Answer:
x = 4
Step-by-step explanation:
2x-3+4x=21
Isolate the variable by dividing each side by the factors that don't contain the variable
What is the quotient of 5/8 and 20?Quotient is the term used to name the answer of the 2 or more digits being divided with each other.Now, we have 2 different numbers. A fraction and a whole number.First thing to do is to convert 5/8 to decimal number.=> 5 / 8 = 0.625Now, we have 2 numbers that needs to be divided.=> 20 as our dividend and 0.625 as our divisor=> 20 / 0.625 = 32<span>32 is the quotient when you divide 5/8 by 20</span>
Answer:
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
Together, these two angles form a flat line which is 180 degrees
(x + 7) + (4x - 52) = 180
5x - 45 = 180
+ 45 + 45
5x = 225
x = 45
Answer:
720°
Step-by-step explanation:
The "n" in the formula refers to the number of sides. The polygon shown has 6 sides, so the sum of interior angles is ...
S = 180°(6 -2) = 720°
