Answer:

Step-by-step explanation:

Cost of milk = $ m

Cost of bread = $ b

3m + 5b = 11   ------------------(I)

4m + 4b = 10       ----------------(II)

Multiply equation (I) by 4 and multiply equation (II) by (-3). Thus when you add, m will be eliminated and we can find the value of b

(I)*4            12m + 20b = 44

(II)*(-3)       <u>-12m - 12b = -30</u>   {Now add & m will be eliminated}

                             8b  = 14

b = 14/8

b = $ 1.75

Cost of a loaf of bread = $ 1.75

Plugin  the value of b in equation (I)

3m + 5*1.75 = 11

3m + 8.75 = 11

3m = 11 - 8.75

3m = 2.25

m = 2.25/3

m = $ 0.75

Cost of  one liter of milk = $ 0.75

Factorise and solve : x^3-x^2-4x+4
Alika [10]

(x - 1)(x - 2)(x + 2)

note that the sum of the coefficients 1 - 1 - 4 + 4 = 0

thus x = 1 is a root and (x - 1 ) is a factor

dividing x³ - x² - 4x + 4 by (x - 1)

x³ - x² - 4x + 4 = (x - 1)(x² - 4 ) (note (x² - 4 ) is a difference of squares )

x³ - x² - 4x + 4 = (x - 1)(x - 2)(x + 2)

(x - 1)(x - 2)(x + 2 ) =0

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

x + 2 = 0 ⇒ x = - 2

solutions are x = 1 or x = ± 2

How many 5-letter words can be made using exactly 5 of the letters from
kow [346]

The total number of ways by words are formed is 35 ways.

According to the statement

We have given that the 5 letters and we have to make word from them and the letters are repeated as equal to letters in given words.

And we have to find the possible ways.

So, The given words are:

TEXAS and MEXICO

Here X = 2 and E = 2 and all other words are one time used words.

We can find possible ways by use of combination and permutation.

So,

Total number of ways = 3C_{1} ^{5} + 2C_{2} ^{5}

here 3 because three letters are not repeatable and 2 letters are repeated for 2 times.

So,

Total number of ways = 3C_{1} ^{5} + 2C_{2} ^{5}

Total number of ways = 3(\frac{5!}{1!} ) + 2(\frac{5!}{2!*3!} )

Total number of ways = 3(5) + 2(10)

Total number of ways = 15 + 20

Total number of ways = 35.

So, The total number of ways by letters are formed is 35 ways.
