Answer:
Let the no. Of cheese pizzas be x
Let the no. Of pepperoni pizzas be y
x + y = 45 (No. Of pizzas)
x = 45 - y
6x + 8.5y = 365 (cost of pizzas)
6(45-y) + 8.5y = 365
270 - 6y + 8.5y = 365
2.5y = 365 - 270
2.5y = 95
y = 95/2.5
y = 38
x = 7
Therefore 7 cheese pizzas were sold and 38 pepperoni pizzas were sold
Hope this helps!
Answer:
The x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).
Join those two points with a straight line and get the graph.
Step-by-step explanation:
The intercept form of a straight line equation is , where the x-intercept of the line is at (a,0) and the y-intercept will be at (0,b).
So, we have to arrange the equation of a straight line in the intercept form and then we can easily find the x-intercept and y-intercept of the line.
Given equation is x + y = 2
⇒
Therefore, the x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).
Now, locate the two points as obtained on the graph and join them with a straight line and you will get the graph of the line. (Answer)
Answer: the answer is 7
Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40
7(7)=49 next 49-9= 40
it checks out, so x= 7

Answer:
mean = sum of the terms/total no. of terms
mean = (16+12+13+22)/4
mean = 63/4 or 15.75
