what is 0.75x – 100 ≤ 80

math teacher said its associative

2x + 3y = 26 -- equation 1

3x + 5y =40 -- equation 2

(Equation 1) * 3

6x + 9y = 78 -- equation 3

(Equation 2) * 2

6x + 10y = 80 -- equation 4

(Equation 4) - (Equation 3)

y = 2 -- equation 5

(Equation 5)'s value of y into (Equation 1)

2x + 3(2) = 26

2x = 20

x = 10

Thus x = 10 and y = 2

Hope that helps!

Answer/Step-by-step explanation:

Given;

A store pays $3 for a magazine.

The markup is 5%.

Solve:

$3 × 5% = 0.15      [Markup Price]

$3 + 0.15 = $3.15 [Final Price]

Hence, the total is $3.15.

Answer:

120ft^2

Step-by-step explanation:

because the formula for finding the area of a rectangle is length times width, in this case it is 15 ft for the length and 8 ft for the width, so you would multiply both of those numbers together like 15*8=120ft.

Answer: 6x+3y=12

x=-1/2y+2

Step-by-step explanation:

step 1: add -3y to both sides

6x+3y+-3y=12+-3y

6x=-3y+12

step 2: divide both sides by 6

6x/6=-3y+12/6

Answer:

y = 6 and x = -1.

Step-by-step explanation:

It's normally useful for me to rewrite the equation so they match. I'm using the substitution method.

First find out what "y" equals (I'm using the second equation):

Add 8 to both sides:

y - 8 = 2x

  +8    +8

y = 2x + 8

Plug this into the previous equation.

6x + 3(2x + 8) = 12

Distribute first:

3(2x + 8)

3 * 2x = 6x

3 * 8 = 24

6x + 24

Rewrite the equation:

6x + 6x + 24 = 12

Find liked terms.

6x + 6x + 24 = 12

They are liked terms so combined them: 6x + 6x = 12x.

Rewrite the equation again:

12x + 24 = 12

Solve for "x".

Subtract 24 on both sides.

12x + 24 = 12

      -24   -24

12x = -12

Divide 12 to get x by itself.

12x = -12

    12

x = -1

Plug x into the second equation to find y.

y - 8 = 2(-1)

y - 8 = -2

Add 8 to both sides.

y - 8 = -2

  +8   +8

  y = 6

The answers are y = 6 and x = -1.

Answer:

Step-by-step explanation:

used to hold other items, so it is helpful to know the volume of the box helpful to know the volume of the box.

The volume of the box is V = l × w × h, where l, w, and h are the length, width, and height of the cuboidal box.

A closed three-dimensional geometric shape called a cuboid is surrounded by six rectangular plane sections.

Given a shoe box.

The shape of a shoe box is a cuboid.

Let the length, width, and height of the cuboid be l,w, and h, then the volume of the cuboid is:
V = l × w × h

Hence, the volume of the box is V = l × w × h, where l, w, and h are the length, width, and height of the cuboidal box.

Answer: 3/5

Step-by-step explanation:  

The probability of spinning a one can be written as a fraction. One out of five sections contain a '1' and so, the probability of spinning a one is 1 / 5 . Because 1 is less than half of 5, this outcome can be described as unlikely. The probability of spinning a two is 3 / 5.

22 shirts

Step-by-step explanation:

To find out how many shirts Ms. Li has in total, we have to set up a proportion.

As you can see, we multiply eight by two to get to sixteen. Whatever we do on the numerators, we must do to the denominators. Thus, eleven multiplied by two is twenty-two t-shirts.

Answer:

yes

Step-by-step explanation:

If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:

If she has 6 nickels and 12 quarters:

Number of coins = 12 + 6  = 18

If she has x nickels and y quarters:

Number of coins = x + y  

If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

Answer:

the answer is B on ed2020

Step-by-step explanation:

for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.

so you have soda = 180 cal and juice = 130 cal

if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct

Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories

Let the calories in one serving of milk be x

Let the calories in one serving of juice be y

Let the calories in one serving of soda be z

Thus, for Joe, equation to show amount of calories is;;

2x + y + z = 530    -----(1)

For Darius, equation to show amount of calories is; ;

x + 2y = 370     ------(2)

For Marian, equation to show amount of calories is;

3x + z = 510    ------(3)

Using matrix calculator online to calculate this 3 equations, we have;

x = 110 calories.

Hey there!

Use the slope formula:

[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]

[tex]\bold{\displaystyle\frac{0-0}{5-0} }[/tex]

[tex]\bold{\displaystyle\frac{0}{5} }[/tex]

There's an easier way to determine the slope.

As you can see, the y-coordinates of the points that the line passes through (0, 0) --> the origin and (5, 0).

This means the slope's 0.

Remember that

Hence, the slope's 0.
