Answer:
Part A)
Part B)
Part C) The graph in the attached figure
Step-by-step explanation:
Part A) Model with an inequality.
Let
w -----> the limit of weight in an elevator
we know that
The inequality that represent this situation is
Part B)
Solve the inequality
solve for w
Subtract 35 sides
All real numbers greater than 1,015 pounds
Part C) Where would the solution for the inequality be graphed on the number line?
The solution is the interval -------> (1,015,∞)
In a number line is the shaded area at right of the number x=1.015 (open circle)
see the attached figure
There are 15 mini hotdogs and 5 mini pizza rolls in the combination meal.
Step-by-step explanation:
Given,
Calories in each hotdog = 80 calories
Calories in each mini pizza = 50 calories
Combined meal = 20
Combined calories = 1450 calories
Let,
x represent the number of hot dogs.
y represent the number of mini pizzas.
According to given statement;
x+y=20 Eqn 1
80x+50y=1450 Eqn 2
Multiplying Eqn 1 by 80
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 30
Putting y=5 in Eqn 1
There are 15 mini hotdogs and 5 mini pizza rolls in the combination meal.

9* x/6=9/(x/6), what is x
Divide both sides by 9
x/6=1/(x/6)
Simplify
x/6=6/x
Cross multiply
36 =x^2
x=+-6
I hope this helps you
-9= -4x/5 -2
-7= -4x/5
-35= -4x
x= 35/4
The gcf would be 12 because both 12 and 36 can be divided by 12 and it is the highest number
