Subtract 7
divide by 3
you have:
3x + 7 = 13
3x = 13 - 7
3x = 4
x = 4/3
Step-by-step explanation:
2(19.2) + 4(x + 7)
= 66.4 + 4x
= 4(16.6 + x)in
Answer:
3rd option
Step-by-step explanation:
Under a rotation about the origin of 270°
a point (x, y ) → (y, - x ) , then
A (- 3, 4 ) → (4, - 3 )
B (4, - 5 ) → (- 5, - 4 )
C (1, 6 ) → (6, - 1 )
Divide the previous value by 3
Answer:
Since each Ticket cost $45 , then the number of ticket sold should be multiplied by the cost of 1 ticket , from the question, it was said that x tickets were sold, i.e the amount will be $45 multiplied by x , which is $45x. To find the profit , then we must find the cost of 18 tickets which will give us the cost price and then subtract it from the selling price ($45x).
The cost of 18 = 18 x $45 = $ 810
profit = $45x - 810
i.e y = 45x -810
clearly, comparing with the equation y = mx +c , we have a slope and y-intercept
