What is the standard form of x/4 - y/3 =1 and 5/x - 2/y=7.

Answers

You can multiply both sides by a number that will get rid of the denominators. For ex. you can multiply the first equation by 12 because 4 and 3 both go into 12 evenly. MAKE SURE YOU MULTIPLY THE OTHER SIDE BY 12 AS WELL! Therefore, 12(x/4) - 12(y/3) = 12(1), or 3x - 4y = 12

Fourteen is 28% of what number?
A. 7
B. 50
C. 14
D. 42

Answers

Fourteen is 28% of B) 50

Why, you ask? Let's see -

Let the unknown number be n, for 'number'.

Let's put the unknown n next to 28%

.28n% = 14

(Think, what times .28 equals 14? Look below to find out! ↓ )

Let's now do the opposite of the actual equation - divide the two known numbers by each other -

.28 ÷ 14 = 50

When in doubt, check your answer:

To check this, we would do the opposite - Multiplication

Multiply .28 by 50 to get 14 (At least you should get 14)

.28 × 50 DOES EQUAL 14! We were right! :D

I need help on my math homework.A hairdresser is considering ordering a certain shampoo. Company A charges $4 per 8-oz bottle plus a $10 handling fee per order. Company B charges $3 per 8-oz bottle plus a $25 handling fee per order. How many bottles must the hair dresser buy to justify using Company B? (Answer in a complete sentence.)

I don't know what justify using company B means. Can someone help me?

Answers

hi tissuebox,

let x= the number of bottles the customers buys

first, lets consider how many bottles the customer must buy for the price to be the same no matter which company.

4x+10=3x+25
.
.
.
x=15, so at 15 bottles, the cost is the same for either company. At this point you look at x=16, one bottle higher, to compare costs, seeing that for company A this is $74 while for company B this is $73, so at 16 bottles company B is cheaper
