Answer:
A) T and R
B) <SQR or <RQS
C) Q
Step-by-step explanation:
A) The sides of a angle are the end points which are T and R in this case.
B) Angle 2 has S and R and its end points. And the vertex which is Q is always in the middle, so the angle is <SQR and <RQS
Answer:
Fred is 28 yrs old. Nathalie is 12yrs old
Step-by-step explanation:
Let Nathalie's age be x
Let Fred's age be a
x+a=40 yrs•••••1
4x+a=76yrs•••••2
a=40-x
Substitute a for 40-x in equation (2)
4x+40-x=76
3x=76-40
3x=36
x=12
a=40-12
a=28
Let the original number be x
X^2 + 11 = 36
Subtract 11
X^2 = 25
Square root both
X = 5
Solution: her original number is 5
Which variable are we solving for?
For y:
y= 5x-4/ 13
For x:
x= 13y+4/ 5
... there is no math problem here
