Answer: B. 5 carpenters and 4 masons. Is $2,150
Step-by-step explanation:
250 • 5 = 1,250
225 • 4 = 900
1,250 + 900 = 2,150
$2,150
The answer is 30. 2x6 is 12 so you would do 5x6 which is 30
Answer:
80
Step-by-step explanation:
Let the number of adults be x
Let the number of children be y
This means that the money paid by adults and kids is $5 multiplied by x (5x) and $2.50 multiplied by y (2.5y)
This will give two equations as shown below
x + y = 240 <em>total admissions......................... equation 1</em>
5x + 2.5y = 800 <em>total money paid..................equation 2</em>
<em />
<em>Making x the subject of formula in equation 1</em>
x=240-y<em>......................................................equation 3</em>
Substituting equation 3 into equation 2
5(240-y) + 2.5y = 800 <em>removing the brackets</em>
1200 - 5y + 2.5y = 800 <em>grouping like terms</em>
-5y + 2.5y = 800-1200 <em>simplifying </em>
-2.5y = -400 therefore
-2.5y/-2.5 = -400/-2.5
y = 160
<em>Substituting y into equation 3</em>
x = 240 - y
x = 240 - 160
x = 80
Hence number of adults who attended = 80

Answer:
x-intercept is 24 , y-intercept is -16
Step-by-step explanation:
* Lets explain how to solve the problem
- The x-intercept is the x-coordinate of the point of intersection
between the graph of the equation and the x-axis ⇒ (x , 0)
- To find the x-intercept substitute the value of y in the equation by 0
- The y-intercept is the y-coordinate of the point of intersection
between the graph of the equation and the y-axis ⇒ (0 , y)
- To find the y-intercept substitute the value of x in the equation by 0
* Lets solve the problem
∵ 2x - 3y = 48
- To find the x-intercept substitute y by 0
∴ 2x - 3(0) = 48
∴ 2x = 48
- Divide both sides by 2
∴ x = 24
∴ The graph intersects the x-axis at point (24 , 0)
* The x-intercept is 24
∵ 2x - 3y = 48
- To find the y-intercept substitute x by 0
∴ 2(0) - 3y = 48
∴ -3y = 48
- Divide both sides by -3
∴ y = -16
∴ The graph intersects the y-axis at point (0 , -16)
* The y-intercept is -16
