Answer:

C.) x = -5

Step-by-step explanation:

-4x = 20

x = -5

-4(-5) = 20

Answer:

C) x=-5

Step-by-step explanation:

-4x=20

divide both sides by -4.....

-4x÷-4=20÷-4

x=-5

Answer:  max capacity is 1625 gallons.

Diagram is shown below.

=========================================================

Explanation:

We'll draw two horizontal number lines to help make a comparison or connection between percentages and tank capacity.

For the top number line, make 5 sections with the labels: 0%, 20%, 40%, 60%, 100%. The reason I'm picking 5 is because 40% = 40/100 = 2/5. So having 40% capacity means we're 2/5 full. That denominator 5 tells us how to subdivide each number line.

The bottom number line will also have 5 sections. We only know one label for this bottom portion right now. That label is 650. Place this directly under the "40%". This visually is one way to represent that 650 gallons is 40% filled. See the diagram below.

Cut the 650 in half to get 325. This corresponds to 40% cut in half to get 20%. Therefore, 325 will go under the 20%. Being 20% full means we have 325 gallons of water.

To figure out the 60% portion, we will multiply 325 by 3. This is because 3*20% = 60%, so 3*325 = 975. We'll write "975 gallons" under the "60%"

Then we have 1300 gallons under the 80% since 4*325 = 1300. Note how 4*20% = 80%, so that's where the '4' multiplier comes from.

Finally, we multiply 325 by 5 to get 1625 and that represents the full tank's capacity. Technically we could have just jumped to this directly without having to find the 60% or 80% capacity values, but it's good practice I think.

Again the diagram is shown below. The answer we're after is at the very bottom right corner. It's under the 100% to indicate the tank is completely full, or has reached max capacity.

-----------------------

Here's a way to find the answer without a double number line. This method involves setting up a proportion.

(40% full)/(650 gallons) = (100% full)/(x gallons)

40/650 = 100/x

40x = 650*100

40x = 65000

x = 65000/40

x = 1625

We confirm that the tank's max capacity is 1625 gallons.

Answer:

9

Step-by-step explanation:

-Twice means muliply by 2

-The difference of a number and 7 means subtract a number/variable and 7.

-Is equal to 9 means =9

2(X - 7) = 9

An equation to model the number is: n - 7 x 2 = 2

To find the equation, break apart the question.

twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2

twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.

twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

Complete question :

Jelena has a piece of fabric in the shape of a parallelogram the height is 10 feet and its base is 16 feet because the fabric into four equal parallelograms by current base and the height in half what is the area of each new parallelogram?

Answer:

40 ft²

Step-by-step explanation:

Given that:

Height = 10 feets

Base = 16 feets

Area of parallelogram = height * base

Area of parallelogram = 10 * 16 = 160 ft²

Area of each new parallelogram :

Area of parallelogram / number of divisions

= 160ft² / 4

= 40 ft²

Answer:

-6,4

Step-by-step explanation:

-6 times 4 is -24. -6 plus 4 is -2

Answer: -6 & 4

Step-by-step explanation:

First, we start by adding the two integers together

-6+4=-2

Then we are going to multiply the two integers together

-6x4=-24

Answer:

$52,488

Step-by-step explanation:

The computation of the commission for the year is as follows:

It is given that  a 13.5% commission is to be paid for each page that he sold

Here the page sold for $1,350

And, he sold average of 24 pages a month

So his commission for the year is

= $1,350 × 24 × 12 × 13.5%

= $52,488

Answer:

Rise -5 and Run 2

Slope of -5/2

Answer:

Step-by-step explanation:

c(f) = [tex]\frac{5}{9}(f-32)[/tex]

[tex]-21 = \frac{5}{9}(f-32)[/tex]

Multiply both sides by 9

-21*9 = 5(f - 32)

-189 = 5*f - 5*32

-189 = 5f - 160

Add 160 to both sides

-189 + 160 = 5f

-29  = 5f

Divide both sides by 5

-29/5 = f

f = -5.8

f = -6 °C

Answer:

x = 11

Step-by-step explanation:

33 divided by 3 is 11, and 11 times 3 is 33.

answer:

11

step-by-step explanation:

the easiest way to explain this is just to divide

33/3

which gets you the answer of 11

but here is another way to explain this

3x = 33

since the 3 and the x are times/multiplying each other and we need to get x by its self, all we do is move the 3 to the other side ( where 33 is ) but instead of multiplying them, we have the change the sign to dividing

3x = 33

/3 ----|>

( dont forgot to rewrite the equation!! )

x = 33/3

now all we need to do is divide 33 by 3 which gives us the answer of

11

Answer:

f(x)-5 = g(x)

Step-by-step explanation:

We translate the function g(x) down 5 units from the function f(x)

g(x) = f(x) -5

Rewriting

f(x)-5 = g(x)

Answer:

Option A

Step-by-step explanation:

f(x) and g(x) are exponential functions

We can see that f(x) is shifted 5 units down

So change in y

hence 5 is to be subtracted

Answer:

-2x + y = -3

Step-by-step explanation:

Find the slope:

9 - 5 / 6 - 4 = 4/2 = 2

Put it in point-slope form:

y - 5 = 2(x - 4)

rearrange:

y - 5 = 2x - 8

y - 2x = -3

-2x + y = -3
