Ellen is making smoothies. The recipe calls for 1 and 1/4 cups of strawberries. How many cups of strawberries, written as a frac

BartSMP [9]

Answer:

the number of cups of strawberries needed in the recipe is ⁵/₄

Step-by-step explanation:

Given;

cups of strawberries needed for the smoothies = 1 and 1/4 cups

To obtain the number of cups of strawberries needed in the recipe as a single fraction, the given mixed fractions will be converted into an improper fraction.

Note: Improper fractions are always greater than 1

Number of cups of strawberries $=1 + \frac{1}{4} = \frac{4 + 1}{4} = \frac{5}{4}$

Therefore, the number of cups of strawberries needed in the recipe is ⁵/₄

I need help. What does n equal.<br> <img src="https://tex.z-dn.net/?f=5n%5E%7B2%7D%3D7n-2" id="TexFormula1" title="5n^{2}=7n-2"

Ede4ka [16]

Answer:

$\boxed{\sf n= \dfrac{2}{5} ,\: n=1}$

Step-by-step explanation:

$\rightarrow 5n^2 = 7n -2$

$\rightarrow 5n^2 - 7n +2=0$

$\rightarrow 5n^2 - 5n -2n+2=0$

$\rightarrow 5n(n - 1) -2(n-1)=0$

$\rightarrow (5n-2)(n-1)=0$

$\rightarrow 5n-2= 0,\: n-1=0$

$\rightarrow 5n= 2,\: n=1$

$\rightarrow n= \dfrac{2}{5} ,\: n=1$
