<span>89+k=-42

We simplify the equation to the form, which is simple to understand
<span>89+k=-42

We move all terms containing k to the left and all other terms to the right.
<span>+1k=-42-89

We simplify left and right side of the equation.
<span>+1k=-131

We divide both sides of the equation by 1 to get k.

Evaluate the formula V = Bh3 V equals the quantity B multiplied by h end of quantity divided by 3 for B = 4 cm2 and h = 6 cm.
Marat540 [252]

Answer:

V = 8 cm³

Step-by-step explanation:

This is basically the formula for volume of pyramid:

Volume of Pyramid = 1/3 × Base Area x Height

OR

Volume of Pyramid = (Base Area x Height)/3

V = Bh/3

Given:

B = 4 cm²

h = 6 cm

V = Bh/3

  = (4 x 6) / 3

  = 24 / 3

V = 8

Hence

V = 8 cm³

If you want to represent this into inches simply divide 8 with 2.54 as

1 cm = 2.54 inches So,

8 cm / 2.54 cm  =  3.15 in

Step-by-step explanation:

4 cans and 3 loaves=11.67

8 cans and 1 loaf= 12.89.

Set up equation:

x=cans

y=loaves

4x+3y=11.67\\8x+y=12.89 This is the answer for question A.

Multiply eq1 by 2:

8x+6y=23.34

Subtract eq3 by eq2:

5y=10.45\\y=2.09

Substitute:

8x+2.09=12.89\\8x=10.8\\x=1.35

One can of soup and one loaf of bread=

1.35+2.09 or 3.44

So:

$3.44
