3 1/2 - 1 1/3 x x= 1
slamgirl [31]

Answer:

The value of x for the given expression is \frac{15}{8}

Step-by-step explanation:

Given as :

<u>The expression is written </u>

3\dfrac{1}{2} - 1\dfrac{1}{3} × x = 1

Or, 1\dfrac{1}{3} × x = 3\dfrac{1}{2} - 1

Or, \frac{(1\times 3) + 1}{3} × x = \frac{(3\times 2) + 1}{2} - 1

Or, \dfrac{4}{3} × x = \dfrac{7}{2} - 1

Or,  \dfrac{4}{3} × x = \dfrac{7-2}{2}

Or, \dfrac{4}{3} × x = \dfrac{5}{2}

∴ x = \frac{\frac{5}{2}}{\frac{4}{3}}

Or, x = \frac{5\times 3}{2\times 4}

I.e x = \frac{15}{8}

So, The value of x = \frac{15}{8}

Hence The value of x for the given expression is \frac{15}{8} Answer

Step-by-step explanation:

The tree and its shadow from a right triangle with the tree being the perpendicular and the shadow being the base as shown in the figure attached.

Therefore the angle θ formed by the sun's rays and the ground is:

\theta = tan^-1(\frac{18}{15} )=\boxed{50.2^o}

Which number is irrational? A. 3/8 B. 56/8 to the fourth C. 36 to the fourth over 4 to the fourth D. 0.19 repeating
mixer [17]
I believe that none would be irrational; an irrational number can't have terminating or repeating decimals. 3/8= .375, (56/8)^4=7^4=2,401, 36^4/4^4=6561, and .19 repeating is a repeating decimal.
