Amanda and Ndiba are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodi
Mumz [18]

Answer:

daffodil = $13 Tulip = $7

Step-by-step explanation:

6t + 12d = 198

7t + 6d = 127

6t = 198 - 12d

t = 33 -2d

substitute

7(33-2d) + 6d = 127

231 -14d +6d = 127

- 8d = -104

d =13

6t + 12(13) = 198

6t +156 = 198

6t = 42

t = 7

QUICK!! 18x^2+21x-60=0 pls give me the steps as well
Anton [14]

Answer:

<h2>x1 =  -  \frac{5}{2}</h2>

x2 =  \frac{4}{3}

Step-by-step explanation:

18 {x}^{2}  + 21x - 60 = 0

Divide both sides of the equation by 3

6 {x}^{2}  + 7x - 20 = 0

Write 7x as a difference

6 {x}^{2}  + 15x - 8x - 20 = 0

Factor out 3x from the expression

3x(2x + 5) - 8x - 20 = 0

Factor out -4 from the expression

3x(2x + 5) - 4(2x + 5) = 0

Factor out 2x + 5 from the expression

(2x + 5)(3x - 4) = 0

When the product of factors equals 0 , at least one factor is 0

2x + 5 = 0

3x - 4 = 0

Solve the equation for X

2x + 5 = 0

Move constant to R.H.S and change its sign

2x = 0 - 5

Calculate the difference

2x  =  - 5

Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{ - 5}{2}

Calculate

x 1=  -  \frac{5}{2}

Again,

3x - 4 = 0

Move constant to RHS and change its sign

3x = 0 + 4

Calculate the sum

3x = 4

divide both sides of the equation by 3

\frac{3x}{3}  =  \frac{4}{3}

Calculate

x 2=  \frac{4}{3}

Hope this helps..

Best regards!!

What's the answer -5+ 8x - 9 = 3x+3)​
Vika [28.1K]
We collect like terms
8x - 3x = 3 + 5 + 9
This is bcos if a (-) sign crosses the equals sign it becomes a (+), and if a (+) sign crosses the equals sign it becomes (-)
We the have
5x = 17
Divide both sides by 5
x = 17/5
x = 3.4

A copy machine makes 136 copies in 4 minutes and 15 seconds. How many copies does it make per minute?
Dahasolnce [82]

Answer:

The copy machine makes 32 copies per minute.

Step-by-step explanation:

Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:

15 seconds = 0.25 minutes

136 / 4.25 = X

32 = X

Therefore, the copy machine makes 32 copies per minute.
