$27.41-$3.17=$24.24

$24.24/6=$4.04

So $4.04 each candy bar

Answer:

Step-by-step explanation:

Plug in 7 for d:

y= 1/2(7+1)

y=1/2(8) .... Adding what's in the parenthesis (PEMDAS)

y=4 ..... Multiply 1/2 by 8

Hope this helps:)

$700 is invested at 4% per annum. How long will it take for the amount to reach $784?

Blababa [14]

Answer:

3yrs

Step-by-step explanation:

Given parameters:

Capital = $700

Percentage interest = 4% per annum

Unknown:

Time it will take for amount to be = $784

Solution:

To find the simple interest on an amount;

I = $\frac{PRT}{100}$

P is the principal

R is the rate

T is the time

I is the interest

Insert the parameters:

I = $\frac{700x 4 x T}{100}$

I = 28T

So;

At the end of the duration:

Principal + Interest = Amount

700+28T = 784

28T = 784 - 700

28T = 84

T = 3yrs

Consider the function.

dlinn [17]

Answer:

Statement 3

Step-by-step explanation:

y = -2/3x-24

Make x the subject

y + 24 = -(⅔)x

x = -(3/2)(y + 24)

Intersection variables

f^-1(x) = -(3/2)(x + 24)

Slope: -3/2

No domain restrictions

y-intercept: x = 0

-(3/2)(0+24)

-36

(0,-36)

x-intercepts: y = 0

0 = -(3/2)(x + 24)

x = -24

(-24,0)

Linear function, range is all real values of y

Guys, please help me with problem.

likoan [24]

Answer:

$\boxed{\bold{-25}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{\frac{-5^2+10^2}{-2\cdot \:5\cdot \:3+3^3}}$

$\bold{-5^2+10^2: \ 75}$

$\bold{\frac{75}{-2\cdot \:5\cdot \:3+3^3}}$

$\bold{-2\cdot \:5\cdot \:3+3^3: \ -3}$

$\bold{\frac{75}{-3}}$

Apply fraction rule: $\bold{\frac{a}{-b}=-\frac{a}{b}}$

$\bold{-\frac{75}{3}}$

Divide $\bold{\:\frac{75}{3}: \ 25}$

$\bold{-25}$
