M+1 3/8=5 What does m equal?
Arte-miy333 [17]

\text{ The value of m is equal to 3.625 or }\frac{29}{8} \text{ or } 3\frac{5}{8}

<em><u>Solution:</u></em>

Given that we have to find the value of "m"

Given expression is:

m + 1\frac{3}{8} = 5

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>

Steps to follow:

Divide the numerator by the denominator.

Write down the whole number answer.

Then write down any remainder above the denominator.

Therefore,

1\frac{3}{8}=\frac{8 \times 1+3}{8} = \frac{8+3}{8} = \frac{11}{8}

Now the expression becomes,

m + \frac{11}{8} = 5

Keep the variable "m" on L.H.S and move the constant to R.H.S

m = 5 - \frac{11}{8}\\\\m = \frac{5 \times 8 -11}{8}\\\\m = \frac{40-11}{8}\\\\m = \frac{29}{8}\\\\\text{In mixed fractions, we can write as }\\\\m = \frac{29}{8} = 3\frac{5}{8}

Thus value of m is equal to 3.625 or \frac{29}{8} \text{ or } 3\frac{5}{8}

Which of the following expressions is equivalent to (8x)^2/3 ?
miv72 [106K]

Answer:

<h3>4x^2/3</h3>

Step-by-step explanation:

Given the expression (8x)^2/3

This can also be expressed as;

(8x)^2/3

= (2^3x)^2/3

= (2³)^2/3 * x^2/3

= 2^2 * x^2/3

= 4x^2/3

Hence the equivalent expression is 4x^2/3

In ΔRST, the measure of ∠T=90°, TS = 65, SR = 97, and RT = 72. What ratio represents the cotangent of ∠S?
horrorfan [7]

Answer:

65/72

Step-by-step explanation:

Given that ∠T=90° then the triangle ΔRST is  a right angled triangle. Considering ∠S, RT is the opposite side, TS is the adjacent side and RS is the hypotenuse side. Using the notation

SOH CAH TOA

Tan ∠S = 72/65

Hence the cotangent of ∠S which is the inverse of the tangent will be

= 65/72
