2x + 18 = 40
Twice a number and 18 is 40.
What is: 5x+9= 58
What is the probability of rolling a sum of 12 with 2 dice?
What is: An example, 2x + 3 = 7
Write a mathematical equation that includes two constants and a variable.
+ 12. + 12
8x/8 = 72/8
x = 9
Show work to both sides of the equation and solve: 8x-12=60
The theoretical probability of blue is 1/3.
The experimental probability of 3/3.
Your spinner has 3 different colors: Red, Blue, Yellow. You spin the spinner three times and you land on all of your spins on Blue. Is the experimental probability similar or different to the theoretical?
12 subtracted from the product of a number and 4 is 4
I brought 100rm to the pet store to buy hamsters and supplies and I used it all. I bought 2 hamsters. I spent 34 rm to buy a hamster cage. I also bought food that was the same price as one hamster. How much was one hamster?
If you are rolling a 10 sided-die, what is the probability to roll an odd number?

One increased by one increased by a number multiplied by eight equals thirty-four.
x = 2
If Alice bought 10 pencils and 5 pens, each pen cost 6RM and she paid 50RM total, how much is one pencil?
There are 65 chips total and there are 15 red chips. Therefore, there are 50 non-red chips. The probability is 50/65=10/13= 77%
I have 20 yellow chips, 30 blue chips, and 15 red chips. If I pick one chip randomly out of a total 65 chips, what is the probability of not picking red chips?
(n+-6)/10 = 50
The sum of a number and the opposite of 6, divided by 10 is the same as 50.
Smallest #: x
First Middle #: x+1. Second Middle #: x + 2.
Biggest #: x+ 3
x + x + 1 + x + 2 + x + 3 = 70
4x + 6 = 70
- 6 - 6
4x = 64
x = 16
Smallest #: 16
First Middle #: 17
Second Middle #: 18
Biggest #: 19
Four consecutive numbers add up to 70. What is the biggest number?
The more times you do the experiment, the closer the Experimental Probability is to the Theoretical Probability.
Experimental Probability and Theoretical Probability can be very different from each other. When will they be most similar?
