If (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
The answer would be Find 40% of 20 because you would round 43% down and 18 up. Hope this helps :)
Answer:
Combine Like terms and do the Equation normally
Step-by-step explanation:
An equation that models the proportional relationship between t and s.
t = 12.5s
<h3>What is proportional relationship?</h3>
Relationships between two variables where their ratios are equal are known as proportional relationships. The fact that one variable is always a constant value multiplied by the other in a proportionate connection is another way to conceive of them. This parameter is referred to as the "constant of proportionality."
<h3>According to the given information :</h3>
1) Ticket for an art museum costs $12.50
2) In other words, the price will increase by $12.50 for each ticket purchased (or tickets).
In other words, the total expense is always 12.5 times the quantity of tickets sold.
3) This indicates that we can create this ---> t = 12.5s.
An equation that models the proportional relationship between t and s.
t = 12.5s

Answer:
x = 7 and 15
Step-by-step explanation:
Divide both sides by -4...
| x - 11 | = 4
because
| -4 | = 4 and
| 4 | = 4
x - 11 = -4 and x - 11 = 4
solve for x in both equations.
x = 7 and x = 15
