Answer:
Step-by-step explanation:
If 2 men take 6 hrs to paint the fence, then
3 men would obviously take less time to paint the same fence;
2 men= 6 hrs
3 men= ?
thus, the time taken by three men to paint the same fence=2/3 ×6 hrs
= <u>4 hrs</u>

Using a system of equations, it is found that there were 4,000 children tickets sold.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given by:
- Variable x: Number of children tickets sold.
- Variable y: Number of adult tickets sold.
The attendance at the amusement park is 5,000 attendees, hence:
x + y = 5000 -> y = 5000 - x.
Considering the cost of parking and that the total money earned by the park is $100,000, we have that:
15x + 40y = 100000
Applying the multiplication of the matrices, these equations are the same that the system gives. Replacing the second equation into the first:
15x + 40(5000 - x) = 100000
25x = 100000
x = 100000/25
x = 4000.

A(a — 2)(b — 3)
a(a(b — 3) — 2b + 6)
(a — 2) ab + (6 — 3a) a
EXPLANATION
Step 1.
simplify the following:
a²b — 2ab — 3a² + 6a
Step 2.
Factor a out of a²b — 2ab — 3a² + 6a:
a(ab — 2b — 3a + 6)
Step 3.
Factor terms by grouping. ab — 2b — 3a + 6 = (ab — 2b) + (6 — 3a) = b(a — 2) — 3 (a — 2):
ab(a — 2) — 3(a — 2)
Step 4.
Factor a - 2 from b(a — 2) — 3(a — 2):
a(a — 2)(b — 3)

Yes it’s a function because it only has one output for the input
