Answer:

The first one is -4 and the second one is 12. all you will need to do is change the + to a - then do for the first one which would be -7- -3= -4 so to check it you will need to use the + to check it so it will be -3+-4=-7. and for the second one you will need to do -11- -23=12 so to check it you will need to change the - to + so it will be set up as 12+ -23=-11.

i believe the answer is y = -2x + 6

Answer:

i believe the answer should be y=-2x+6

Step-by-step explanation:

y=-2x+b

plug in -2 for y and 4 for x

-2=-2(4)+b

-2=-8+b

add 8 on both sides

6=b

plug in 6 for b

y=-2x+6

Answer: The second one y=46/13x

Step-by-step explanation:

Answer:

y = 46/13x

Step-by-step explanation:

Answer:

Because for the first problem you would have to simplify 8 divided by 2 into 4  in which  12 - 4 = 8 then you would have to simplify 12 - 4 to 8 which 8 = 8

Because  for the second problem you would have to simplify 12 - 8 to 4 which  4 divided by 2 = 2 then you would have to simplify 4 divided by 2 to 2 which 2 = 2

Answer:

Only Week 1

Step-by-step explanation:

We know that Salesman C only earns $900, no matter how many sales he makes, so we can just ignore his data for the rest of the problem. This also tells us that both Salesmen A and B have to earn less than $900 each week. That being said, let's start with Salesman A;
Now Salesman A makes $65 per sale, with no base salary, and can't go over $1,300. So starting with the first week, we do 11 sale x $65 (per means multiply) which gives us $715. Then you just repeat for weeks 2 and 3, giving us $910 week 2, and $1040 week 3. Since Salesman C made less than Salesman A for both weeks 2 and 3, we now only need to check week 1 for Salesman B.
Salesman B has a base salary of $300, and gets $40 per sale. So that means we have to do (14 sales x $40) + $300= $860. We don't need to check weeks 2 and 3, but if you wanted to, you would get $900 for week 2 and $840 week 3.
Knowing all of this, the only week Salesman C made more than BOTH Salesmen A and B is week 1, since Salesman A made more than Salesman C weeks 2 and 3, and Salesman B made more than Salesman C in week 2.

Answer:

answer 7

Step-by-step explanation:

The solution is 6 parts of red paints

The number of red paints for the color to paint the kitchen is given by the equation A = 6 parts of red paints

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of parts of red paint be represented as A

Now , the equation will be

The number of red paint parts for 6 parts of yellow = 2 parts of red paint

The number of parts of yellow paint = 3 x 6 parts

The number of parts of yellow paint = 18 parts of yellow paint

So ,

The number of parts of red paint for 18 parts of yellow paint A = 3 x number of red paint parts for 6 parts of yellow

Substituting the values in the equation , we get

The number of parts of red paint for 18 parts of yellow paint A = 3 x 2

The number of parts of red paint for 18 parts of yellow paint A = 6 parts

Therefore , the value of A is 6 parts

Hence , the number of parts of red paint is 6 parts

Step-by-step explanation:

The solution is 1.6 cups

The number of cups of sugar needed for 4 batches of cookies is 1.6 cups

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The number of cups of sugar for each batch of cookies = 0.4 cups

The number of cookies in 1 batch = 16 cookies

Now , the number of cookies in 4 batches = 4 x 16

The number of cookies in 4 batches = 64 cookies

Now , the number of cups of sugar for 4 batches A = 4 x number of cups of sugar for each batch of cookies

Substituting the values in the equation , we get

The number of cups of sugar for 4 batches A = 4 x 0.4

The number of cups of sugar for 4 batches A = 1.6 cups of sugar

Therefore , the value of A is 1.6 cups

[tex]12\frac{1}{8}[/tex]

Step-by-step explanation:

First find the LCM so we can get a common denominator. The LCM is 8 in this case.

[tex]6\frac{7}{8}+5\frac{2}{8}[/tex]

Now addthe numerators and the whole numbers. Remeber, the denominator stays the same number, 8.

[tex]11\frac{9}8}[/tex]

Since 9/8 is an improper fraction, we have to make it into a mixed number. The mixed number form is [tex]1\frac{1}{8}[/tex]. Add it to 11 and you get this: [tex]12\frac{1}{8}[/tex]. I hope this helps!

We can use the number line for the pair of points (-4,1) and (-4,7) to find the distance.

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines.

Given that a number line going from negative 2 to positive 8. Points are at 1 and 7.

Remember that the distance between two points (a,b) and (a,c) can be found by calculating the distance between b and c, the second coordinates.

Also, for a pair of points (x,y) and (z,y), we can determine the distance between those two points by calculating the distance between x and z.

Therefore, we need to find pair of point whose form are; (a,b) and (a,c) or (a,b) and (c,b).

In this case of (-4,1) and (-4, 7), and (-4,-1) and (-4,-7).

For the first pair of points, we have the distance between 1 and 7, and, as for the second pair of points, the distance between -1 and -7.

Thus, the answer is (-4,1) and (-4,7).
