<u>Answer:</u>
4
<u>Step-by-step explanation:</u>
We are given that a PE class has 12 boys and 8 girls. The teacher needs to divide in maximum number of teams so that each team has an equal number of boys and girls.
For this, we will factors of 12 and 8 and their greatest common factor.
12 = 4 × 3 = 2 × 2 × 3
8 = 4 × 2 = 2 × 2 × 2
The greatest common factor is 4, therefore the maximum number of teams with equal number of boys and girls is 4.
Answer:
x=-1
Step-by-step explanation:
Hey there!
The answer to your question is the third option: 2n + 7 = 5; n = -1
"twice a number increased by 7" would represent 2n + 7, and if it's equal to 5, it would be 2n + 7 = 5. That rules out the last option, and the second option. Now, we have to solve for "n":
2n + 7 = 5 Step 1: Write the equation.
2n = -2 Step 2: Subtract 7 from both sides.
n = -1 Step 3: Divide both sides by 2.
Therefore, "n" is equal to -1, and the third option would be correct.
Hope it helps! Have a great day, and good luck on your assignment!

Answer:
≈ 125.66 cm²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 8² × 
= 64π × = 8π × 5 = 40π ≈ 125.66 cm² ( to 2 dec. places )
