5x-4=2x+8
+ 4 +4 Add 4 to both sides
5x=2x+12
-2x -2x Subtract 2x from both sides
3x=12
/3 /3 Divide by 3 on both sides
x=4

5x - 4 =2x +8
First you would subtract 2x on both sides
3x-4=8
Then add 4 on both sides
3x=12
Then divide by 3 on both sides
X=4

Answer:

n = 5
m = 12
m= -14
y =30

Step-by-step explanation:

$n -8 =-3\\\\Collect\:like\:terms\\n = -3+8\\\\Simplify ; -3+8 = 5\\\\n =5$

$-2m=-24\\\\Divide\: both \:sides\:of\:the\:equation\:by\:-2\\\\\frac{-2m}{-2} = \frac{-24}{-2} \\\\Simplify ; -2m/-2 = m , -24/-2 = 12\\\\m =12$

$\frac{m}{2}=-7\\\\Cross\:Multiply\\\\m\times 1 = 2\times -7\\\\m = -14$

$\frac{2}{3}y=20\\ \\\frac{2}{3} y = \frac{20}{1} \\\\Cross\:Multiply\\\\2y\times 1 = 3\times 20\\\\2y = 20\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2y}{2}=\frac{60}{2}\\\\Simplify\\y = 30$

You have a shelf that holds 25 1/2 pounds. What is the most number of 1 1/4 pound books that the shelf can hold?

patriot [66]

Answer:

20 books

Step-by-step explanation:

given that the shelf can hold 25 1/2 lbs (i.e 25.5 lbs), and that each book weighs 1 1/4 ln (i.e 1.25 lbs)

number of books which the shelf can hold

= weight that the shelf can hold ÷ weight of each book

= 25.5 ÷ 1.25

= 20.4 books

because having 0.4 of a book (i.e part of a book) would not be very feasable, we have to round the number of books down to the nearest whole number)

20.4 books rounded down to nearest whole number = 20 books (answer)

3/4 х36 how do I solve it

ANEK [815]

Hi there!

Convert 36 into 35 and 4/4 since if it is just a number, it can’t be multiply by 3/4.

$36= 35 \frac{4}{4}$

Multiply both fractions now but also turn 35 4/4 into a mixed number:

$36=\frac{144}{4}$

$\frac{3}{4} x \frac{144}{4}= \frac{27}{1} = 27$

Final Result: 27
