To do this problem, we must first distribute the 13 and 14 into the parenthesis.
<span>13(9−6m)+14(12m−8)
117 - 78m + 168m - 112
To combine like terms, we can add/subtract terms that have an "m" together and then we can add/subtract terms that do not have "m" together.
117 - 112 = 5
and
168m - 78m = 90m
So our final sum is 5 + 90m</span>
Answer:
Step-by-step explanation:
Remark
You can do this with just 1 unknown.
John = x
Tom = 2x
Solution
x + 2x = 27 Combine the left
3x = 27 Divide by 3
3x/3 = 27/3
x = 9
Conclusion
John invited 9
Tom invited 18
Answer: Hello!
In this problem you can chose 3 options:
the type of cone, the first flavour, and the second flavour.
a) In how many different ways can your order one cone and two scoops of ice cream?
You have 5 options for cones, 9 options for the first ball of ice cream, and 9 options for the second ball of ice cream (because you can repeat flavour) then the total number of combinations is the product of this 3 numbers, this is:
5*9*9 = 405 combinations
b) Here we cant order the same flavour of ice cream, then:
we still have 5 options for cones, 9 options for the first ball of ice cream, and this time 8 options for the second ball ( because we need to remove the flavour that we picked in the first ball of ice cream) then the number of combinations is:
5*9*8 = 360 combinations.
You are investing $2,000 fro 3 months and the APR is 4% so you will get one quarter of the APR for a year. For the year 4% interest is $2,00 x .04 or $80 for the year. # months is 1/4 of a year so divide $80 by 4 to get the interest fro 3 months which is 20 so the answer is B.
