Answer:

33 feet

Step-by-step explanation:

Given

1 inch= 12 feet

we have to find actual length of wall when length of wall on drawing is 2 3/4 inches

to do that lets multiply LHS and RHS of above equation with  2 3/4

2 3/4 inches = (2*4 +3 )/4 = 11/4 inches

1 inch* 2 3/4= 12 feet* 2 3/4

1*11/4 inches = 12*11/4 feet = 33 feet

Thus, actual length of wall is 33 feet.

A number increased by 4 is the same as 19 minus 2 times the number
ElenaW [278]

Hello from MrBillDoesMath!

Answer:

n = 5


Discussion:

Let the original number be "n"  Translating the problem  statement to mathematical symbolism:

n + 4 = 19 - 2n                   =>  add 2n to both sides

n + 2n + 4 = 19 - 2n + 2n  =>  combine like terms

3n + 4 = 19                        => subtract 4 from both sides

3n = 19 -4  = 15                 => divide both sides by 3

n = 15/3 =5


Check: Does 5 +4 = 19 - 2(5)? Does 9 = 9? Yes. so the value for n is confirmed correct.


Thank you,

MrB

14 V = bdt. Solve the formula for de
snow_tiger [21]

Answer:

d=\dfrac{V}{bt}

Step-by-step explanation:

It is given that,

V = bdt i.e. V is equal to the product of b, d and t

We need to find the formula for d.

Dividing both sides of the given expression by bt

So,

\dfrac{V}{bt}=\dfrac{bdt}{bt}\\\\d=\dfrac{V}{bt},\ \text{bt in both denominator and numerator cancel out}

Hence, d=\dfrac{V}{bt} is the value of d.
