Constraints are simply the subjects of an objective function.
The inequality that represents the constraint is: 
Represent the number of hats with x, and the number of scarves with y.
From the question, we have:
- He spends 12 hours to knit a hat
- He spends 6 hours to knit a scarf
So, the equation of the total time spent is:

This time spent is not more than 20 hours.
So, the inequality is

Hence, the inequality that represents the constraint is:

Answer:
x = 2
Step-by-step explanation:
Step 1: Convert to math
5x + 1 = 3x + 5
Step 2: Solve for <em>x</em>
- Subtract 4x on both sides: 2x + 1 = 5
- Subtract 1 on both sides: 2x = 4
- Divide both sides by 2: x = 2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(2) + 1 = 3(2) + 5
10 + 1 = 6 + 5
11 = 11
Answer:
88°
Step-by-step explanation:
Complementary angles have a sum of 90°, just do 90 - 2 and there's your answer.
Similar triangles that have a scale ratio other than 1 are not congruent triangles.
The true statement about the proportions of the sides is 
The scale ratio is given as: 5 : 2
And the corresponding sides are given as:
- AB and DE.
- BC and EF.
- CA and FD.
The above highlights mean that,

Hence, the true statement is
