Answer:
2. RS = ST, Reason: Midpoint of a line (definition)
4. RS = XY, Reason: Transitive Property of congruence (if a=b, and b=c, a=c)
Step-by-step explanation:
A Midpoint divides a line exactly in half, due to the definition of a Midpoint. So, RS = ST, since they measure the same distance from the Midpoint. RS=XY because of the Transitive Property of Congruence. If ST = XY, and RS = ST, then RS = XY.
There is no question therefore I cannot answer
Answer:
15
Step-by-step explanation:
Coefficient means the number in front of the variable (like r) or term (a letter).
In your expression 3-15r, 15 is the coefficient.
I hope this helps.
The answer to your question would be shown in steps. The decimal form is -1.2. You need to do a formula called "Keep, Change, Switch," which -3/4 is kept, division is turned into multiplication, and 5/8 is switched to make 8/5. Now we do the math, so we multiply -3 by 8 and 4 by 5, giving us from a fraction, -24/20, but you can simplify that, giving us the fraction, -1' 1/5 (I put ' as in that any number to the left of ' is a whole number, not a fraction for a numerator or denominator.

Answer:
C
Step-by-step explanation:
First we simplify what we can in the expressions. 3sqrt(3y) can't be so we leave that. We want to try and get everythig to have sqrt(3y) in it though.
sqrt(27y^5) = sqrt((3^3)y^2y^3) = sqrt(3^2y^4*3y) = 3y^2*sqrt(3y)
y^2*sqrt(75y) = y^2*sqrt(5^2*3y) = 5y^2*sqrt(3y)
So now we have 3sqrt(3y) - 3y^2*sqrt(3y) + 5y^2*sqrt(3y)
If we factor out sqrt(3y) we get (3-3y^2+5y^2)sqrt(3y) = (3+2y^2)sqrt(3y) So that's C
Let me know if you don't get how I did something though and I'll be happy to explain it.
