System of equation consists of two or more equations with unknow variables. A possible step used in eliminating the y-term is (y + z  6) *5

<h3>System of equations</h3>

System of equation consists of two or more equatons with unknow variables.


Given the system of equations

y + z = 6

5y + 9z =1

In order to eliminate the variable "y", we <em>will multiply equation 1 by 5 and subtract from equation 2;</em>

5y + 5z = 30

5y + 9z = 1

Subtract

5z - 9z = 30 - 1

-4z =29

This leaves only the variable "z" eliminating variable. "y"

avanturin [10]

Answer:

6 cm

Step-by-step explanation:

wire was bent into the shape of a rectangle with width 5 and length 7. If this wire is bent into shape of a square, what is the length of a side of the square

Given that:

Rectangular wire with the following dimension :

Width = 5

Length = 7

To obtain the total length of the wire :

Perimeter of rectangle :

2 (length + Width)

2 (5 + 7)

2(12)

= 24 cm

The length of each side of the square will be :

Number of sides = 4

Length of each side :

24 / 4 = 6 cm

Which statements help explain this result? Check all that apply.
12345 [234]

Answer:

The bottle was 1/2 full at 11:35 a.m. and doubled again after 5 minutes.

The bottle was 1/4 full at 11:30 a.m. and doubled twice after 10 minutes.

Exponential growth involves a constant multiplicative rate of change.

Step-by-step explanation:

All that apply in the statements are as follows:

(a) The bottle was ½ full at 11:35 a.m. and doubled again after five minutes, which indicates that the bottle doubled at 11:40 am

(b) The bottle was ¼ full at 11:30 a.m. and doubled twice after 10 minutes. These means that the bottle was ½ full at 11:35 a.m. (i.e. five minutes ago the bottle was at ¼ full at 11:30 am, after five minutes, the which is was ½ full at 11:35 am but later became full at 11:40 am)

(c) Exponential growth involves a constant multiplicative rate of change (1.e. the rates of growth is twice every five minutes)
