There are numerous methods available to you, including, but not limited to,

completing the square

Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring.

Answer:

2.9 litres

2 14/15 litres

Step-by-step explanation:

To determine the amount of water Sam drinks in an hour, divide the total amount drunk by the number of hours

Amount drank in an hour = total litres drunk / time

$2\frac{1}{5}$ ÷ $\frac{3}{4}$

$\frac{11}{5}$ × $\frac{4}{3}$ = $\frac{44}{15}$ = 2 $\frac{14}{15}$ litres

La edad de 4 miembros de una familia suman 70. Mamá es 6 veces más grande que su hijo y 10 veces más grande que su hija. Papá es

3241004551 [841]

Answer:

3 5 30 32

Step-by-step explanation:

The question in English is

The age of 4 members of a family adds up to 70. Mom is 6 times bigger than her son and 10 times bigger than her daughter. Dad is 2 years older than Mom. How old are each of the family members? Write the result in ascending order and separated by spaces

Let

x----> Mon's age

y----> Son's age

z----> Daughter's age

w---> Dad's age

we know that

x+y+z+w=70 -----> equation A

x=6y ----> y=x/6 -----> equation B

x=10z ----> z=x/10 -----> equation C

w=2+x -----> equation D

substitute equation B, C and D in equation A and solve for x

x+(x/6)+(x/10)+(2+x)=70

Multiply by 60 both sides

60x+10x+6x+120+60x=4,200

136x=4,200-120

x=4,080/136

x=30 years

Find the value of y

y=x/6 -----> y=30/6=5 years

Find the value of z

z=x/10 ----> z=30/10=3 years

Find the value of w

w=2+x ----> w=2+30=32 years

Write the result in ascending order and separated by spaces
