Answer:

It will take them 4.44 days to decorate 2 homes.

Step-by-step explanation:

Given that:

Camilla can decorate a home in 5 days

Anne can complete a home in 4 days

Let,

x be the time taken by Camilla and Anne to decorate 1 home.

[tex]\frac{1}{Camilla's time}+\frac{1}{Anne's\ time} = \frac{1}{total\ time}\\[/tex]

[tex]\frac{1}{5}+\frac{1}{4}=\frac{1}{x}[/tex]

Taking LCM;

[tex]\frac{4+5}{20}=\frac{1}{x}\\\\\frac{9}{20}=\frac{1}{x}\\x=\frac{20}{9}[/tex]

Time taken by Camilla and Anne to decorate 2 homes = [tex]\frac{20}{9}*2=\frac{40}{9}[/tex]

Time taken to decorate Camilla and Anne 2 homes = 4.44 days

Hence,

It will take them 4.44 days to decorate 2 homes.

Answer:

y= -4/3x + 2

Step-by-step explanation:

y = mx +b

m is the slope and slope is rise over run, the points go up 4 but to the left three so thats -4/3

the b value is the y intercept and the y intercepts on this graph is +2

Answer:

D

Step-by-step explanation:

According to the Factor Theorem:

In order for a factor in the form of [tex](x-a)[/tex] to be a root for a function [tex]f(x)[/tex], [tex]f(a)[/tex] must be 0.

Our factor is [tex](x-1)[/tex].

Therefore, [tex]a=1[/tex].

So, we will evaluate [tex]f(1)[/tex] for all the choices.

Doing so, we can see that, starting from the top, we have:

[tex]\begin{aligned}f_1(1)&=-12\\ f_2(1) &=8 \\ f_3(1)&=24 \\ f_4(1)&=0 \end{aligned}[/tex]

The choice that yields 0 as an answer is D.

So, the function for which [tex](x-1)[/tex] is a real root is choice D.

Answer: Carla is 1/2x years old

Step-by-step explanation:

The present age of Carla in terms of x is (x - 2) / x.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Andrew's age = x

Blake's  age = x - 7

Carla's age = C

After 5 years,

Blake = (x - 7) + 5 = x - 7 + 5 = x - 2

Now,

x - 2 = 2C

C = (x - 2) / 2

Thus,

Carla's age is (x - 2) / 2.

Answer:

Divide all of them by 5.

30 g onions

16 g carrots

0.5 tablespoons of oil

130 g tomatoes

0.3 I vegetable stock (whatever this is)

I hope this helps! If there are calculation mistakes, I’m sorry because I did this all in my head...

30 onions

16 carrots

1/2 tablespoons of oil

130 grams of tomatoes

0.3 liters of vegatable stock

Since the recipe serves 5, you divide the ingredients by 5 to get the values needed for one portion:

150/5 = 30 onions

80/5 = 16 carrots

2.5/5 = 1/2 tablespoons of oil

650/5 = 130 grams of tomatoes

1.5/5 = 0.3 liters of vegatable stock

Answer:

x = 72

Step-by-step explanation:

Make the problem simpler by eliminating the fractional coefficients:

x-9= 1/4x + (1/4x + 12) + (1/4x - 3), when multiplied by 4, becomes:

4x - 36 = x + x + 48 + x - 12

Summing up all the x terms, we get:

4x - 2x - x = 48 - 12 + 36

Then x = 72

Step-by-step explanation:

The figure will be a rectangle when the diagonals AC and BD are the same length:

  AC = BD

  x +9 = 2x -11

  20 = x . . . . . . . add 11-x to both sides

ABCD will be a rectangle when x=20.
