1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2)<br> what is v?

Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

$1 \frac{1}{2} \\ = \frac{2 \times 1 + 1}{2} \\ = \frac{3}{2}$

In order to find the value of v, you have to substract 3/4 to both sides :

$\frac{3}{2} = v + \frac{3}{4}$

$\frac{3}{2} - \frac{3}{4} = v + \frac{3}{4} - \frac{3}{4}$

$v = \frac{3 \times 2}{2 \times 2} - \frac{3}{4}$

$v = \frac{6}{4} - \frac{3}{4}$

$v = \frac{3}{4}$

Three-fourths was subtracted from a number, and then 5/4 was added to the result. The sum was -7.

Rasek [7]

Hi there!

Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :

(x - $\frac{3}{4}$ ) + $\frac{5}{4}$ = -7

subtract $\frac{5}{4}$ on each side of the equation

x - $\frac{3}{4}$ = -8.25

add $\frac{3}{4}$ on each side of the equation

x = -7.5

-7.5 - 3/4 = -8.25

-8.25 + 5/4 = <u>-7</u>

So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.

There you go! I really hope this helped, if there's anything just let me know! :)
