Answer:
x = 1
Step-by-step explanation:
To solve for a variable, you need to get the variable on one side of the equation, and by itself.
4x + 5 = x + 8
4x = x + 3 --- subtract 5 from both sides
3x = 3 --- subtract x from both sides
x = 1 --- divide both sides by 3
Answer with explanation:
The given expression is
→As, multiplication of real number follows Commutative property.
Which states that, if a and b are any two real numbers , then
a × b= b × a

Answer:
22
Step-by-step explanation:
The number of Monster High dolls is ...
12% × 25 = 3 . . . dolls
The others are not Monster High dolls. Their number is ...
25 -3 = 22 . . . not Monster High dolls
∠1 and ∠2 are alternate exterior angles where transversal BE crosses parallel lines AC and DF, therefore they are equal. ∠2 and ∠3 are opposite angles of a parallelogram, therefore they are equal.
... ∠1 = ∠2
... 3x -5 = 2x +15 . . . . substitute the given values
... x = 20 . . . . . . . . . . . add 5-2x
The measures of angles 1, 2, and 3 are 2·20+15 = 55 . . . degrees.
