How can you use addition rules to solve subtraction problems with integers?
Answer:
Not entirely sure about what the question is asking, but explanation of what I think it is asking.
Step-by-step explanation:
There are three basic rules of addition.
Positive + Positive = Positive Ex: 1+1=2
Negative + Negative = Negative Ex: -2+-2=-4
Negative + Positive = Positive or Negative depending on the value.
Ex= 1+(-2)=(-1)
Ex=2+(-1)=1
So subtraction problems can be turned into addition problems.
For example:
4-2 is the same as 4+(-2).
Or -5-7 is the same as -5+(-7).
Hope this makes sense.
Find the length of BC.
Answer:
BC = 8
Step-by-step explanation:
AB + BC = AC
4x + 8 + 3x - 4 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
x = 28/7
x = 4
BC = 3x - 4 = 3*4 - 4 = 12 - 4 = 8
Answer:
B) 8
Step-by-step explanation:
The Segment Addition Postulate basically states that the sum of the segments of a line will equal the length of the entire line.
Thus, AB+BC=AC, and we can substitute:
AB+BC=AC
(4x+8)+(3x-4)=32
4x+8+3x-4=32
7x+4=32
7x=28
x=4
Now that we have x, we can plug it in for segment BC:
BC=3x-4
3(4)-4
12-4
8
Therefore, choice B is correct

1. The price of the video game was $60.00. Thelprice was reduced by 25%. What was the sale price of the video game? A $15.00 B. $25.00 C. $45.00 D. $75.00
Answer:
The answer is A. $15.00
Step-by-step explanation:
Take 25% of 60 and that is 15. Please give me brainliest
Answer:
$45.00
Step-by-step explanation:
To find percentage, most start out by dividing the percent by 100:
25 ÷ 100 = 0.25
Then, to find the percentage of 60, we multiply them.
$60 x 0.25 = $15
15 is 25% of 60. However, we're asking the sale price of the video game, not the amount it was reduced. To find this out we subtract the reduced amount from the original number:
$60 - $15 = $45

George is buying gifts for his three sisters. He has $45 to spend and has a coupon for $12 off. Write an inequality to represent the amount he can spend.
Answer:
The inequality that represents how much George can spend is y ≤ $45 + $12, which gives y ≤ $57
Step-by-step explanation:
The given parameters are;
The amount George has to spend for his sisters = $45
The amount of coupon George has = $12
The inequality that represents how much George can spend, y, is given as follows
y ≤ $45 + $12.

Which graph represents the inequality?
y>- 1/2
OA
OB
OC
OD
Answer:
A
Step-by-step explanation:
Given the inequality, y > -½, the graph that represents this would have a directed line starting from -½ and pointing to your right. It would also have an unshaded circle, or empty circle, signifying that -½ is not included among the set of possible values of y.
Thus, the right graph would be graph A.

Write the following ratio in simplest form: 2 to 4
Answer:it would be 1:2
Answer:
1 : 2
Step-by-step explanation:
2 : 4
A ratio is another way of expressing a fraction. Hence, if one divides both sides by the same number, it will be the equivalent of one reducing a fraction, and it will still be equivalent to the original value. Hence, to reduce this ratio; divide both sides by 2
1 : 2

Is 3xy + 8 = 4y a linear equation ?
Answer:
No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given
The answer is 3xy + 8 = 4y is not a linear equation.
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here: 3xy + 8 = 4y
The degree of this equation is 2 and thus the graph of this equation is not linear.
Hence, 3xy + 8 = 4y is not a linear equation

Here is a riddle: “I am thinking of two numbers that add up to 5.678. The difference between them is 9.876. What are the two numbers?”
The riddle can be represented with two equations. Write the equations
Answer:
X + Y = 5.678
X - Y = 9.876
The two numbers: X = 7.777 Y = -2.099
Step-by-step explanation: solve by elimination
X + Y = 5.678
X - Y = 9.876 . Add the two equations so the y cancels. Solve for x
2x = 15.554 . Divide both sides by 2
X = 7.777 Substitute in the original equations to find Y
7.777 + y = 5.678 . Subtract 7.777 from both sides
Y = - 2.099
check in the second equation:
7.777 -(-2.099) = 9.876
7.777 + 2.099 = 9.876 True
The two numbers is X = 7.777 and Y = -2.099.
And, the two equation is X + Y = 5.678 and X - Y = 9.876.
Given that,
I am thinking of two numbers that add up to 5.678. The difference between them is 9.876.Here we assume the one number be X and the other number be Y.
Based on the above information, the calculation is as follows:
X + Y = 5.678
X - Y = 9.876
2x = 15.554
X = 7.777
Now
7.777 + Y = 5.678
Y = - 2.099
Therefore, the above should be the answers.
