Answer & Step-by-step explanation:
Vertical angles are congruent meaning that these two angles are going to have the same measurement. Since we know this, then we can set up an equation where one angle is equal to the other.
x + 10 = 55
Subtract 10 on both sides of the equation.
x = 45
So, the value of x is 45.
Answer:
SQUARE 1:
100% ; 75%
Step-by-step explanation:
SQUARE 1:
If each square represents a whole ; the percentage of a whole = 100%
Dividing the square into 4 equal parts :
Percentage of each part :
100% ÷ 4 = 25%
Percentage represented by the shaded part:
(Percentage of each shaded part * number of shaded part)
(25% * 4) = 100%
SQUARE 2:
each square represents a whole ; the percentage of a whole = 100%
Dividing the square into 4 equal parts :
Percentage of each part :
100% ÷ 4 = 25%
Percentage represented by the shaded part:
(Percentage of each shaded part * number of shaded part)
(25% * 3) = 75%

Answer:
40 rows will hamsters fill
Step-by-step explanation:
As per the statement:
There are 486 hamsters at a private showing of a new documentary about humans.

then;
They will fill = 
Therefore, the best estimate the rows will hamsters fill is 40 rows.
Answer:
x = 45
Step-by-step explanation:
Re-order terms so constants are on the left
15 * x/9 - 42 =28
Combine multiplied terms into a single fraction
15x/9 - 42 = 28
Cancel terms that are in both the numerator and denominator
5x/3 - 42 = 28
