A recipe has a ratio of 2 cups of sugar to 6 cups of flour. How many cups of flour are used for each cup of sugar in the recipe?

10 quarters 17 dimes 40 nickels 15 pennies answer
Oliga [24]

If the given quantities are 10 quarters 17 dimes 40 nickels 15 pennies then the total money would be 6.35 dollars.

<h3>What is the fundamental principle of multiplication?</h3>

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Quarters are worth .25 of a dollar

10 x .25 = 2.5

Dimes are worth .10 of a dollar

17 x .10 = 1.7

Nickels are worth .05 of a dollar

40 x .05 = 2

Pennies are worth .01 of a dollar

15 x .01 =  0.15

Add this together

2.5 + 1.7 + 2 + 0.15

= 6.35

(x+3)(x-5)-(4x+1)(1-4x)=17x^
Greeley [361]

Answer: \boxed{Sol=\{\dfrac{7}{4} \}}\\

I suppose 17x^ means 17x².

and that we must solve the equation.

Step-by-step explanation:

(x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\
