A number (we don’t know the number so I’ll use X) plus five. So we can start the equation of with X+5 then divided by 3=7 so X+5➗3=7 so to solve what X is we can just go in reverse. 7 TIMES 3= 21-5=16 so X=16

Answer:

The required equation is \frac{x+5}{3}=7

The value of x is 16.

Step-by-step explanation:

Consider the provided information.

if a number is increased by 5 and the result is then divided by three,the result is seven.

Let the number is represented by x.

Increase the number by 5: x+5

Now divide the result by 3, and result is seven.

This can be written as:

\frac{x+5}{3}=7

Now solve the equation for x as shown.

\frac{x+5}{3}=7

x+5=21

Subtract 5 from both sides.

x=16

Hence the value of x is 16.

The legs of a right triangle are 10 centimeters and 24 centimeters long. What is the length of the hypotenuse?
Rina8888 [55]
A² + b² = c²

Where a and b are the legs and c is the hypotenuse

So, plug in 10 for one of the legs and 24 for the other leg

c will be left blank because that is what you are trying to find, the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

Take the square root of both sides of the equation to isolate c

√676 = √c²

Square of c and the square root cross out on the right

Take the square root of 676

c = 26

So, the length of the hypotenuse is 26 centimeters
