Answer:
it's D
Step-by-step explanation:
y= .05x+20
x=50
y=.05(50)+20
2.5+20
y=22.5
y=.25x+10
x=50
y=.25(50)+10
12.5+10
y=22.5
Answer:
33
Step-by-step explanation:
GCF stands for "greatest common factor". This means what is the largest quantity you can divide into 6x and 20xyz without a remainder. First see what is the biggest number you can divide 6 by and also 20 without having a remainder. Next, you should see which variables 6x and 20xyz have in common. variables are the (x,y, and z). Put these two values togther and this will be your GCF.
∠1 ≅∠3 = 130º
1) Gathering the data, accordingly to what's been told we can write:
∠1 + ∠50º = 180º <em>Definition of two supplementary angles</em>
∠50 +∠3 = 180º
2) Then we can evaluate:
∠1 + ∠50º = 180º <em>Subtract ∠50º from both sides</em>
∠1 = 180º -50º
∠1 = 130º
∠50 +∠3 = 180º
∠3 = 180º-50º
∠3 = 130º
3) Hence ∠1 ≅∠3 = 130º because the definition of supplementary angles is the same.
