Let’s arrange the fist equation
x+y=12
2x+3y=29
Multiply equation 1 by 2
So it will be
2x+2y=24
Subtract eq 1 from eq 2
2x+3y=29
2x+2y=24
—————-
Y =5
Put value of y in eq 1
2x+2y=24
2x +10= 24
2x= 24-10
2x= 14
x=14/2
x=7
S.S= (7,5)
Answer:
8 minutes
Step-by-step explanation:
The amount in the glass after m minutes can be described by ...
a = 4 + 3/2m
We want to find m when a=16, so ...
16 = 4 + 3/2m
12 = 3/2m . . . . . subtract 4
8 = m . . . . . . . . . multiply by 2/3
It will take 8 minutes to fill the glass.
Answer:
y=5x+4
Step-by-step explanation:
y=mx+b
m=slope
x=constant
b=y intercept
The answers are B and C because anything in parentheses has to do with vertical change, while outside of the parentheses is horizontal
Answer:
n = 59
Step-by-step explanation:
The given equation of n is 
and we have to solve it for n.
........... (1)
⇒ 
{Rationalizing the numerator}
⇒ 
.............. (2)
Now, adding (1) and (2) we get
⇒ n + 5 = 64 {Squaring both sides}
⇒ n = 59 (Answer)
