Using equation, He bought 3 boxes of ballpoint pens and 15 boxes of felt-tip pens
<h3>How to find the boxes of each type of pen using equation?</h3>
let
x = number of boxes of ballpoint pens
y = number of boxes of felt-tip pens
Therefore, the situation will form an equation.
x = 5y
Hence,
4.33x + 3.42y = 75.21,
4.33(5y) + 3.42y = 75.21
21.65y + 3.42y = 75.21
25.07y = 75.21
y = 75.21 / 25.07
y = 3
x = 5(3) = 15
Hence, he bought 3 boxes of ballpoint pens and 15 boxes of felt-tip pens

Answer:
4/3
Step-by-step explanation:
First you need to change 8 to 8/1
And then multiply 1/6 by 8/1
(1)(8)=8
(6)(1)=6
So you are left with 8/6 which simplifies to 4/3 or 1 1/3
Answer: 3/8x
To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple of the denominators. This number is same as the least common denominator .You can then write each term as an equivalent fraction with the same LCD denominator.
she needs 75 =10h=money per hour (so h=hour) +5= automatic tip
75=10h+5
75-5=10h+5-5
70=10h
70/10=10h/10
7=h
