x is the 1st number, y is the 2nd number, z is the 3d number.

x+y+z = 2

x - y + z= -2

x - z = y +22 -----> x-y-z=22


x+y+z = 2

<u>x - y + z= -2</u>

2x + 2z =0

x + z = 0

x = -z


x - y + z= -2 and x = -z

-z - y + z = -2, y =2


x-y-z=22 and x = -z, and y = 2 -----> x -2 +x = 22 --->2x = 24 ----> x = 12

x= -z -----> z = - 12

Daisy made bread. The equation B = 4f shows the number of loaves of bread baked based on the amount of flour used, where B is th
Fynjy0 [20]

Answer:

k=4

Step-by-step explanation:

-The constant of proportionality  is defined as the ratio between two directly proportional variables.

-Given that B=4f

#The constant of proportionality is calculated as:

- the equation can be written in the form y=kx,

where y varies directly with x and k is the constant of variation:

y=kx\\\\k=\frac{y}{x}\\\\\therefore  B=4f\\\\\frac{B}{f}=4

Hence, B varies directly with f with a constant of proportionality k=4

Factor 5w + 20 please and show your work. I need help
mars1129 [50]

The factored version of the above statement would be 5(x + 4)

In order to find this, you need to find the greatest common factor of the two coefficients. First, list the factors of each.

Factors of 5: 1, 5

Factors of 20: 1, 2, 4, 5, 10, 20

Since the highest that exists in both lists is 5, we can divide both terms by 5 and pull it out of the parenthesis like this:

5(w + 4)

Which is your final answer
