Answer:
42
Step-by-step explanation:
x+(x+13)=71
2x+13=71
2x=71-13
2x=58
x=29 (alvin)
71-29=42 (elga)
You can order the fractions in order by using the denominator. If the denominator is the same, then use the numerator.
Penny. Dime means 10, nickel means 5, quarter is 25, and dollar means 1
If you make 6 items a day on day 30 you will have 180 items. This is just a simple division problem, 180/6=30
2= f/8
F is being divided by eight , when moving across equal sign the sign is opposite.
2 x 8 = f
16=f
The given identity tells you ...
.. (sum of numbers) * (sum of squares - product) = (sum of cubes)
Substituting the given information, you have
.. (sum of numbers) * (29 -10) = 133
Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7
The sum of the two numbers is 7.
