It will equal 22.5 since you need to multiple
Step-by-step explanation:
first you have to use the formula for circle is 2πr
22
π= ----
7
and r stands for radius
Answer: x = 21°
Step-by-step explanation:
37 + 4x + (3x - 4) = 180° Original Equation
37 + 4x + 3x - 4 = 180° Commutative Property of Addition
7x + 33 = 180° Combine like terms
7x = 148° Subtract 33 from both sides
x = 21° Divide both sides by 7
Yes because 0 and 4 dont equal 10 and 20 and 40 dont equal 100. So no and 40 + 23 = 63.
Answer:
(0,6)
Step-by-step explanation:
The given system of equations is
and
We substitute the first equation into the second equation to get:
We expand to get:
We group similar terms to get:
Put x=0 in to the first equation to get:
Therefore the solution is (0,6)
