Answer:

y=3 x=-2

Step-by-step explanation:

-3(2y-8)+2y=12

-6y+24+2y=12

-4y+24=12

-4y=-12

y=3

x=2(3)-8

6-8

x=-2

-3x + 2y = 12
-3 (2y - 8) + 2y = 12
-6y + 24 + 2y = 12
-4y + 24 = 12
-4y = -12
y = 3

x = 2y - 8
x = 2(3) -8
x = 6-8
x = -2

Therefore, the coordinates are (-2, 3).

CINDY made costume decorations. She used 1/10 of a meter of ribbon for each decoration which she got by cutting 3/10 of a meter

Brilliant_brown [7]

Answer:

Cindy made 3 decorations with the ribbons

Step-by-step explanation:

Since Cindy used 1/10 of a metre of ribbon to make just one decoration that she obtained by dividing 3/10 of a meter of ribbon into equal parts, then we can calculate the number of decorations that Cindy made. In this scenario, all we need is an idea on how to divide fractions and we are good to go.

If Cindy used 1/10 of a metre obtained by dividing 3/10 of a metre of ribbon to make decorations, then the number of decorations she made can be gotten by dividing 3/10 by 1/10

i.e 3/10 ÷ 1/10

= 3/10 × 10/1

= 3 decorations.

That is she used 1/10 + 1/10 + 1/10 = 3/10 to make (3 decorations).
