Answer:
x=130 degree
Step-by-step explanation:
because 50+x=180
=x=130
The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"
<h3>System of equation</h3>
System of equation are made of two or more equations with unknowns
Given the system of equation
4x=5-2y
y-2x=7
From equation 2:
y = 7 + 2x
The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"

Answer:
53/99
Step-by-step explanation:
When an n-digit repeat begins at the decimal point, the repeating digits can be placed over an equal number of 9s to make a fraction. Sometimes, that fraction can be reduced to lower terms.
__
If the repeat does not start at the decimal point, the conversion can be done as follows.
For a number x with a decimal fraction that has n digits repeating, multiply by 10^n, subtract x and then divide by (10^n -1).
The fraction will be ...
(x·10^n -x)/(10^n -1) . . . where x has n repeating digits in the decimal fraction
Here, that looks like ...
Answer:
66
Step-by-step explanation:
You divide the two figures up. So there's a square and a rectangle,right? So then the perimeter is the sum of all sides so for the square all sides are equal so 5+5+5+5 since it has four sides. And for the rectangle it's 7+16+7+16. I got 16 by adding 5+11 since 11 meters is just a portion of the length of the rectangle not the whole thing. Then you add the answer you got for the square by the answer you got for the rectangle.Ur probably not gonna read this but whatever
