how do you solve 18 - (-2)=
Answer:
the answer would be 20
Step-by-step explanation:
so if 18-(-2)=?
two nwgatives make a positive. So the equation would turn into 18+2=20
Im not 100% if this is right but htis is how I was taught to do it.

Answer:
a)
28000 + 3000·x = 36000 + 2000·x --> x = 8 years
b)
28000 + 3000·8 = $52000
Answer:
a. x = 8 yearsb. 52,000Step-by-step explanation:
company A = 28,000 + 3,000 (x)
company B = 36,000 + 2,000 (x)
where x = no. of years.
company A = company B28,000 + 3,000 (x) = 36,000 + 2000 (x)
3,000 (x) - 2,000 (x) = 36,000 - 28,000
1,000 (x) = 8,000
x = 8,000
1,000
x = 8 yearsplugin value of x = 8 into company A and Bcompany A = 28,000 + 3,000 (8)
company A = 52,000company B = 36,000 + 2,000 (8)
company B = 52,000What is the y intercept of 4y+9x=18
Answer:
y = 9(2 - x)/4
Step-by-step explanation:
1.) Subtract 9x from both sides.
4y = 18 - 9x
2.) Divide both sides by 4.
y = 18 - 9x/4
3.) Factor out the common term 9.
y = 9(2 - x)/4

The y intercept of the equation of the line 4y+9x=18 is 4.5.
What is defined as the y-intercept of the line?The point at which the graph intersects this same y-axis is known as the y-intercept. Finding the intercepts of any function of the form y = f(x) is critical when graphing. A function can have one of two types of intercepts. They are recognized as the x and y intercepts. An intercept of the a function is the point at which the function's graph intersects the axis.For the given question,
The equation of the line is given as;
4y+9x=18
Write the equation in slope intercept form.
y = mx + c
Where, m is the slope and c is the y intercept.
4y = -9x + 18
y = -9x/4 + 9/4
y = -9x/4 + 4.5
Comparing with the standard form, y intercept is found as 4.5.
Thus, the y intercept of the equation of the line 4y+9x=18 is 4.5.

.Shaun estimated that the attendance at a college
volleyball game was 1,000. The actual attendance was
1,632. What is the percent error of Shaun's estimate?
Round to the nearest whole percent
Answer:
38.72%
Step-by-step explanation:
Estimated attendance = 1,000
The actual value of attendance = 1,632
We need to find the percent error of Shaun's estimate. Using the formula as follows :
[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]
Put all the values,
[tex]\%=\dfrac{1632-1000}{1632}\times 100\\\\=38.72\%[/tex]
So, the percent error of Shaun's estimate is 38.72%.

Danica is saving money to buy a used car in six months. She needs to save $1500 for a down payment in order to be able to finance the rest. She gets paid $180 per week at her part-time job. How much money will she need to save out of every weekly paycheck to reach her savings goal of $1500 in six months? Show the calculations:
Answer:
$62.5Step-by-step explanation:
Step one:
Given data
Danica's goal is to save $1500
her pay is $180 weekly.
the duration is 6months
in a month we have 4 weeks
in 6months there are 6*4= 24 weeks
Step two:
In 24 weeks Danica's earnings will be 24*180= $4320
nevertheless, she only needs $1500 for the 24 weeks to make the down payment
So per week, she will need to save 1500/24= $62.5

When Katya factored 288, she listed these factors: 1, 2, 3, 6, 8, 9, 12, 16, 18, 32, 36, 48, 72, 96, and 288. Use a factor rainbow to decide which three factors she missed.
Answer:
Please find a representation of the factor rainbow below.
The missing factors are: 4, 24, and 144
Step-by-step explanation:
The factors of a number are those numbers that can divide another number without remainder. In this case where Katya factored 288, it means she listed the numbers that can divide 288 without reminder (factors of 288). However, among the factors she listed, THREE factors are missing.
To get the missing factors, we can use a FACTOR RAINBOW, which is a display of the factors of a number in a rainbow shape. The factors are arranged from smallest to largest number in such a way that the two numbers attached to a line can be multiplied to give the original number.
From the attached factor rainbow (see attached image), it can be observed that factors: 4, 24, and 144 are missing in the list of factors Katya provided.

Lena will use 7 cups of apples to make 4 batches of applesauc. Which expression shows the number of cups of apples in each batch? Group of answer choices 4/7 3/4 1 3/4 1 1/2
Answer: 1 3/4 cups of apples in each batch
Step-by-step explanation:
STEP 1
Writing out the equation to represent if 7 cups of apples make 4 batches One batch is as a result of how many cups of apples
LET x be number of cups of apples to make each batch
7 cups of apples = 4 Batches
x cups of apples = 1 Batch
STEP 2 Solving by cross multiplication
1 batch x 7 cups of apples = 4 batches X x cups of apples
x cups of apples=1 batch x 7 cups of apples / 4batches
x = 7 / 4 = 1 3/4
number of cups of apples to make each batch= 1 3/4

Your roommate's closet is full of skeletons. There are containers full of skeletons which weigh pounds total. If there are containers, how much does each container weigh? Leave your answer in the form a^b.
Answer:
Each container weigh 10^3pounds
Step-by-step explanation:
The question lacks the necessary values. Let's restructure the question and include values.
Your roommate's closet is full of skeletons. There are containers full of skeletons which weigh 100,000 pounds total. If there are 100 containers, how much does each container weigh? Leave your answer in the form a^b.
From the question, we are given the following;
Weight of containers full of skeleton = 100000 pounds
Number of containers = 100
Required
Weight of each container
Let's say:
100containers = 100000pounds
1 container = xpound
Cross multiply
100×x = 100,000
Divide both sides by 100
100x/100 = 100,000/100
x = 10,000/100
x = 10^5/10^2
Using the law of indices
x = 10^{5-2}
x = 10^3
Hence the answer in form of a^b is 10^3 pounds.
