3 times x equals to 646
3x=646
Given:
ft and
ft.
![P=2L+2W](https://tex.z-dn.net/?f=P%3D2L%2B2W)
To find:
The value of P.
Solution:
We have,
![P=2L+2W](https://tex.z-dn.net/?f=P%3D2L%2B2W)
Substituting
and
, we get
![P=2\times 2\dfrac{1}{2}+2\times 3\dfrac{2}{5}](https://tex.z-dn.net/?f=P%3D2%5Ctimes%202%5Cdfrac%7B1%7D%7B2%7D%2B2%5Ctimes%203%5Cdfrac%7B2%7D%7B5%7D)
![P=2\times \dfrac{2(2)+1}{2}+2\times \dfrac{3(5)+2}{5}](https://tex.z-dn.net/?f=P%3D2%5Ctimes%20%5Cdfrac%7B2%282%29%2B1%7D%7B2%7D%2B2%5Ctimes%20%5Cdfrac%7B3%285%29%2B2%7D%7B5%7D)
![P=2\times \dfrac{5}{2}+2\times \dfrac{17}{5}](https://tex.z-dn.net/?f=P%3D2%5Ctimes%20%5Cdfrac%7B5%7D%7B2%7D%2B2%5Ctimes%20%5Cdfrac%7B17%7D%7B5%7D)
![P=5+\dfrac{34}{5}](https://tex.z-dn.net/?f=P%3D5%2B%5Cdfrac%7B34%7D%7B5%7D)
Taking LCM, we get
![P=\dfrac{5(5)+34}{5}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B5%285%29%2B34%7D%7B5%7D)
![P=\dfrac{25+34}{5}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B25%2B34%7D%7B5%7D)
![P=\dfrac{59}{5}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B59%7D%7B5%7D)
![P=11\dfrac{4}{5}](https://tex.z-dn.net/?f=P%3D11%5Cdfrac%7B4%7D%7B5%7D)
Therefore, the value of P is
ft.
Answer:
534
Step-by-step explanation:
multiply 13.45 by 40 and you will get 534
Answer:
13
Step-by-step explanation:
Not sure, i'm sorry
should be the same logic as
a=b
b=c
a=c
X = amount of seeds.
y = amount of dried fruits.
we know the snack mix contains both, and we know is 10oz, thus
x + y = 10, whatever ounces "x" and "y" are.
how much is it for "x" ounces if each one costs $1.5? well is just 1.5*x or
1.5x.
how much is it for "y" ounces if each one costs $2.5? well is just 2.5*x or
2.5x.
the mix contains 10 ounces, each of which costs $2.2 each, how much will it be then for 10 oz? well, is just 10 * 2.2, or $22.
since the whole 10 oz snack mix costs 22 bucks, then
1.5x + 2.5y = 22.
![\bf \begin{cases} x+y=10\implies \boxed{y}=10-x\\ 1.5x+2.5y=22\\ -------------\\ 1.5x+2.5\left( \boxed{10-x} \right)=22 \end{cases} \\\\\\ 1.5x+25-2.5x=22\implies -x+25=22\implies 3=x](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Bcases%7D%0Ax%2By%3D10%5Cimplies%20%5Cboxed%7By%7D%3D10-x%5C%5C%0A1.5x%2B2.5y%3D22%5C%5C%0A-------------%5C%5C%0A1.5x%2B2.5%5Cleft%28%20%5Cboxed%7B10-x%7D%20%5Cright%29%3D22%0A%5Cend%7Bcases%7D%0A%5C%5C%5C%5C%5C%5C%0A1.5x%2B25-2.5x%3D22%5Cimplies%20-x%2B25%3D22%5Cimplies%203%3Dx)
how many ounces of dried fruit is there anyway? well, y = 10 - x.
