6.2÷(2x+1)=2 1/3 ÷4<br><br> find x
Norma-Jean [14]

You can look at all the fractions and form the least common multiple of their denominators.

6.2 = 6 1/5 has a denominator of 5

÷ (2x+1) puts (2x+1) in the denominator

2 1/3 has a denominator of 3

÷ 4 puts 4 in the denominator

These denominators have no common factors, so the least common multiple of 5, (2x+1), 3, and 4 is their product: 60(2x+1). Multiply the equation by this value.

\dfrac{6.2}{(2x+1)}\times 60(2x+1)=\dfrac{2\frac{1}{3}}{4}\times 60(2x+1)\\\\372=35(2x+1)\\\\372=70x+35\qquad\text{eliminate parentheses}\\\\337=70x\qquad\text{subtract 35}\\\\x=\dfrac{337}{70}\qquad\text{divide by the x coefficient}

The solution is x = 337/70.

What is number 7?? Plz answer
lara31 [8.8K]
Area of rectangle = length * width

A = (2 2/9 yd) * (3 2/5 yd)

Convert both mixed numerals into fractions.

A = (20/9 yd) * (17/5 yd)

A = (20 * 17)/(9 * 5) yd^2

A = (4 * 17)/(9) yd^2

A = 68/9 yd^2

A = 7 5/9 yd^2

ziro4ka [17]

Answer:

Part A:  A ratio of 2:1  means that he uses<u><em> </em></u><u><em>2 cups of yellow paint for each cup of blue paint.</em></u>

-------------------------------------------------------------------------------------------------

Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:

2/1 = 1/x

x = (1*1) / 2

x = 1/2

<u><em>For each cup of yellow paint, Greg should add 1/2 cup of blue paint.</em></u>

<u><em></em></u>
