Answer:

The interest is $1350 and the amount is $5850.

Step-by-step explanation:

STEP 1: Find an interest by using the formula I = P*I*T, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

In this example P = $4500, i = 7.5% and t = 4 years, so

4500*0.075*4

I = 1350

STEP 2: Find an amount by using the formula .

Since P = $4500 and I = $1350 we have

$4500 + $1350 = $5850

What is 5(n-1)=2(n-4)-6
Shalnov [3]

Answer:

Step-by-step explanation

6n - 6 = 2 (n+1)

Simplify 2 (n+1)

6n - 6= 2n +2

Move all terms related to n to the left side of the equation

4n -6 =2

Move all terms not related to n to the right side of the equation

4n =8

Divide each term by 4 then simplify

n=2

Write an expression that is equivalent to three over four (5z+ 16).
sattari [20]

Your answer is 15 over four z + 12. Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.

Help me please..... please
Oksana_A [137]

Answer:

general rule Un=1.8n-21

U100=1.8(100)-21=159

Step-by-step explanation:

a5=a+4d,  a5=-12

a10=a+9d,  a10=-3

-12=a+4d

-3=a+9d subtract the system of equations

-9=-5d solve for d

d=1.8

substitute d into first equation to find a

-12=a+4(1.8)

a=-19.2

un. = a + (n − 1)d

Un=-19.2+(n-1)(1.8)

Un=1.8n-21
