Answer:
La familia bebió:
2 botellas de 1.5 L = 2*1.5L = 3L
5 botellas de 1/4 de litro = 5*(1/4 L) = 5/4 L
4 botellas de 1/4 de litro = 4*(1/4 L) = 1 L
Sumando eso, tenemos:
3 L + (5/4) L + 1L = 4L + 5/4 L = (16/4) L + 5/4 L = (21/4) L.
21/4 Litros tomaron en total.
¿podemos directamente sumar y restar fracciones de distintos denominadores?
No, tenemos que tener el mismo denominador para sumar o restar.
Answer:
<u>x = 62 words</u>
Explanation:
→ <em>We write the data problems. </em>
372 words .............6 minutes
→ We must find: <em>What's Cynthia typing rate in words per minute?</em>
372 words .............6 minutes
x words ..................1 minute
x = 372 words * 1 minute/ 6 minutes
<u>x = 62 words</u>
Solve Let's solve your equation step-by-step.5+3.9x−8.15x25x=0
Step 1: Simplify both sides of the equation.−0.326x2+3.9x+5=0
Step 2: Use quadratic formula with a=-0.326, b=3.9, c=5.x=−b±sqrt(b2−4ac)2ax=−(3.9)±sqrt((3.9)2−4(−0.326)(5))2(−0.326)x=−3.9±sqrt(21.73)−0.652x=−1.1680135096973403,13.131203693746418Answer:<span>x=

Answer:
of oil.
Step-by-step explanation:
Firstly, you need to find the LCD (lowest common denominator), this can be done by factoring the denominators and knowing the multiples.
In this case, you can see that 2 is a factor of 8 so we can simply multiply 
so that the denominator is 8:
8 ÷ 2 = 4
Now the fractions can be added easily:
= of oil.
Hope this helps!
