Step-by-step explanation:
PEMDAS states that you do things in the parenthesis first.
Answer:
A. :)
Step-by-step explanation:
Answer:
x=5 1/4
Step-by-step explanation:
2 1/4= 
---> divided by 3 to find 1/7x----> 
=1/7x---> x=21/4---> x=5 1/4
-7x + 2x (add common factors)
-5x+6+21 (what happen to one side happens to the others
-5x=21 (divide by five)
x= -3
Answer:
70° , 70°
Step-by-step explanation:
The 2 angles are corresponding and are congruent, then
23x + 1 = 4 + 22x ( subtract 22x from both sides )
x + 1 = 4 ( subtract 1 from both sides )
x = 3
Then the angles are
23x + 1 = 23(3) + 1 = 69 + 1 = 70°
4 + 22x = 4 + 22(3) = 4 + 66 = 70°
