hi

Step-by-step explanation:

this is too hard for me but i am sure u will get it :D

Well, ( − 4) 2 − 28 = 8 has two solutions because (-4) -w = 8 = ? once determined - 4 would equal 20 + the left over which is 8. This can be solved multiple ways and even backwards.

For the the equation (-4)² - 28 = 8 the solutions are x = 2 and x = -10.

Two or more expressions with an Equal sign is called as Equation.

The equation (-4)² - 28 = 8 has two solutions because when we square -4, we get 16.

When we subtract 28 from 16, we get -12.

But if we add 28 to -12, we get 16 again.

So we have two values of x that satisfy the equation: x = -4 and x = 4.

b. We can solve the equation by adding 28 to both sides:

(-4)² - 28 + 28 = 8 + 28

Simplifying, we get:

(-4)²= 36

Taking the square root of both sides, we get:

-4 = ±6

So the two solutions are:

x = -4 + 6 = 2

x = -4 - 6 = -10

Therefore, the solutions to the equation (-4)² - 28 = 8 are x = 2 and x = -10.

The amount Jim owes in interest if he pays it back in 4 years is $160

From the question, we are to calculate how much Jim owes in interest

Using the simple interest formula,

I = PRT

Where I is the interest

P is the principal

R is the rate

and T is the time

From the given information,

P = $500

R = 8% = 8/100 = 0.08

T = 4 years

Putting the parameters into the formula, we get

I = 500 × 0.08 × 4

I = $160

Hence, the amount Jim owes in interest if he pays it back in 4 years is $160

Answer:

10/6 = 1 and 2/3

Step-by-step explanation:

10 pounds of candy, 6 bags.

that means 10 divided by 6, or 10/6

simplify that 10-6 = 4, 6 can only be subtracted once, so it is 1 and 4/6 or 2/3

2/3 is 0.666666... so add it together and you get 1.66666... or 1 and 2/3

Answer:

Carl buys 132.475 liters of water.

Step-by-step explanation:

Since Carl buys seven 5-gallon jugs of water multiply 7 by 5 to know how many gallons of water Carl bought in total.

7(5) = 35 Gallons

Now that you have the total amount of gallons of water Carl bought you have to convert 35 gallons to liters given that 1 gallon = 3.785 liters by multiplying 35 by 3.785.

35(3.785) = 132.475

So Carl bought 132.475 liters of water.

Though that is the answer based on what is given a gallon is actually equal to 3.78541 liters so the exact answer would be 132.489 liters of water.

Answer:

0.555km p/h

shown as 555m  p/h

Step-by-step explanation:

First we convert km to meters

6k = 6000m

Time = distance / rate.

20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr

then 3.33 / 6 = 0.555 km  = 555 meters p/h

Answer:

[tex] \displaystyle m = \frac{2}{3} n + 4[/tex]

Step-by-step explanation:

we are given a equation

we want to make n the independent variable

to do so

move -2n to right hand side and change its sign:

[tex] \displaystyle 3m = 12 + 2n[/tex]

divide both sides by 3:

[tex] \displaystyle m = \frac{12 + 2n}{3} [/tex]

further simplification is needed:

[tex] \displaystyle m = \frac{12 }{3} + \frac{2n}{3} [/tex]

[tex] \displaystyle m = \frac{2}{3} n + 4[/tex]

now m depends on n and n can be any value so we have rearranged n to independent variable

and we are done!
