Answer:

DF = 38

Step-by-step explanation:

2x+2x-6=3x+5

4x-6=3x+5

x=11

DF = 3(11)+5

DF=33+5

DF=38

Candy counted to 600 by 6's, beginning with 6. Danny counted to 600 by 4's beginning with 4. How many the numbers that candy cou

KATRIN_1 [288]

Step-by-step explanation:

If we count for both numbers up to 36, we start seeing a pattern...

Candy: 6 12 18 24 30 36

Danny: 4 8 12 16 20 24 28 32 36

Every other number in Candy's counting is also counted by Danny. So here's what we'll do:

Divide 600 by 6

600/6 = 100

This is how many numbers Candy counted overall.

Divide the result by 2.

100/2 = 50

This is how many numbers Danny counted that were also numbers Candy counted.

Answer:

50 of the numbers that candy counted were also counted by Danny.

Three times a number subtracted by 3 is 20

nignag [31]

Answer:

3x - 3 = 20

Step-by-step explanation:

Times is a word that represents multiplication. A number can be represented by x.

3x - 3 = 20

Solving this:

3x - 3 = 20 1. Add 3 on both sides

3x = 23 2. Divide by 3 on both sides

x = 7 2/3
