Answer:
In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
Variables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:
Let suppose the value of the variable x=7 changes to x=10, then the new value will be:
Therefore, the correct answer is:
In arithmetic, variables look like letters.
An outside angle equals the sum of the two opposite inside angles.
So you have:
(5x-35) = 2x +58
Solve for X then you can calculate Angle B:
(5x-35) = 2x +58
Subtract 2x from both sides:
3x -35 = 58
Add 35 to both sides:
3x = 93
Divide both sides by 3:
X = 93 /3
x = 31
Now for Angle B, replace x with 31:
Angle B = 2x = 2(31) = 62 degrees.

C = 1.5x....x = 30
C = 1.5(30)
C = 45
speedy taxis : for 30 miles
C = 1.1x + 11.5....x = 30
C = 1.1(30) + 11.5
C = 33 + 11.5
C = 44.5
city taxis : for 30 miles
C = 1.25x + 8...x = 30
C = 1.25(30) + 8
C = 37.5 + 8
C = 45.5

Answer:
Y=70
X=110
Step-by-step explanation:
if the inside of a triangle equals 180, than 70 plus 40 equals 110 which mean Y =70. if a straight line eguals 180 as well 180-70= 110 X= 110
