Answer:
3 7/18
Step-by-step explanation:
2 1/6 + 1 2/9 (- cancels with the - to give us +)
Convert to simple fraction: 13/6 +11/9
Find the common denominator: 13x 3/6x3 + 11 x 2/9 x 2
39/18 + 22/18
Now that the denominators are same, conduct the given operation.
39 + 22/ 18
61/18
Convert into mixed fraction: 3 7/18
Final answer: 3 7/18
You need to find "two-fifths of 30." Of here means multiplication:
![\begin{aligned}\dfrac{2}{5}\cdot 30 &= \dfrac{2}{5}\cdot\dfrac{30}{1}\\[0.5em] &= \dfrac{60}{5}\\[0.5em] &= 12\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%2030%20%26%3D%20%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%5Cdfrac%7B30%7D%7B1%7D%5C%5C%5B0.5em%5D%20%26%3D%20%5Cdfrac%7B60%7D%7B5%7D%5C%5C%5B0.5em%5D%20%26%3D%2012%5Cend%7Baligned%7D)
There are 12 athletes in the club.
Add 14 to both sides
2/3p=p+27
Subtract p from both sides
-1/3p= 27
Multiply both sides by -3
p= -81
Final answer: p=-81
Just multiply 42 by 10 and that gives you 420 , so the real car has a length of 420cm or 4.2 metres :)
6 + y - 3
We cans simplify that to:
y + 3
The coefficient is the number in front of the variable. y is nothing by 1y. So the coefficient is 1.
The variable is y.
The constant is the number without the variable, which is 3.
The answer you are looking for is 1, which is the coefficient.
