Cost for a carnation is $0.75

Step-by-step explanation:

Let,

Rose = x

Carnation = y

According to given statement;

8x+5y=31.75   Eqn 1

x+3y=5.75   Eqn 2

Multiplying\ Eqn\ 2\ by\ 8\\8(x+3y=5.75)\\8x+24y=46 \ \ \ Eqn\ 3\\Subtracting\ Eqn\ 1\ from\ Eqn\ 3\\(8x+24y)-(8x+5y)=46-31.75\\8x+24y-8x-5y=14.25\\19y=14.25\\Dividing\ both\ sides\ by\ 19\\\frac{19y}{19}=\frac{14.25}{19}\\y=0.75

Cost for a carnation is $0.75

Oksana_A [137]

Answer:

4 cm

Step-by-step explanation:

The midpoint segment has length ...

... L = AB/2 + BC + CD/2 = 16 cm

The entire segment has length ...

... AD = AB + BC + CD = 28 cm

If we subtract AD from 2L, we have ...

... 2L - AD - 2L = 2(AB/2 +BC + CD/2) - (AB +BC +CD) = 2(16 cm) -28 cm = 4 cm

... AB +2BC + CD -AB -BC -CD = 4 cm . . . . remove parentheses

... BC = 4 cm . . . . simplify

Maria wrote the equation log(x/2)+log(20/x^2)=log8. What is the solution to Maria's equation?
Fed [463]
The solution is x=5/4.

We use the properties of logs to rewrite the equation:
\log[(\frac{x}{2})(\frac{20}{x^2})]=\log8
\\
\\\log(\frac{20x}{2x^2})=\log8
\\
\\\log(\frac{10}{x})=\log8

Get all of the logs on the same side of the equation y subtracting log 8:
\log(\frac{10}{x})-\log8=\log8 - \log8
\\
\\\log(\frac{10}{x})-\log8=0

Use the properties of logs to rewrite:
\log(\frac{10}{x}\div8)=0
\\
\\\log(\frac{10}{x}\div\frac{8}{1})=0
\\
\\\log(\frac{10}{x}\times\frac{1}{8})=0
\\
\\\log(\frac{10}{8x})=0

Exponentiate:
10^0=\frac{10}{8x}
\\
\\1=\frac{10}{8x}

Multiply both sides by 8x:
1*8x = (10/8x)*8x
8x=10

Divide both sides by 8:
8x/8 = 10/8
x = 10/8 = 5/4
