Radio tower had a special on rechargeable batteries. It sold AA for $1 and AAA for $0.75. It sold 42 batteries on a single day a
PIT_PIT [208]
AA = $1
AAA= $0.75

AA + AAA = 42

$1AA + $0.75AAA= $37

AA + AAA = 42
AA + AAA-AAA= 42- AAA
AA = 42- AAA

$1(42- AAA) + $0.75AAA= $37
$42 - AAA +0.75AAA = $37
$42 -0.25AAA= $37
$42-$42 -0.25AAA= $37 -$42
-0.25AAA= -5
-0.25AAA/-0.25 = -5/-0.25
AAA= 20

AA + AAA= 42
AA + 20 = 42
AA +20 -20 = 42-20
AA= 22

Check
$1AA + $0.75AAA= $37
$1(22)+ $0.75(20)= $37
$22 + $15 =$37
$37 = $37

One positive number is three more than twice another. If their product is 629, find the numbers.
sineoko [7]

Answer:

x = 17 and y = 37

Step-by-step explanation:

Let the numbers be x and y.

y = 3 + 2x

xy = 629

substituting y in the second equation we get

x(3+2x) = 629

3x + 2x^{2} = 629

2x^{2} + 3x - 629 = 0

Solving a quadratic equation by using its formula:

x = [-3 ±√(9-4(2)(-629)] / 4

x = [-3 ± √5041] / 4

x = [-3 ± 71] / 4

x = 17 and \frac{-37}{2}

Ignore the negative number in x and just use x = 17 in the first equation we get

y = 3 + 2(17) = 37

X4 - 4k3 + 4k Factor out the GCF of all three terms<br>​
Tatiana [17]

Answer:

Step-by-step explanation:

There isn't one. The first term is x^4.

The other two are stated in terms of k. There is nothing common here.

You can do 2 of the three. Terms 2 and 3 have a common factor of 4k, so what you can get is

x^4 - 4k(k^2 - 1)

Answer:

Cost of small box of oranges = 7

Cost of small box of oranges = 13

Step-by-step explanation:

Step 1)  Let the cost of small box of oranges = x

Let the cost of small box of oranges = y

Step 2)

Equation 1) Matt sells 3 small boxes and 14 large boxes for Php. 203

3x + 14y = 203 -------------------(I)

Equation 2) Ming sells 11 small boxes and 11 large boxes for Php. 220

11x + 11y = 220 ----------------(II)

Step 3:

Multiply equation (I) by 11 and equation (II) by (-3).

(I)*11              33x + 154y =  2233

(II)*(-3)         <u>-33x - 33y = -660 </u>            {Now add and x will be eliminated}

                           121y  = 1573

                               y = 1573/121

y = 13

Substitute y = 13 in equation (II)

11x + 11*13 = 220

11x + 143 = 220

        11x = 220 - 143

        11x = 77

          x = 77/11

x = 7
