NO LINKS NO FILES. After you add 3 to both sides of the equation 27 = m/6 - 3, what should you do next?

a_sh-v [17]

Answer:

Multiply each side by 6

Step-by-step explanation:

27 = m/6 - 3

Add 3 to each side

27+3 = m/6 - 3+3

30 = m/6

Multiply each side by 6

30*6 = m/6*6

Find the value of x and y. WILL MARK BRAINLIEST

g100num [7]

Answer:

x = 30

y = 15

Step-by-step explanation:

All the angles are 90°, so set 6y and 3x equal to 90, like so:

6y = 90

Divide both sides by 6:

y = 15

Solving for x:

3x = 90

Divide both sides by 3:

x = 30

In rectangle MNPQ with side MN = 16 in, point L is the midpoint of PQ and m∠QLM = 45°. Find the perimeter of the rectangle.

Marina86 [1]

See the attached figure

we know that
MN=16 in-------------> PQ=MN
PQ=16 in
L is the midpoint of PQ-----------> distance QL=PQ/2
QL=8 in
if m∠QLM = 45°
then
MQ=QL
MQ=8 in

Perimeter=[MN]*2+[MQ]*2=16*2+8*2=48 in

the answer is 48 in
