Answer: 4 questions
Step-by-step explanation:
16h=10 min
2/3=40 min
Use equation:
1:10=x:40
40=10x
x=40/10
x=4
Answer:
28 books
Step-by-step explanation:
Let x represent the number of books .William owned before anything happens
x/2 + 10 = 24
2(x/2 + 10) = 2(24)
x + 20 = 48
x = 48 - 20
x = 28
The required equation is:

Step-by-step explanation:
Given
Let a be Anne's Age
and
b be Betty's age
Now we will onvert the given word problem in the form of equation step by step
"twice Betty's age." will be represented by 
Then
"3 years younger than twice Betty's age." will be represented as: 
Now
"Betty's sister, Anne, is 3 years younger than twice Betty's age."

Hence,
The required equation is:

Answer: OPTION A.
Step-by-step explanation:
By definintion, a function intersects the x-axis when the value of "y" is zero (
).
Then, knowing this, you need to observe the table provided in the exercise and look for the value of
when
.
So, you can notice that when
, the value of "x" is:

Therefore, this means that the function shown in the table intersects the x-axis at the following point:

Answer:
2x < 5
2x/2 < 5/2
x < 5/2
x ∈ ( -∞, 5/2 )
