Answer:
There are total 55 counters out of which 11 are green and 44 are other color.
Step-by-step explanation:
This is a ratio and proportion question. There are c amount of counters in the box .
The chosen have the same ratio as in the box
Green : total
4: 20
11: x
Using cross product rule
x * 4= 20 *11
x= 20*11/4
x= 55
So there are total 55 counters out of which 11 are green and 44 are other color.
Benedict take 20 counters out of which 4 are green.
True. Using the equation y2-y1 / x2-x1
The new equation should look like this 5/1-3/1 and the equals to = 4/2 and that simplify is 2. So the answer 2 we just got is the slope. So we just add the letter x since that represents slope. Making the equation y=2x+1 true.
6/15 in simplest form is 2/5.
Divide the numerator and denominator by 3. :)

Answer:
Front section tickets: $40
Back section tickets: $25
Step-by-step explanation:
If x is the price of back section tickets, and x + 15 is the price of front section tickets, then:
275 (x + 15) + 325 x = 19125
275 x + 4125 + 325 x = 19125
600 x = 15000
x = 25
So back section tickets are $25, meaning front section tickets are $40.
