Substitute into the formula

A = 300(1+0.052(12))^5(1/12)

A = 300(1+0.624)^0.4167

A = 300(1.624)^0.4167

A = 300(1.2239)

A = 367.17

hence the amount of the car after 5years is $367.17
