Answer:
x^4-9x^2+26x-24
Step-by-step explanation:
She is going to practice piano for 80 minutes. First you want to divide the number of minutes in the lesson by 5 to find how many times 5 minutes goes by in 20 minutes. Next you want to multiply your answer for that, which should be 4, by the amount she wants to practice. So you do 4 x 20, and get 80 minutes total.
Answer: 3 Y=3
Step-by-step explanation:
Y×3=9
3×3=9
You can also check this by rearranging it and dividing 9 by 3.
9÷3=3.
This works for any similar problem.
Example:
Y×4=12 Y=? Y=3
Rearrange it and divide 12 by 4.
12÷4=Y
12÷4=3
So Y×4=12 because 3×4=12
Hope this helps!
5r + 2t = c
In this equation, 'r' represents the number of rose bushes, 't' represents the number of tomato plants, and 'c' represents the total cost.
C = 2 pi r
Since it is traveling around the circle 3 times we will use:
2 * 3 * 3.14 * 80
Total distance traveled = 1507.2 ft
