Answer:
14 boys
Step-by-step explanation:
4/4-3/4=1/4 which is the fraction of boys then do 1/4x56=14 which gives you the actual number of boys going.
Answer:
Less than.
Step-by-step explanation:
I have included the explanation in bullet points so it is easier to understand.
We don't even need to solve the problem in order to find out.
- We know that any number times one is itself
- We know that any number times less than one would be less than itself.
- In order to get a product more than 6/10 we would need to multiply it by something more than 1.
- 2/3 is not more than one, which means the product would be less than 6/10
Hope this helps!

Answer:
The answer to your question is l = 12 and w = 7/2 or 3.5
Step-by-step explanation:
Data
length = l
width = w
Area = 42 yd²
Process
1) Write equations that help to solve this problem
Area = length x width = l x w
Length = 2width + 5 or l = 2w + 5
2) Substitution
42 = lw Equation l
l = 2w + 5 Equation ll
42 = (2w + 5)w Substitute equation ll in l
3.- Expand
42 = 2w² + 5w
2w² + 5w - 42 = 0
Solve the equation by factoring
-Multiply 2 by 42
2 x 42 = 84
-Find the prime factors of 84
84 = 2² 3 7
-Find two numbers that added gives +5 using the prime factors
These numbers are +12 and -7
-Substitute the values in the equation
2w² -7w + 12w - 42
-Factor by grouping
w(2w - 7) + 6(2w - 7)
(2w - 7)(w + 6)
-Find w
2w₁ - 7 = 0 w₂ + 6 = 0
w₁ = 7/2 w₂ = -6 This value is discarted because
there are no negative values
-Find l
l = 2(7/2) + 5
l = 7 + 5
l = 12
