You can subtract a negative number from a positive number or add a positive number to a negative number
Example:
4 - (7) = -3
Or
-8 + 9 = 1
Whatever you are adding has to be greater than the number you are adding on too
Example:
-3 + 5 = 2
Notice how the five is greater than 3
Whatever you are subtracting has to be Greater than the number you are subtracting from.
Example:
5 - 8 = -3
Notice how the eight is greater than five.
The situation changed when adding or subtracting with negative numbers. Every situation is different.
Hope this helps!
If you take a certain number and write a 9 to the right of it and add the doubled certain number to the result, the sum will be equal to 633. Find the certain number.
Hello,
let's say x is a certain number
10*x+9+2x=633
12x=624
x=52
Proof:
529+104=633
When you add 6 to the product of a number and 10, the result is 36. What is the number?
A) 3
B) 6
C) 2
D) 4
Answer: the number is 3.
Step-by-step explanation:
(x × 10) + 6 = 36
[(3) × 10] + 6 = 36
Answer:
3
Step-by-step explanation
First let's create an equation
Let x = number
Product is outcome of multiplication
The product of 10 and a number can be written as 10x
Were supposed to add 6 to the product and that should equal 36
So the equation is 10x + 6 = 36
We now solve for x using basic algebra
10x + 6 = 36
Subtract 6 from both sides
10x = 30
Divide both sides by 10
X = 3

Answer:
17/24
Step-by-step explanation
Answer:
17/24
Step-by-step explanation:
First, find the common denominator.
Common denominator = 24
1/12 * 2 = 2/24
5/8 * 3 = 15/24
Add.
2/24 + 15/24 = 17/24
Can 17/24 be simplified?
17/24 can not be simplified, because 17 is a prime number and 24 is not divisible by 17 without getting a decimal.
9(5x + 1) ÷ 3y From the expression above, provide an example of each of the following: sum, term, product, factor, quotient, and coefficient. If any are not present, write "not present." i need in 1 hour
Answer:
3 ( 5x + 1) / y
Answer.
Sum = 5x + 1
Term = 9 (5x + 1) ÷ 3y
Product = 9 (5x + 1)
Factor = (x - 1)
Quotient = [tex]\frac{15x + 3}{y}[/tex]
Coefficient = 15
Louise owns a hot dog stand. The amount of money she collects from selling hot dogs each day can be found by using the equation y=3.5x What does 3.5 from the equation represent in the situation?
Answer:
3.5 represents the cost of each hotdog ($3.50).
Step-by-step explanation:
In y = 3.5x, the x represents the number of hotdogs and the y represents the total amount you have to pay for those hotdogs. The 3.5 represents the cost of each hotdog.

State if is they are functions or not by filling in the blanks yes or no.
For a function, each x term must correspond to exactly one y term. We can use the vertical line test to determine whether or not that holds true for the following 6 graphs. If each x term corresponds to exactly one y term, then any vertical line that we draw on the graph should hit the graph at only one point.
1. We can't draw a vertical line that hits the graph at more than one
point so this relation must be a function.
2. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.
3. We can't draw a vertical line that hits the graph at more than one
point so this relation must be a function.
4. We can't draw a vertical line that hits the graph at more than one
point so this relation must be a function.
5. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.
6. We can draw many vertical lines that will hit the graph at more than one point. Thus, we can conclude the graph shown here is not a function.

The graph of a function is shown:
A coordinate grid is shown from negative 5 to 5 on both axes at increments of 1. A graph shows three straight lines. The first straight line joins ordered pair negative 3, negative 2 with negative 2, 2. The second straight line joins ordered pair negative 2, 2 with 2, 2. The third straight line joins ordered pair 2, 2 with 4, 0. The ordered pair negative 3, negative 2 is labeled as A, the ordered pair negative 2, 2 is labeled as B, the ordered pair 0, 2 is labeled as C, the ordered pair 2, 2 is labeled as D, and the ordered pair 4, 0 is labeled as E.

Shawn purchased $87.06 worth of merchandise at a department store. He gave the clerk $100.
Round to the nearest whole dollar to estimate how much change Shawn will receive.
What is the actual amount of change Shawn will receive?
100-87.06=12.94
$13(nearest dollar)
$12.94(actual)
Answer:
10
Step-by-step explanation:
because rounding 87 its 90, so 100-10=90.

Aight let's answer this step by step
What you need to know is if two values are equal either one will be similar to the other it's only the format that's different if you calculate each of the fractions you'll see each pair is equal except for the last option
Where if calculated
8/3=2.67 but
5/4.8=1.04
Therefore values aren't equal to each other

Leon used the number line below to show -5 + 4. explain what is wrong with his model.
can anyone help me I'm confused?
Answer: 10 inches
Step-by-step explanation:
If the two triangles are similar, that means their sides are proportional to each other.
JK = 15JL = 15 + 6 = 21JM = 14The proportion would look like this:
[tex]\frac{JK}{JL} =\frac{JN}{JM}\\[/tex]
Substitute in the values:
[tex]\frac{15}{21} =\frac{JN}{14}[/tex]
Cross-multiply and solve for JN:
[tex]21*JN=15*14\\JN=\frac{15*14}{21} =\frac{210}{21} =10[/tex]
Answer:
10 inches
Step-by-step explanation:
JM=14<JL=21
And you know that JN=X<JK=15
You also know that JM=14>JN=x
KL=6 so NM=4
JM= (14) - NM (4)= 10
Hope this makes sense, and can help!

Eight hundred tickets are sold for a play. Thirty-five percent of those tickets were sold in advance. Which equation can be used to find the number of tickets sold in advance? StartFraction 800 divided by 8 Over 35 divided by 8 EndFraction = StartFraction 100 Over 4.375 EndFraction StartFraction 100 divided by 8 Over 800 divided by 8 EndFraction = StartFraction 12.5 Over 100 EndFraction StartFraction 35 times 8 Over 800 times 8 EndFraction = StartFraction 280 Over 6400 EndFraction StartFraction 35 times 8 Over 100 times 8 EndFraction = StartFraction 280 Over 800 EndFraction
Answer:
0.35(800)=x
x=number of tickets sold in advance
Step-by-step explanation:
Answer:
Divide 35÷100 which equals 0.35 then multiply 0.35×800 which equals 280 so the answer is 280 so the equation is 0.35×800=280.
