Try creating a proportion, take 12/21=x/15
you should have gotten x=8.571
P.S.: hope I helped
Two complementary angles sum is 90 degrees.
Angle 1 = x
Angle 2 = 2x ( two times angle 1)
Equation: x + 2x = 90
Solve:
Combine like terms:
3x = 90
Divide both sides by 3:
X = 90/3
X = 30
Angle 1= 30
Angle 2 = 60
Best choice for variables.....I would let students be " s " and parents be " p "
Answer:
log 12-2 gets u 10+3 GET U 13Step-by-step explanation:
To find this, multiply both the numerator and denominator by the same number. For example, 8 x 8 =64, and 10 x 8=80, so 64/80 would be an example of an equivalent ratio. Others could be 16/20 or 48/60. Hope this helps.
