Alex sold 330 candy bars, milk chocolate candy bars sold for $2 each and white chocolate candy bars sold for $3 each. Alex sold
Alinara [238K]

Answer:

<em>Alex sold 330 white chocolate bars</em>

Step-by-step explanation:

let the milk chocolate candy be x and the white chocolate candy be y. then

then 2x+3y=990----1)

x+y=330-----2)

from eq 2) ⇒ x=330-y---------3)

Putting eq 3 in eq 1

2(330-y) +3y=990

660-2y+3y=990

y=990-660=330-----------4)

Putting eq4 in eq1

2x+3(330)=990

2x+990=990

2x=990-990

2x=0

x=0---------------------------5)

Write 9.753 in words
vlabodo [156]
Hey there! :D

When you write out decimals, you use words that end with 'ths'. And you use the smallest digit's place to name the whole decimal. 

For example,

.1 = one-tenths  .25= twenty hundreths .345= three hundred and forty five thousandths

9.753= Nine and seven hundred fifty-three thousandths. 

I hope this helps!
