Answer:

<em>Hence, the equation is:</em>

$-3x-7=-28$

<em>and the solution is:</em>

$3x=28-7\\\\3x=21\\\\x=7$

Step-by-step explanation:

A two step equation is a equation that takes just two steps to solve.

Now we have to formulate a two-step equation that involves multiplication and subtraction, includes a negative coefficient, and has a solution of x=7.

negative coefficient means that the coefficient of the variable term must be negative.

so, we take a equation as:

$-3x-7=-28$

Clearly the coefficient of variable term is: -3 which is negative.

Now we solve the equation as:

$3x=28-7\\\\3x=21\\\\x=7$

Hence, the equation is:

$-3x-7=-28$

The savings account offering which of these APRs and compounding periods

Ann [662]

Answer:

The answer is "Option C"

Step-by-step explanation:

The using formula $= (1+\frac{r}{n})^n -1$

→r = rate

→ n = compounded value

In choice a:

When compounded is monthly $4.0784\%$

$n = 12$

$\to (1+ \frac{0.040784}{12})^{12} = 1.0403-1 = 0.0403$

In choice b:

When compounded is quarterly $4.0792\%$

$n = 3\\\\\to (1+ \frac{0.040792}{12} )^{3} = 1.0102-1 = .0102$

In choice c:

Whenn compounded is daily $4.0730 \%$

$n = 365\\\\\to (1+ \frac{0.040730}{12})^{365} = 3.328-1 = 2.328$

In choice d:

When compounded is semiannually $4.0798\%$

$n = 2\\\\\to (1+ \frac{0.040798}{12})^{2} = 1.0066-1 = 0.0066$

If the parallelogram floor needs a base of 16 feet,what will the height of the floor be

nydimaria [60]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete because the area of the parallelogram is missing. However, the following will guide you in answering the question</em>

Given

$Base = 16\ ft$

Required

Determine the Height

Area of a Parallelogram is:

$Area = Base * Height$

Make Height the subject

$Height = \frac{Area}{Base}$

Substitute 16 for Base

$Height = \frac{Area}{16}$

This implies that you divide the value of area by 16 to get the height of the parallelogram.

Take for instance;

$Area = 64ft\²$

The height would be

$Height = \frac{64}{16}$

$Height = 4\ ft$

Or

$Area = 80ft\²$

The height would be

$Height = \frac{80}{16}$

$Height = 5\ ft$
