Find value of X please
Answer:
x=7
Step-by-step explanation:
Step #1- Set the two lines equal to each other
10+12=x+15
Step #2- Solve for the line you have all values for
10+12=22
Step#3- Plug 22 back into the equation where the two lines are set equal to each other
22=x+15
Step #4- Solve for X algebraically
22=x+15
22-15=x
7=x
Rob bought a hat and 3 shirts for $35 . Dan bought 2 hats and a shirt for $20 Which system of equations can be used to find s , the cost of one shirt, and h, the cost of one hat?
Answer:
1x+3y=35, 2x+y=20
x=5, y=10
Step-by-step explanation:
Let x equal the number of hats and y equal number of shirts.
Solve by substitution, elimination, or graphing.
Personally, I just solved by substitution.
Solve for x (or y) in the first equation. Let's do x.
1x+3y=35 goes to 1x=35-3y or just x=35-3y.
Since we have x, plug it in the other equation. 2(35-3y)+y=20. This equals out to y=10, i assume you understand the algebra.
Plug 10 into either equation for y.
1x+3(10)=35 or x+30=35. subtract 30 on each side. X=5.

Draw the graph of y = 3 - 1/2x
Answer:
Answer attached
Step-by-step explanation:
The graph for the line is attached below.
What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
y = 3 - 1/2x
Now, let us find the point to plot on the graph.
So, take x= 0
y= 3
and, take x= 2
y= 3- 1
y= 2
and, take x = 6
y = 3 - 3
y= 0
Thus, the points are (0, 3), (2 , 2) and (6,0).

Mrs. Anderson's car can go 464 miles on 16 gallons of gasoline. How many miles
can the car travel on 22 gallons of gasoline?
Answer:
638 miles
Step-by-step explanation:
Key skills needed: Proportions, Unit Rates
1) The car can go 464 miles with 16 gallons of gasoline. We need to find how many miles each gallon gasoline results in.
To find the miles per gallon, we would do 464 miles/16 gallons --> 29 mpg
This means each gallon lets the car run 29 miles.
2) To find out how many miles 22 gallons is, we then do 29 x 22, which is 638 miles.
Therefore, your answer is 638.

California, the most populous state, has approximately 40,000,000 people living in it. The population of the entire United States is about 3E8 people. About how many times greater is the population of the United States than the population of California?
State operation used and write answer in proper scientific notation (can use e)
Answer: 7.5 E 0
This is the same as saying 7.5 * 10^0
Both of these values convert to the number 7.5; meaning that the population of the US is about 7.5 times greater than the population of CA.
==========================================================
Work Shown:
40,000,000 = 40 million
40,000,000 = 4.0 * 10^7
Note how we move the decimal 7 spots to the right to go from 4.0 to 40,000,000
so the 7 in 10^7 tells us how many spots to move the decimal point in the base number 4.0
The number 4.0*10^7 can be condensed to 4E7. The "E" represents "times 10 to the"
As another example, "3E8" means "3 times 10 to the 8th power" which becomes 3.0*10^8 = 300,000,000 = 300 million
--------------------------
We have these two facts
x = Population of CA = 4 E 7 = 4*10^7y = Population of US = 3 E 8 = 3*10^8We'll divide the two populations to get
y/x = (3E8)/(4E7)
y/x = (3*10^8)/(4*10^7)
y/x = (3/4)*10^(8-7)
y/x = 0.75*10^1
y/x = 7.5
We can see that the population of the US is roughly 7.5 times greater compared to the population of CA.
Convert 7.5 to scientific notation, and we get
7.5 = 7.5*1 = 7.5 * 10^0 = 7.5 E 0
Keep in mind that these are population estimates, and populations change over time.

Answer:
1: x = 47, y = 902: x = 92, y = 88, z = 923: 284: x = 90, y = 855: 133Explanation:
[1] - Ay = 90 (90 degree angle)
90 - 43 = 47, so x = 47
[2] - Cx = 92 because 180 - 88 = 92
x = 92 and y = 88 because 92 + 88 = 180
[3] - Cx = 28 because 90 - 62 = 28
[4] - Dx = 90 because 180 - 90 = 90
y = 85 because 42 + 53 = 95, 180 - 95 = 85
[5] - Ax = 133 because 180 - 47 = 133

The required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.
What is average?The average of the values is the ratio of the total sum of values to the number of values.
Here,
The required average of three test scores,
= sum of the scores/number of scores
= x + y + z / n(x, y, z)
= x + y + z / 3
Thus, the required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

Stacy spins the pointer 120 times and records it. The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6. A winning spin is a 2. FIND THE EXPERIMENTAL PROBABILITY OF LANDING ON 2
Answer:
1 / 4
Step-by-step explanation:
Number of trials = 120
Landing on 2 = 30
Landing on 3 = 19
Landing on 4 = 25
Landing on 5 = 29
Landing on 6 = 17
The experimental probability of landing in a two:
Experimental probability :
Number of times event occurs / Number of trials
Number of 2 landings = 30
Experimental probability of landing in a 2 ;
30 / 120 = 1/4
