Answer:

$280

Step-by-step explanation:

Principal = $3,500

Time = 2 Years

Interest Rate = 4%

Interest = Principal x Time x Interest Rate

Interest = $3,500 x 2 x 0.04

Interest = $280

Simplify 1/x-3+4/x divided by 4/x-1/x-3

Alchen [17]

The answer is $\frac{5x-12}{3x-12}$

The expression is: $\frac{ \frac{1}{x-3}+ \frac{4}{x} }{ \frac{4}{x} - \frac{1}{x-3} }$

Let's factorize it:
$\frac{ \frac{1}{x-3}+ \frac{4}{x} }{ \frac{4}{x} - \frac{1}{x-3} } = \frac{ \frac{x*1}{x(x-3)}+ \frac{4*(x-3)}{(x-3)*x}}{ \frac{(x-3)*4}{(x-3)*x}- \frac{x*1}{x*(x-3)}}= \frac{ \frac{x+4(x-3)}{x(x-3)} }{ \frac{4(x-3)-x}{x(x-3)} }$

Since $\frac{ \frac{a}{b} }{ \frac{c}{d} }= \frac{a}{b}/ \frac{c}{d}= \frac{a*d}{b*c}$ , then:
$\frac{ \frac{x+4(x-3)}{x(x-3)} }{ \frac{4(x-3)-x}{x(x-3)} }= \frac{(x+4(x-3))*x(x-3)}{(4(x-3)-x)*x(x-3)}$

Cancel x(x-3) and simplify:
$\frac{(x+4(x-3))*x(x-3)}{(4(x-3)-x)*x(x-3)} = \frac{x+4(x-3)}{4(x-3)-x} = \frac{x+4x-12}{4x-12 -x} = \frac{5x-12}{3x-12}$

I know ask me how...

Lemur [1.5K]

I believe it's 2110. Because you have to multiply the numbers and then add the 2 numbers to get the final number. So 7 times 3 is 21
7 + 3 is 10
So I got 2110.

Help ASAP! <br> Complete the table to practice finding starting values in equations.

Gelneren [198K]

Answer:

1. b = 40

2. b = 3

3. b = 10

Step-by-step explanation:

1. y is 40 more than 5 times x.

Equation: y = 5x + 40

b = 40

2. y is 3 more than twice the value of x.

Equation: y = 2x + 3

b = 3

3. y is 10 more than 6 multiplied by x.

Equation: y = 6x + 10

b = 10

Last week, Josh practiced a song 12 times. If he practiced the song 4 times on his own, how many times did he practice the song

sineoko [7]

Answer:

Hello, it seems my fellow Josh needs some help, so here we go. It's quite simple, the answer is 8.

Step-by-step explanation:

12 - 4 = 8

or 8 + 4 = 12.

So he practiced 8 times in public, or to others.
