[(4x + 15) / 5x)] = 1/2

Mathematics

One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:

<span>[(4x + 15) / 5x)] = 1/2  could be written as:

4x + 15        1
----------- =  ---
     5x           2

Then 8x + 30 = 5x

3x = -30,  and so     x = -10 (answer).  Be certain to check this answer through substitution!

Righty in equation in standard form using integers Y +1 equals 2/3 parentheses X +3 parentheses
Korolek [52]

Answer:

The standard for of the equation would be 2x + 3y = 3

Step-by-step explanation:

To start, we simply need to solve for the constant.

y + 1 = 2/3(x + 3)

y + 1 = 2/3x + 2

2/3x + y + 1 = 2

2/3x + y = 1

Now we need to multiply all the numbers by the largest denominator. This will make all the numbers integers. In this case, that number would be 3.

2x + 3y = 3

susan is arranging coffee mugs on shelves in her shop. she wanta each shelf to have the same number of mugs.she only wants one c
m_a_m_a [10]

This question belongs to greatest common factor.

49 = 7*7

56 = 7*8

So Greatest common factor = 7

Hence Susan can arrange 7 mugs on one shelf.

For 49 blue mugs, Susan can arrange 7 mugs in 7 shelves.

For 56 red mugs, Susan can arrange 7 mugs on 8 shelves.


Hence, 7 shelves are needed for BLUE mugs and 8 shelves are needed for RED mugs.
