Example:
A truck can tow at most 12,000 lbs.
Let t represent the amount that the truck can tow.
t ≤ 12,000
8. The restaurant can seat at most 172 people.
9. A person must be at least 35 years old to be elected president.
10. A law clerk earned more than $20,000 since being hired.
11. A local pizzeria offered a special. Two pizzas cost $14.99. A group of students spent less than $75. They purchased three pitchers of soda for $12.99. How many pizzas could the group purchase? (1 point for writing an inequality to represent this situation, 1 point for determining how many pizzas could be purchased)
8/13 and 7/10.
z = 4
z = -28
z = -112
z = 784
The solution of expression is,
⇒ z = 4
We have to give that,
An expression to solve is,
⇒ 70 = - 7 (- 2 - 2z)
Now, Simplify the expression as,
⇒ 70 = - 7 (- 2 - 2z)
Divide both sides by 7,
⇒ 70/ 7 = - 7 (- 2 - 2z)/7
⇒ 10 = - 1 (- 2 - 2z)
Apply distributive property,
⇒ 10 = 2 + 2z
Subtract 2 on both sides,
⇒ 10 - 2 = 2z
⇒ 2z = 8
Divide on both sides by 2,
⇒ z = 8/2
⇒ z = 4
Therefore, The solution is,
⇒ z = 4
