Answer:
x = 18 , y = 15
Step-by-step explanation:
Given the 2 equations
3x - 2y = 24 → (1)
x + 2y = 48 → (2)
Adding the 2 equations term by term will eliminate the y- term
4x + 0 = 72
4x = 72 ( divide both sides by 4 )
x = 18
Substitute x = 18 into either of the 2 equations and solve for y
Substituting into (2)
18 + 2y = 48 ( subtract 18 from both sides )
2y = 30 ( divide both sides by 2 )
y = 15

Decide which of the two points lies on the graph of the line.
1. X + Y = 8
A. (2,4) B. (2,6)
2. X = 4
A.(4,2) B. (2,4)
3. Y = X - 2
A. (4,6) B. (6,4)
Answers:
B) (2,6)A) (4,2)B) (6,4)===========================================
Explanations:
For this problem, the x and y coordinates must add to 8. In choice A, we have x+y = 2+4 = 6, which doesn't work. But choice B does work since x+y = 2+6 = 8. Therefore, the point (2,6) is located on the line x+y = 8. The equation x+y = 8 is equivalent to y = -x+8.The x coordinate must be equal to 4. The y coordinate can be anything you want. The point (4,2) is on this line, while (2,4) is not. Another point on this line is (4,1). The line is completely vertical.If we plugged the x & y coordinates of choice A into the equation, we get 6 = 4-2 which then becomes 6 = 2 and that's a false statement. That rules out choice A. If we try choice B, then we get 4 = 6-2 which becomes 4 = 4. We get a true statement so choice B is the answer.pls help i’ll love u forever

if it takes 3 men 5 hours to dig 12 holes, how many hours does it take for 3 men to dig 84 holes?
Answer:
Hence it will take 35hours
Step-by-step explanation:
Let the time it took to dig hole be x
Ley the number of holes be n
Using the relationship x = kn (direct relationship)
if it takes 3 men 5 hours to dig 12 holes, hence;
when x = 5, n = 12
k = x/n
k = 5/12
To get how many hours it take for 3 men to dig 84 holes, then;
when n = 84, x = ?
x = 5/12 * 84
x = 5 * 7
x = 35hours
Hence it will take 35hours

Which of the equations matches the line shown in the diagram?
A
B)
y=-x-1
C)
D)
Answer:
The answer should be D) y = 5/3x - 1/3
Step-by-step explanation: The slope is positive ruling out the negative slope answers leaving C and D, however D is the only answer to get the y intercept correct.
Question 10
For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?
O sum = (180)(8) = 1440°
O sum = (360)(8) = 2880°
o sum = (360)(10) = 3600°
Osum = (180)(10) = 1800°
Answer:
I got sum = (180)(8) = 1440°

Give the number of terms:
cd + 3d2 – 2d
Give the number of terms
Answer:
3
Step-by-step explanation:
Given the expression
cd + 3d2 – 2d
We are to determine the number of terms
From the equation, the term so of the expression are cd, 3d^2 and -2d. From the listed functions, we can see that we only have three of them. Hence the number of terms in the expression is 3

Answer:
The fourth choice, Pink, is the correct answer.
Step-by-step explanation:
The first two options intersect, therefore the intersection is the solution. The third set of lines may seem like one line, however since we are dealing with two linear equations, it can be presumed that those are two lines on top of one another, therefore it has infinite solutions. The last option remaining is Pink, in which the lines are parallel and therefore will never intersect, making them have no solution.

Select one:
O a. 30 degrees
O b. 60 degrees
O c. 45 degrees
O d. 90 degrees
Answer:
I believe it's a because 90 + 60 would get you 150 and then you add 30 and it gives you 180/half a circle
What does slope represent
Step-by-step explanation:
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x.
Help me solve this problem please
Answer:
CD = 45
Step-by-step explanation:
CE = 180
( x + 6 ) + ( 4x - 21 ) = 180
5x - 15 = 180
5x = 195
x = 39
substitute x in CD
CD = x + 6
CD = 39 + 6
CD = 45

On her lunch break, Audrey grabs a meal with her two coworkers. If everyone paid an equal amount of $8.50, then how much was the total bill?
Answer:
$25.50
Step-by-step explanation:
3 people including Audrey went on the lunch break. If each spent $8.50, the total bill can be calculated in two ways
Method 1
$8.50 x 3 = $25.50
Method 2
$8.50 + $8.50 + $8.50 = $25.50

the function of C gives the percentage of homes using only cell phone service X years after 2004 explain the meaning of each statement.
1. C(10)=35
2. C(x) = 10
3. how is C(10) different from C(x) = 10?
Answer:
Step-by-step explanation:
1. C(10)=35 is the percentage of homes using only cell phone service 10 years after 2004, that is, after 2014.
2. C(x) = 10 is the percentage of homes using only cell phone service x years after 2004. We must find x.
3. how is C(10) different from C(x) = 10?
In C(10), 10 measures time in years and is the independent variable here; C10) is the dependent variable. See (2), above. In C(x), x is the (unknown) independent variable, whereas 10 is the output vaue, the dependent variable.

account for 7 years. Assuming the interest is
compounded monthly, what interest rate, to the nearest
tenth of a percent, would be required in order for
Alexander to end up with $3,100?
3,100= 1,900 +84x
