Answer:
There are 10 decimeters in one meter so the answer is 15.5 / 10 = 1.55 meters.
x = 3 + y Eqn(1)
y = -2x + 9 Eqn(2)
Let us solve the system of equations with the substitution method
x - 3 = y (Subtracting 3 from both sides of the Eqn(1))
Replacing y = x - 3 in Eqn (2), we have:
x - 3 = -2x + 9
x = -2x + 9 + 3 (Adding 3 to both sides of the equation)
x + 2x = 9 + 3 (Adding 2x to both sides of the equation)
3x = 12 ( Adding like terms)
x = 12/3 (Dividing by 3 on both sides of the equation)
x = 4
Replacing x=4 in Eqn(1), we have:
4 = 3 + y
4 - 3 = y (Subtracting 3 from both sides of the equation)
y=1
The answers are:
x= 4 and y=1
3y+6 is the answer
-9+5(y+3)-2y
-9+5y+15-2y
-9+3y+15
=3y+6

Given : Expression 
To find : Select the expression that is equivalent to expression ?
Solution :
Re-write the expression as,
The above are the possible equivalent expressions.
Answer:
3.
Step-by-step explanation:
Since it states it needs to be cut into pieces, it's division, so since it's division we do KCF - keep change flip
We keep the first term, then we change the sign to a multiplication sign and flip the numerator and the denominator for the second term, so your equation would be :
6/8 × 4/1
6 times 4 would be 24, then we put 24 over 8, 24/8, - then you just divide 24 by 8 which would be 3. I hope this helps.
