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.

Correct Option: [tex]\angle XVW[/tex] and [tex]\angle YVX[/tex] are the same size

Step-by-step explanation:

Two angles are adjacent when they have a common side, a common vertex, and don't overlap.

The image shows the following angles are adjacent:

YVZ and YVX

YVZ and YVW

YVX and XVW

Furthermore, two angles are said to be linear if they are adjacent angles formed by two intersecting lines.

The first, fourth, and fifth options are true as shown above, which discards as true the second option.

The only probable false option is that XVW and YVX are the same size. They certainly could be, but we have to evidence of that, thus this option is considered false.

Correct Option: [tex]\angle XVW[/tex] and [tex]\angle YVX[/tex] are the same size

Answer:

x = 3/7

Step-by-step explanation:

Red paint : White paint = 3 cups : 7 cups

How many cups of red paint should be added to 1 cup of white paint

Red paint : White paint = x cups : 1 cup

Equate the ratios

3 cups : 7 cups = x cups : 1 cup

3 / 7 = x / 1

Cross product

3 * 1 = 7 * x

3 = 7x

Divide both sides by 7

x = 3 / 7

Number of cups of cups of red paint that should be added to 1 cup of white paint is 3/7

I did this by representing the unknown number of cups of red paint with x and equating the two ratios

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:

mark above answer Brilliantly

thats correct

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: [tex]a_{n}=653+(n-1)608[/tex]

Step-by-step explanation: This sequence of numbers is an arithmetic progression: a sequence of numbers in which the last number is the previous number plus a constant factor.

For example, the sequence:

653 1261 1869 2477 3085 3693

if you subtract each term with its previous number, the result will be 608:

1261 - 653 = 608

1869 - 1261 = 608

...

33693 - 3085 = 608

For a general arithmetic progression, the nth value is

[tex]a_{n}=a_{0}+(n-1)r[/tex]

where

[tex]a_{n}[/tex] is the wanted value

[tex]a_{0}[/tex] is the first value

n is number of terms or values

r is constant factor

For the sequence above, nth value is:

[tex]a_{n}=653+(n-1)608[/tex]

The algebraic expression for the nth value in this sequence is [tex]a_{n}=653+(n-1)608[/tex].

Step-by-step explanation:

Answer:

The equation is y = 2/3x - 1

Step-by-step explanation:

To build the equation, we know the slope is -2/3, so that is done for us already. Now we just need the y-intercept, which is -1, which is the only way to get it to cross the point (-9, 5). So, the equation would be y = 2/3x - 1, while still meeting all of the qualifications. I hope this helps, and I hope it's not right, but I do not think it is.
