If you would like to express h in terms B and V, you can do this using the following steps:

V = 1/3 * B * h     /*3
V * 3 = B * h       /B
V * 3 / B = h
h = V * 3 / B

The correct result would be h = V * 3 / B.

Answer: h=\dfrac{3V}{B}

Step-by-step explanation:

Given: The formula for the volume of a pyramid is

V=\dfrac{1}{3}Bh

To express h in terms of B and V , first we need to multiply 3 on both sides of the above equation , we get

Bh=3V

Now for the second step , divide B on both sides, we get

h=\dfrac{3V}{B}

Hence, The expression for h in terms of B and V = \dfrac{3V}{B}

One fifth of a number, decreased by 17 is 41 in algebraic expression
asambeis [7]

The correct algebraic expression is X ÷ 5 - 17 = 41

<h3>What is an algebraic expression?</h3>

An algebraic expression is a term that refers to a way of representing mathematical operations in which letters and numbers are combined, related to signs of the operations such as:

  • Addition (+)
  • Subtraction (-)
  • Multiplication (×)
  • Division (÷)
  • Empowerment (x^{2})

According to the above, we can infer that the correct algebraic expression would be:

  • X ÷ 5 - 17 = 41

In this algebraic expression the letter X represents a number that we do not know and we must find.

Solve the following for the specified variable<br><br> Z=s/2(P+p); for P
lapo4ka [179]

Answer:

\boxed{\sf P = \frac{2Z}{s} - p}

Step-by-step explanation:

\sf Solve \ for \ P: \\ \sf \implies  Z = \frac{s}{2} (P + p) \\ \\ \sf Z = \frac{s}{2} (P + p) \ is \ equivalent \ to \ \frac{s}{2} (P + p) = Z: \\ \sf \implies \frac{s}{2} (P + p) = Z \\ \\  \sf Divide \ both \ sides \ by \ \frac{s}{2} : \\ \sf \implies P + p = \frac{2Z}{s} \\ \\ \sf Substrate \ p \ from \ both \ sides: \\ \sf \implies P = \frac{2Z}{s} - p

Please help ASAP thanks

Answer:

x = 2.5 inches. Or

x = 5/2

Step-by-step explanation:

Length: 7 + 2x

Width: 5 + 2x

Note that you have to add x at each end of the picture and onto each part of the width.

The entire area is 120 square inches.

Formula

L*W = Area

(2x + 7)(2x + 5) = 120

Solution

4x^2 + 10x + 14x + 35 = 120                Subtract 120 from both sides. Add xs

4x^2 + 24x + 35 - 120 = 0

4x^2 + 24x - 85 = 0                             Factor

(2x + 17)(2x - 5)

2x + 17 has no meaning. It will give -  8.5 which is not possible.

2x - 5 =0

2x = 5                                                  Divide by 2

x = 5/2

x = 2.5

Note: I don't know which one the computer is looking for.

When simplifying an expression using order of operations addition MUST
Rama09 [41]

Answer:

The answer is False,

Step-by-step explanation:

The answer is False because in some expressions if there are parentheses and there is a subtraction problem in the parentheses but there is an addition problem in front of the parentheses that does not exactly mean that you do the addition first, this is because the subtraction is inside the parentheses and so since the subtraction is in parentheses it is done fist.
