Answer:
Y=15
Step-by-step explanation:
Rewrite the equation with the given Variable substitution if you
Y = 4(3) + 3
Solve using PEMDAS
4 x 3 = 12
Rewrite
12 + 3 = y
Y=15
3a, because both terms contain a, and 6 is divisible by 3
You divide 2 by 9 which is .2222--- or .2 if you round it to the nearest tenths.
Whenever you want to change a fraction to a decimal, you divide the numerator by the denominator.
C=5/9 (95F-32)
C=5/9 (63)
C= 5/9 times 63/1= 35
Celsius= 35 degrees
There is the answer :) hope that helps more than the first person who answered lol
We can use a system of equations to solve this.
Length 1 = x
Length 2 = y
Set up the system.
2x+2y=38
x+1=4y
Isolate the variable on one equation.
x=4y-1
Substitute that into the other equation.
2(4y-1)+2y=38
Solve.
8y-2+2y=38
10y=40
y=4
Substitute back into other equation.
x=4(4)-1=16-1=15
The lengths are 15 cm and 4 cm.
Hope this helps!
