Step-by-step explanation:
It will take 5 years because when you add 5 to Stephanie's age = 18 + 5 = 23
And Ashley age = 64 + 5 = 69

This means after 5 years Ashley will be 3 times as old as Stephanie
Answer:
<h3>1404</h3>
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right. Please Excuse My Dear Aunt Sally!
BOMDAS stands for (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
52*(4+23)
4+23=27
52*27
Then, multiply.
52*27=1404
1404
The correct answer is 1404.
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
