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.
Answer:
10

Answer:
<u>∠ABC = 39°</u>
Step-by-step explanation:
Since ED bisects ∠CBD :
<u>∠EBD = ∠CBE = 30°</u>
<u />
Now, <u>∠ABD = ∠ABC + ∠CBE + ∠EBD = 99°</u>
Solving :
- 99° = ∠ABC + 30° + 30°
- ∠ABC = 99° - 60°
- <u>∠ABC = 39°</u>
So five plus three times x equals twenty because five is alone and you’re adding three times x and is represents the equal sign and twenty is alone. So the equation is this 5 + 3x = 20
X= 130°
Step-by-step explanation:
From E, draw EF || AB || CD.
Now, EF || CD and CE is the transversal.
So; <DCE + <CEF = 180° [co. int. <s]
x° + <CEF = 180°
<CEF = (180° – x°).
Again, EF || AB and AE is the transversal.
So; <BAE + <AEF = 180° 01 [co. int. <s ]
105° + <AEC+ <CEF = 180°
105° +25° + (180° – x°) = 180°
x° = 130°
