Answer:
40 bottles of juice
60 bottles of water
Step-by-step explanation:
let w represent water, let j represent juice. set up a system of equations:
w+2j=140
w+j=100
isolate the w by itself on the bottom equation:
w=100-j
solve the top equation by substitution, substituting 100-j for w:
w+2j=140
100-j+2j=140
100+j=140
j=40
this means that they bought 40 bottles of juice.
to find the amount of bottles of water the bought, substitute 40 for j in either of the equations (i did it in the bottom one, because it's easier):
w=100-j
w=100-40
w=60
so, they bought 60 bottles of water.
You can write an improper fraction and mixed numbers
Answer:
a
Step-by-step explanation:
The question ask to convert the said fraction in to its simplest form, according the mathematical law of fraction, in converting the said fraction in to its simpler form, you must first get the Greatest Common Factor of the numerator and the denominator and base on that, the simplest form of it is -3/4. I hope this would help
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction
This is the order of how to solve the problems. For this problem, we can start with parentheses since it has that in this equation.
5 x 6 ÷ (5)
The next step is to do Multiplication.
30 ÷ 5
Finally Division.
6
This is your final answer.
Hope that helps!
