heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr
Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr
so 24 problems can be done in 1 hr
Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done
and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem
ur answer is : 30 < 24x + 5 < 50 <==
Answer:
C. 52/289
Step-by-step explanation:
Ok so the total number of marbles is 6+4+2+5 (17).
The probability of picking an orange is 4/17 (because there are 4 orange blocks).
The probability of picking a block that isn't orange is 13/17.
Multiply those two numbers together, and you get: 52/289
1+4p
the answer cant be simplified any further than this.
-0.65
-3/8
2/4
5/16
I hope this is right, the negatives should go first because you are taking away, then positives

Answer: x = 10</h3>
Work Shown:
5x-6 = 44
5x-6+6 = 44+6 ... see note 1
5x = 50
5x/5 = 50/5 ... see note 2
x = 10
- note1: We add 6 to both sides to undo the -6
- note2: Divide both sides by 5 to undo the multiplication. Think of 5x as 5*x or "5 times x".
