Answer: h<250. B is the answer.
Explanation:
5 x 50 = 250
She has 250 possible heights (in feet).
To only make 1/3 of the recipe you would divide all ingredients by 3 or multiply by 1/3, same thing.
Convert 2 1/4 to single fraction first
9/4 * 1/3 = 9/12 = 3/4 cup sugar
4(-6x – 3) + 24x = -72x + 132
Step 1 -24x – 12 + 24x = -72x + 132 Distribute Property of Equality
Step 2: –12 = -72x + 132 equivalent
Step 3: -144 = -72x Subtraction Property of equality
Step 4: 2 = x Equivalent / Division property of equality
Answer:
6. The set of non-positive integers includes 0 while the negative integers do not.
7. 3 x π does not give a rational number, but another irrational which is 3π.
8. Addition and Multiplication
9. 9-(8-7) which is 8 is not equal to (9-8)-7 which is -6.
10. Zero. Any number added to zero is equal to the number itself.
11. 1/x.
Answer: 6 people ordered for the lobster dinner.
2 people ordered for the steak dinner.
Step-by-step explanation:
Let x represent the number of people that ordered the lobster dinner.
Let y represent the number of people that ordered the steak dinner.
A family of 8 went out to dinner. This means that
x + y = 8
Each person either ordered the lobster dinner, which costs $25, or the steak dinner which cost $20. The total cost of all the meals is $190. This means that
25x + 20y = 190 - - - - - - - - - -- -1
Substituting x = 8 - y into equation 1, it becomes
25(8 - y) + 20y = 190
200 - 25y + 20y = 190
- 25y + 20y = 190 - 200
- 5y = - 10
y = - 10/ - 5
y = 2
x = 8 - y = 8 - 2
x = 6
