**Step-by-step explanation:**

Answer:

The coefficient in the equation 12y-7 is 12.

Step-by-step explanation:

Answer:

19 cm³

Step-by-step explanation:

The figure cam be decomposed into two cuboid.

✔️Dimension of cuboid 1:

L = 2 cm

W = 1 cm

H = 8 - 3 = 5 cm

Volume = L * W * H

Volume = 2*1*5 = 10 cm³

✔️Dimension of cuboid 2:

L = 3 cm

W = 1 cm

H = 3 cm

Volume = L*W*H = 3*1*3

Volume = 9 cm³

✅Volume of the irregular figure = 10 + 9 = 19 cm³

A. 2 + (1/2)* 1 = 2.5

B. 2 + (1/2)*2 = 3

C. 2 + (1/2)*3 = 3.5

D. s = 2 + (1/2)*m

2. 8 = 2 + (1/2)*m

6 = (1/2)m

m = 12

It is asking what 7/8 of 2/3 is. The "of" means you need to multiply. 7/13 is the answer.
