27 over X =3 and 5y = 35 what is the value of <br> X• Y?
diamong [38]

Answer:

63

Step-by-step explanation:

\frac{27}{x} = 3

divide, 27 ÷ 3

you'll get 9, so

x = 9

Next part

5y = 35

divide both sides by 5 to isolate y,

5y ÷ 5 = 35 ÷ 5

=

y = 7

So

x = 9 and y = 7

Then let's add the numbers to our equation ( x × y)

9 × 7

=

63

Geometry Help Please!!!<br><br> See Picture Below
MArishka [77]

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.

If 2(4x + 3) -12 = 3x -6, then what value of x makes the equation true ?
poizon [28]

x=0

let's solve your equation step-by-step

2(4x+3)-12=3x-6

(8x)+(6-12)=3x-6

8x-6=3x-6

subtract 3x from both sides.

8x-6-3x=3x-6-3x

5x-6+6=-6+6

5x=0

5x/5=0/5

x=0

I hope that helps you
