How to solve -6x + 3 = 4x + 11

Answers

Answer 1
Answer: Add 6 on both sides

-6x + 6x + 3 = 4x + 6x + 11
3 = 10x + 11

Subtract 11 on both sides

3 - 11 = 10x + 11 - 11
-8 = 10x

Divide by 10 on both sides

-8/10 = 10x/10
-8/10 = x

Simplify

x = -8/10
x = -4/5
x = -0.8
Answer 2
Answer: Add 6x to both sides

3 = 10x + 11

Subtract 11 on both sides

-8 = 10x

Divide by 10 on both sides

x = -8/10 = -4/5

Jan buys 12 pens for 10$. Each pen costs the same amount of money. Write a proportion to find the number of pens Jan can buy $15. Then solve your proportion for the number of pens.

Answers

You can write the proportion as 2 equal fractions or as two equal ratios.
(12)/(10) = (x)/(15)   or   12 pens:$10 = x pens:$15

You can buy x pens for 15 dollars. One way to find x is by cross multiplying the fractions.

10x=12×15
10x=180
-----  -----
10    10 
x=18

You can buy 18 pens for $15.

describe two ways you could evaluate 37% of the sum of 27.6 and 15.9. tell witch method you would use and why

Answers

The percentage of 37% of the sum of the numbers 27.6 and 15.9 will be

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The first method

Find the sum of two numbers,

27.6 + 15.9 = 43.5

37% of 43.5 will be as,

0.37 x 43.5 = 16.095

The second method →

Find the 37% of 27.6 as

0.37 x 27.6 = 10.212

Find the 37% of 15.9 as

0.37 x 15.9 = 5.883

Add both numbers as

10.212 + 5.883 = 16.095

The easiest method is method 1 because it is fewer in steps.

Hence "The percentage of 37% of the sum of the numbers 27.6 and 15.9 will be 16.095.
