olchik [2.2K]

Answer:

Step-by-step explanation:

To find the adult weight, multiply 12 by 5.

Since 12 pounds is 20% of the adult weight, 100% of the adult weight would be 12 times 5.

12(5)

6x+12y+5+2y+8 what’s the coefficient of y and what’s the constant
Rudik [331]

The coefficient of y is 14 and the constant is 13.

You can find this by combining like terms first.

6x + 12y + 5 + 2y + 8

6x + 14y + 5 + 8

6x + 14y + 13

Now the coefficient is the number next to y. The constant is the number on its own.

-Dominant- [34]

Answer:

The actual dimensions of the kitchen are 12\ ft by 14\ ft

Step-by-step explanation:

step 1

Find the scale  of the drawing

To find the scale , remember that is equal to the ratio of  the corresponding dimension in the drawing divided by the corresponding actual dimension

so

\frac{0.8}{4}\frac{in}{ft}=0.2\frac{in}{ft}

step 2

To find the actual dimensions of the kitchen, divide the dimension in the drawing by the scale

so

2.4\ in=2.4/0.2=12\ ft

2.8\ in=2.8/0.2=14\ ft
