- What is the missing number for this equation? (-3) + _____ = -7
-What is the missing number for this equation ? ______ + (-23) = -11
Answers
2= 12
a negative plus a negative will always be a negative. Think of it as pouring 3 negatives and 4 negatives into a pot. You would just end up with 7 negatives
subtract 23-11 to get 12.
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.

Each batch of cookie mix needs 0.4 cups of sugar, and each batch can make 16 cookies. If Ashley is making 4 batches of cookies, how much sugar does she need?
Answers
Answer:
you will need 1.6 cups of sugar
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
Hence , the number of cups of sugar is 1.6 cups

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

Jordan is painting his kitchen. To get the color he wants, he mixes 2 parts red paint and 6 parts yellow paint.
If he needs 18 parts of yellow paint, how much red paint will he need?
Answers
For every two parts of red there is six parts of yellow. Or you could say for every one part red there are three parts yellow.
This means you would divide 18 by three. That makes six red paint.
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
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 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

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. The following table shows the number of sales each salesman had during the first three weeks of this month.
WEEK 1 2 3
Salesman A 11 14 16
Salesman B 14 15 13
Salesman C 16 12 11
In which week(s), did Salesman C have a larger paycheck than both of the other salesmen? Select all that apply.
Week 3
None of the weeks.
Week 2
Week 1
Answers
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.
