Answer:
20 people
Step-by-step explanation:
Let x be the number of people initially. We can find the amount each of them has to pay at first
2 / x
But when 10 people walk away, the remaining (x - 10) has to pay 10 cents more to get the same total of $2. This would means
From here we can perform cross multiplication
Multiply both sides by 10x:
x = 20 or x = -10
Since x can only be positive we will pick x = 20
Answer:
x=40
Step-by-step explanation:
In the picture, it seems that angles BHC, CHD, and DHE form a line, 180 degrees. So to solve, set up an equation:
Take off the parentheses and solve.
Subtract 5, 55 and 40 from both sides, or add them together, then subtract.
5+55+40=100
You get:
Divide both sides by 2
You get:
