The unknown number would be 16.
8 times 2 is 16
Y=-3x+5 because the line crosses the y-axis at (0,5) and the slope is -3 because the rise/run saying it goes down 3 and over 1 which can be simplified to -3.
Substitute value of y from equation (1) in equation (2),
5x-4(5-3x) = -3
5x-20+12x = -3
17x=17
x = 1
Substitute it in equation (1),
y = 5-3(1)
y = 5-3 = 2
So, the values (x,y) = (1,2)
Answer:
23/50
Step-by-step explanation:
27 + 23 = 50 (Implying that 50 is the total amount of tickets).
23 of them were sold to adults, so basically 23/50.
Remember a ratio can be written in 3 forms, so it can be either of these:
23:50
23/50
23 to 50
You turn the decimal into a percent
