It’s 27 for sure because (7-5) is 2 times that by the power of 2 is 4 times that by 6 is 24 and 3 +24 is 27
Angle 1 and 2 are supplementary angles and need to equal 180 degrees
so angle 1 + angle 2 = 180:
6x+50 + 4x+40 = 180
combine like terms:
10x + 90 = 180
subtract 90 from each side:
10x = 90
divide both sides by 10
x = 9
Answer:
well algebra is basically about variables.
This is because you're assigning an equation or a number to a letter.
Exponents- that I don't really and inequalities
