Answer:
C
Step-by-step explanation:
5+2y+3z=5+3z+2yA
Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.
5+3z+2yA=5+2y+3z
Resta 5 en los dos lados.
3z+2yA=5+2y+3z−5
Resta 5 de 5 para obtener 0.
3z+2yA=2y+3z
Resta 3z en los dos lados.
2yA=2y+3z−3z
Combina 3z y −3z para obtener 0.
2yA=2y
Anula 2 en ambos lados.
yA=y
Divide los dos lados por y.
y
yA
=
y
y
Al dividir por y, se deshace la multiplicación por y.
A=
y
y
Divide y por y.
A=1
So the scale used was
1 inch = 6 feet
Step-by-step explanation:
Given
Length of library on drawing = 13 inches
Actual length of library = 78 feet

So,
Scale = 
So the scale used was
1 inch = 6 feet

Step-by-step explanation:
Supplementary angles add up to 180 degrees
Let x represent the smaller angle:
x + (x + 81.2) = 180
2x + 81.2 = 180
2x = 98.8
x = 49.4 degrees
therefore:
smaller angle = 49.4 degrees
larger angle = 49.4 + 81.2
= 130.86 degrees
Answer:
B. 
Step-by-step explanation:
Total paper in the hat:
2 blue + 6 red + 10 yellow + 7 purple = 25 total pieces of paper
P(AB) = 7 / 25 x 2 / 25
A is the probability of pulling a purple paper
B is the probability of pulling a blue paper
