Could you solve it What is _____+______+______=30 Using 1,3,5,7,9,11,13 ,15 what are the numbers ​
wariber [46]

Answer:

We want to solve:

___ + ___ + ____ = 30

using the numbers:

1, 3, 5, 7, 9, 11, 13, 15.

Now, 30 is an even number.

And the given numbers are all odd.

A random even number is written as:

2*n  (where n is an integer)

A random odd number is written as:

2*k + 1 (where k is an integer)

If we add 3 odd numbers, we get:

(2*k + 1) + (2*c + 1) + (2*j + 1) = 2*(k + c + j) + 3

= 2*(k + c + j + 1) + 1

(k + c + j + 1) is an integer, then we can write this as p

then the sum of 3 odd numbers can be written as:

2*p + 1

This means that the sum of 3 odd numers is always an odd number.

Then we can not find 3 odd numbers such that their sum is equal to 30.

if instead, we could use 4 numbers, like:

___ + ___ + ___ + ___ = 30

Then we could select:

15, 1, 5 and 9.

because:

15 + 1 + 5 + 9 = 15 + (1 + 5) + 9 = 15 + 6 + 9 = 15 + (6 + 9) = 15 + 15  = 30

A business orders 330 flowers for their employees on Valentine's Day. Roses cost
hjlf

Answer:

Roses = x = 100

Carnations = y = 110

Lilies = z = 120

Step-by-step explanation:

Roses = $4.50

Carnations = $3.00

lilies = $2.50

Total flowers ordered = 330

Total cost = $1,080

Let

Roses = x

Carnations = y

Lilies = z

x + y + z = 330

4.50x + 3y + 2.50z = 1080

There are 20

more lilies than roses

z = x + 20

Substitute z = x + 20 into the equations

x + y + (x + 20) = 330

4.50x + 3y + 2.50(x + 20) = 1080

x + y + x + 20 = 330

4.50x + 3y + 2.50x + 50 = 1080

2x + y = 330 - 20

7x + 3y = 1080 - 50

2x + y = 310 (1)

7x + 3y = 1030 (2)

Multiply (1) by 3

6x + 3y = 930 (3)

7x + 3y = 1030 (2)

Subtract (3) from (2)

7x - 6x = 1030 - 930

x = 100

Substitute x = 100 into (1)

2x + y = 310

2(100)+ y = 310

200 + y = 310

y = 310 - 200

= 110

y = 110

Substitute the value of x and y into

x + y + z = 330

100 + 110 + z = 330

210 + z = 330

z = 330 - 210

= 120

z = 120

Roses = x = 100

Carnations = y = 110

Lilies = z = 120
