Let x = cost of one cheese pizza.
Let y = cost of one pepperoni pizza.
Set up a system of equations.
6x + 7y = 153.50
2x + 2y = 47.00.
Multiply the second equation by -3
6x + 7y = 153.50
-6x - 6y = -141.00.
Add the equations together
y = $12.00.
Plug 12 into one of our original equations.
2x + 2(12) = 47.
Simplify the left side.
2x + 24 = 47.
Subtract 24 from each side.
2x = 23.
Divide each side by 2
x = $11.50
In conclusion, one pepperoni pizza costs $12.00
Answer:
1 meter equals 100 centimeters, to find out how many centimeters you want to take 0.24*100= 2.4,
Therefore; the computer tablet is 24 centimeters long.
So that is equal to 180 miles per 2 hours which is 90 miles per hour if each hour has the same m/hr rate.
You can set up a proportion:
let x = number of miles per hour
cross multiply and you get
2x=180
divide both sides by 2 and you get
x=90
so you get the same answer both ways,
90 miles per hour
Hello,
In this pattern you can notice that the numbers and letters alternate, 1 by 1. Also, from each number to the next, 3 is added. (4 + 3 = 7, 7 + 3 =10, 10 + 3 = 13). For the letters, it goes in alphabetical order with two letters being skipped between each letter. (D, G, J).
Based on the number letter pattern, the last value is a number indicating a letter is next. Now, we just follow the same "skip two" letters pattern to get from J to M.
I believe M is the answer.
Hope this helps!
