Answer:

Step-by-step explanation:

x/2  - 7 = 9                  Add 7 to both sides

      +7     7

x/2 = 16                        Multiply both sides by 2

2*x/2 = 16*2        

x = 32

You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.

Take a much simpler question

x - 8 = 10        What do you do here? You can't multiply or divide. So add

  +8    8

x    =    18

Now try what you have

2x - 5 = 11                      Add before multiplication or division

    5      5

2x = 16                          Divide by 2

2x/2 = 16/2

x = 8

Answer:

(0, 1 )

Step-by-step explanation:

The y- intercept is where the line crosses the y- axis

On the y- axis the x- coordinate of any point is zero

From the table when x = 0 , y = 1

Then y- intercept is (0, 1 )

Answer:

A is right that is my abswer

Answer:

i think the answer might be opinion C

Answer:

134,000-X=Y

Step-by-step explanation:

you'll first have to solve how many categories there are, but since we don't know we'll use X, we already know that there is 134,000 books, but we don't know how many books are reference or other, so we use Y to represent that.

so it's

134,000-X=Y

Answer:

-2√5

Step-by-step explanation:

First simplify what's inside the radical: 100/5=20

Now we have -√20

The square root of 20 is 2√5 (because 5*4=20 and the square root of 4 is 2)

Because there is a negative the answer has to be -2√5

Here we want to see if the statement:

"A proper use of units can help us to determine the meaning of the slope of a linear function" is true or false.

We will see that it is true.

First, a general linear equation can be written as:

y = a*x + b

Where a is the slope, x is the independent variable, y is the dependent variable, and b is the y-intercept.

The proper use of units is:

y and b must have the same units.

x can have any type of units

The slope must have the quotient between the units of y and the units of x.

Where the proper use of units means that we have the same units on both sides of the expression.

Now, assume that we know the units of y and x.

For example:

y is miles  (then b is also in miles)

x is in hours

Then, with the proper use of units, we can see that the units of the slope are:

miles/hour, or miles per hour.

With this (only knowing the units of x and y) we can see that the slope will be a speed.

So yes, the proper use of units is really important, as this has a lot of information (particularly, the meaning of the slope in a linear equation)

Thus, the statement is true.

Answer:

2 9/10 pans

Step-by-step explanation:

4 2/5-1 1/2=2 9/10 pans

2 and 9/10 pans of lasagna were eaten at the party.

To find out how much lasagna was eaten at the party, you need to calculate the difference between the initial amount of lasagna Margie had and the amount she has left after the party.

Initial amount of lasagna = 4 2/5 pans

Amount left after the party = 1 1/2 pans

First, we need to convert both fractions to a common denominator. The common denominator of 5 and 2 is 10.

Initial amount of lasagna = 4 x 10/10 + 2/5 x 10/10

= 40/10 + 4/10

= 44/10 pans

Amount left after the party = 1 x 10/10 + 1/2 x 10/10

= 10/10 + 5/10

= 15/10 pans

Now, subtract the amount left after the party from the initial amount to find out how much lasagna was eaten:

Amount eaten = Initial amount - Amount left

Amount eaten = 44/10 - 15/10 = 29/10 pans

You can simplify the fraction further:

Amount eaten = 2 + 9/10 pans

So, 2 and 9/10 pans of lasagna were eaten at the party.

Step-by-step explanation:

We are to find how many sandwiches can be made and the ingredients that has leftovers

You can make 20 sandwiches

lettuce has 1 leftover and tomato has unlimited leftover

Recipe for Sandwiches:

Bread = 2 slices

Mustard = 2 teaspoons

Salami = 3 slices

cheese = 2 slices

Lettuce = 2 leaves

Tomato = 1 slice

= 192 teaspoons

= 45 leaves

Recipe available:

Bread = 40 slices

Mustard = 192 teaspoons

Salami = 60 slices

cheese = 48 slices

Lettuce = 45 leaves

Tomato = unlimited

Bread

Recipe available / original recipe

= 40 slices / 2 slices

= 20 servings

No leftovers

Mustard

Recipe available / original recipe

= 192/2

= 96 servings

No leftovers

Salami

Recipe available / original recipe

= 60 / 3

= 20 serving

No leftovers

Cheese

Recipe available / original recipe

= 48/2

= 24 servings

Lettuce = 45/2

= 24 remaining 1

leftover = 1

Tomato = unlimited leftovers

The ingredients available can only make 20 sandwiches equally

Answer:

-6

Explanation:

x= -1 and y=3

3x- y

=> 3(-1)-3 = -3-3= -6

Answer:

3x – y = -6

Step-by-step explanation:

To solve on the problem above, you can do it by substitution and elimination of the two equations.

3x + 2y = 3

➡️ 3x + 2.3 = 3

➡️ 3x + 6 = 3

➡️ 3x = -3

➡️ x = -1

➡️ 3x – y = 3(-1) – 3

➡️ = -3 – 3 = -6 ✅
