Solve the system of equations using subsititution.
y = 2x - 3
y + 5 = 3x
Answer:
(2,1)
x = 2
y = 1
Explanation:
Check the image
Answer:
(2,1)
Step-by-step explanation:
Since we already have an equation for y, all we need to do is plug that into y in the other equation.
y + 5 = 3x
(2x - 3) + 5 = 3x
2x - 3 + 5 = 3x
2x + 2 = 3x
2 = x
Now that we know y, we just need to plug the value of x into the equation.
y = 2(2) - 3
= 4 - 3
= 1
Find the percent change from the first value to the second 50;31
Answer:
-0.38%
Step-by-step explanation:
Divide 31 by 50. 31 / 50 = 0.62.
1 - 0.62 = 0.38
Since it is a decrease in change the percent change is negative.
-0.38%

When have you felt scared of someone you didn’t know? How did you overcome this
fear?
give me a fake story.
Answer:
the most I have ever felt fear of someone was ar a local gas station or my job lol but basically I was working behind the register and this couple comes in and looks pretty sus but I don't think much of it so I greet them and scan all their items and right as I bag their stuff, the wife literally takes the bag, swings it around, and knocks me out and then they run off with their stuff. So I was left there unconscious for about a hour before the next customer came and called the police. I haven't nessecarily gotten over that fear yet but I do have a glock now.

You spin the spinner shown. The spinner lands on blue or green.
Answer:
[tex]$\frac{1}{3}$[/tex] , 0.33 , 33%
Step-by-step explanation:
The spinner has 4 green, 4 blue and 4 yellow.
So total = 12
Therefore, the probability of the spinner landing on blue or green as a fraction is = [tex]$\frac{4}{12}$[/tex]
[tex]$=\frac{1}{3}$[/tex]
The probability of the spinner landing on blue or green as a decimal is = 0.33
The probability of the spinner landing on blue or green as a percent is
= 0.33 x 100
= 33 %

the area is 24cm squared
Step-by-step explanation:
Average attendance at a school’s basketball games increased from 1,000 to 1,500 last year. One student said that represented a 150% increase. Explain the student’s mistake. What is the actual percent increase?
Answer:
50%
Step-by-step explanation:
Since 1,000 is 100% of the attendance, 500 is half of 1,000 meaning it's 50%.
I think the student added 50% and 100%, they could have also divided 1,500 by 10.
The actual percent increase would be equal to 50 percent.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means). Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]
We have been given that the Average attendance at a school’s basketball games increased from 1,000 to 1,500 last year. a student said that represented a 150% increase.
Since 1,000 is 100% of the attendance, 500 is half of 1,000 which means that it's 50%.
The student added 50% and 100%, they could have also divided;
1,500 by 10
Therefore, the actual percent increase would be equal to 50 percent.

The line plot below shows the lengths of bolts Mr. Slivka found in his drawer.
He needs 16 bolts that are longer than 1 inch for a project he is working on.
Does he have enough bolts for his project?
A line plot named
A.
Yes. There are 16 bolts that have lengths greater than 1 inch, which is just enough.
B.
Yes. There are 18 bolts that have lengths greater than 1 inch, which is more than enough.
C.
No. There are only 3 bolts with lengths greater than 1 inch, which is not enough.
D.
No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.
Answer:
D.)
No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.
Step-by-step explanation:
Based on information provided by the dot plot above, we can deduce that the number of bta longer Than 1 inch are those with length ; 1 1/8, 1 3/8, 1 4/8
Counting the number of these bolts :
1 1/8 = 5 bolts
1 3/8 = 3 bolts
1 4/8 = 4 bolts
Hence, total number of bolts longer Than 1 inch :
(5 + 3 + 4). = 12 bolts
The number of bolts longer than 1 inch is 16. Therefore, he does not have enough bolt for the project.

Steve will roll a number cube, numbered 1-6, twice. What is the probability of rolling a number greater than 4, then
rolling an odd number?
Answer:
6/36 or 1/6
Step-by-step explanation:
To find the probability of rolling a number greater than 4, then rolling an odd number, you must multiply the probability of rolling numbers greater than 4 by the probability of rolling an odd number. In numbers 1-6, there are two number greater than 4: 5 and 6. The probability of an event is the specific factor over the total amount of results or objects. The probability of rolling a number higher than 4 is 2/6, or 1/3. In numbers 1-6, there are 3 odd numbers: 1, 3, and 5. The probability of rolling an odd number is 3/6, or 1/2. 3/6 times 2/6 is 6/36, and when simplified, it becomes 1/6.

PLZZZZZ HELPPPP!!!! i'm very confused on what to do !!!! what is the length of the apothem of a regular hexagon with 16cm side lengths round to the nearest tenth
Answer:
A = 4.6 cm
Step-by-step explanation:
Here, we want to find the length of the apothem, given the side lengths
Mathematically, we have this as;
A = s/2 tan (180/n)
where in this case;
s is the length of the sides which is 16 cm
n is the number of sides (since it is hexagon, we have this as 6)
Substituting these values;
A = 16/2 * tan (180/6)
A = 8 * tan 30
A = 4.62
To the nearest tenth, A is 4.6 cm

find the value of x
−8(x−6)=32
Answer:
x = 2
Step-by-step explanation:
-8(x-6) = 32 (distribute)
-8x+48 = 32 (subtract 48 from both sides)
-8x = -16 (divide)
x = 2
Answer:
x = 2
Step-by-step explanation:
Divide both sides :
−8(x−6)=32
Divide both sides of the eqaution by -8 :
x - 6 = -4
Move the constant to the right :
x - 6 = -4
Move the constant to the right - hand side and change its sign :
x = -4 + 6
Calculate :
x = -4 + 6
Calculate the sum :
x = 2
Therefore, the answer is x = 2

Answer:
38.1 cm²
Step-by-step explanation:
area of full circle = π6² = 113.04 cm²
area of 150° segment = (150/360)(113.04) = 47.1 cm²
triangle base = sin 75° x 6 x 2 = 11.59
triangle height = cos 75° x 6 = 1.553
area of triangle = 1/2(11.59)(1.553) = 9 cm²
150° segment - triangle = 47.1 - 9 = 38.1 cm²

A company used 7.4 x 105 sheets of paper a month, the accounting department used 8.9 x 103 sheets. How many were used by other departments during the month
Answer:
731,100
7.311 × 10^5
Step-by-step explanation:
The computation of the number of sheet used by other department is given below:
Given that
The company used 7.4 × 10^5 sheets of paper So it would be 740,000
And, The accounting department used 8.9 × 10^3 sheets so it would be 8,900
Now the number of sheet used by other department is
= 740,000 - 8,900
= 731,100
= 7.311 × 10^5
