A. B. C or D? ​

Answer: 60 miles

Step-by-step explanation: You multiply 3 by 20 because 1 inch is 20

Answer:

The cities are actually 60 miles apart.

Step-by-step explanation:

Take the scale factor 1 inch = 20 miles and multiply it by the number of inches given.

3 × 1 inch  and  3 × 20 miles   3 × 20 = 60

3 inches represents 60 miles

Answer:

width = 17 meters

length = 28 meters

Step-by-step explanation:

Since we are told that the length is equal to 6 less than twice the width, and we know that the perimeter of a rectangle is calculated by adding all the sides together, then we can create the following formula to calculate both the length (l) and width (w).

l = 2w-6

l + l + w + w = 90 ... substitute l with its formula

(2w-6) + (2w-6) + w + w = 90 ... combine like terms

6w - 12 = 90 ... add 12 on both sides

6w = 102 ... divide both sides by 6

w = 17 meters

Now that we know the width we can plug it into the length formula and solve for the length

l = 2w - 6

l = 2(17) - 6

l = 34 - 6

l = 28 meters

Answer:

3x-28

Step-by-step explanation:

"The difference" means subtract.

"Three times" means multiply by three.

"A number" means use any variable (I prefer x).

The mathematical expression for the given situation is 3x-28.

The given statement is "The difference between three times a number and 28".

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

Steps to convert word problem into expression:

Let the unknown number be x.

According to the question, the expression is 3x-28

Answer:

Step-by-step explanation:

For all Plato users.

c = 1.89p and c/p = 1.89 these two equation shows the proportional relationship between the cost c, and price p.

Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.

Here, Total cost = $c

         Price per gallon = $ 1.89

Total cost = Price per gallon X total units

c = 1.89 X p

c = 1.89p

or, c/p = 1.89

Thus, c = 1.89p and c/p = 1.89 these two equation shows the proportional relationship between the cost c, and price p.

Answer:

144 servings

Step-by-step explanation:

1 gallon = 16 cups

2 gallons = 32 cups

3 gallons = 48 cups

Using ratio

4 cups of milk : 12 servings

48 cups of milk : x servings

4 : 12 = 48 : x

4 / 12 = 48 / x

Cross product

4 * x = 12 * 48

4x = 576

x = 576 / 4

= 144

x = 144 servings

3 gallons of milk = 48 cups of milk = 144 servings

Answer:

Company B will charge less to move her items

Step-by-step explanation:

A. Expression that represents the rate each company charges

Let x = number of pounds moved

Company A = 230 + 3.40x

Company B = 270 + 2.80x

B. If Sheila has a total of 1,250 pounds of household items

Substitute x = 1,250

Company A = 230 + 3.40x

= 230 + 3.40(1,250)

= 230 + 4,250

= 4,480

Company A = $4,480

Company B = 270 + 2.80x

= 270 + 2.80(1,250)

= 270 + 3,500

= 3,770

Company B = $3,770

Company B will charge less to move her items

Complete question :

The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item. Expression A: 0.2p Expression B: 0.8p Expression C:1 - 0.2p Expression D: p - 0.2p Expression E: p - 0.8p Which two expressions each represent the sale price of the item?

Answer:

Expression B: 0.8p ;

Expression D: p - 0.2p

Step-by-step explanation:

Given that:

Regular price = p dollars

Discount on price = 20%

Hence,

sale price = regular price - discounted price

Discounted price = 0.2 * p = 0.2p

Sale price = p - 0.2p

Or

Sale price = p - 0.2p = 0.8p

Answer:

y = 3x - 15

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 3) and (x₂, y₂ ) = (5, 0)

m = [tex]\frac{0+3}{5-4}[/tex] = 3 , thus

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (5, 0 ), then

0 = 15 + c ⇒ c = 0 - 15 = - 15

y = 3x - 15 ← equation of line

m3 is 100 degrees

Step-by-step explanation:

In this case, angle 7 is congruent to angle 5 because both their angles are located on the same place in different lines. Another rule you need to know is that angles across from each other are equal. So, if angle 5 is 100 degrees, then angle 3 is also 100 degrees because they are across from each other.
