Answer 1

Answer: 1 ) substitute the r in the equation for 1.2.6 (1.2)+7= ?...... multiply then add for. answer. 7.2+7= 14.22) since the miles Hanna runs is unknown it makes it n. Julie runs 3 miles less than twice hunny runs. Therefore it should be 2n-3.3) you would subtract the regular number from both sides first so 55-40= 15.. the equation would then be 5s=15 then you would divide both sides by 5...making s=3.4) you would add the sum of 8 to the product of 2 and y to get 24 so it should be 8+2y=24

Answers

So we have:
12 plastic cups total
3 green
4 red, 5 blue
the probability to have a non-green cup at the top of the stack is 9 out of 12, those are the non-green cups, so:
probability = 9/12 = 0.57 = 75%

Can someone help me solve this please?

Answers

to solve this you would need to create a fraction:

24/30 = ?/180

you would multiply 30 by 6 in order to get 180, and what you do to the denominator you must do to the numerator so you would get:

24/30 = 144/180

therefore your answer would be: b. 144

Ron had 20 apples. He used 2/5 of the apples to make pies. How many apples did Ron use for pies?

Answers

1/5 of 20 is 4.

2/5 of 20 is 8.

Therefore, Ron used 8 apples to make his pies.

Ron used 8 apples for his pies. 20/5=4 so 4 times 5 equals 20 and if you multply by 4 on one side you have to multiply by 4 on the other. And 4 times 2 equals 8.
