Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends a
Natasha_Volkova [10]

Answer:

16 friends

Step-by-step explanation:

Right at the beginning, you can take the 2 chocolates Jack was left with out of the 50 chocolates Jack had at the beginning. That equals 48 chocolate bars, so we know that Jack gave his friends a total if 48 chocolates

50 - 2 = 48

Now that you have the number 48, you are really close to the answer.

If you know that he gave each if his friends 3 chocolates, you can make that into an equation and put it into a calculator. That would look like this:

48 \div 3 = 16

The reason you do 48 ÷ 3 is because Jack divided his 48 chocolates into groups of 3 to give to each of the other kids.

You get the answer 16, which means the answer is 16 kids at his friend's birthday party.

Find d and the measure of each side of equilateral triangle KLM if KL=d+2, LM=12-d, and KM=4d-13
fiasKO [112]

Answer:

all sides are 7 units

Step-by-step explanation:

Since the triangle is equilateral then all 3 sides are equal in length

equate any 2 sides and solve for d

KL = LM

d + 2 = 12 - d ( add d to both sides )

2d + 2 = 12 ( subtract 2 from both sides )

2d = 10 ( divide both sides by 2 )

d = 5

KL = d + 2 = 5 + 2 = 7

LM = 12 - d = 12 - 5 = 7

KM = 4d - 13 = (4 × 5) - 13 = 20 - 13 = 7
