Substitute: 7.5x = 5.5x + 10
Umnica [9.8K]

The value of x is 5

<h3>What are algebraic expressions?</h3>

Algebraic expressions are expressions made up;

  • Factors
  • variables
  • terms
  • constants

They also consist of mathematical operations such as addition, multiplication, division, subtraction, parenthesis, brackets, etc

We have the expression as;

7.5x = 5.5x + 10

collect like terms

7.5x - 5.5x = 10

subtract the like terms

2.0x = 10

Make 'x' the subject

x = 10/2. 0

x = 5

Thus, the value of x is 5

Find the length of the hypotenuse in the right triangle below. 39in, 52in
Bingel [31]
If two sides of a right triangle are x and y, the hypotenuse, h is:

h^2=x^2+y^2, in this case x and y are 39 and 52 respectively so:

h^2=39^2+52^2

h^2=1521+2704

h^2=4225

h=√4225

h=65 in

So the hypotenuse is 65 inches.

A bicycle wheel has a radius of 13 inches.
mario62 [17]

Step-by-step explanation:

the circumference of a wheel is one revolution

so

formula: circumference=π*diameter

D=26cm (13*2 to find the whole length from one end to other)

so you'll do 3.14*26 equals 81.64

one revolution=81.64

30 revolutions=2,448.3 inches (times by 30 with 81.64)
