The equivalent expression is 15x + 104 /4

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

Algebraic expressions are defined as expressions comprised of constants, variables, terms, coefficients and factors.

They are also made up of arithmetic or mathematical operations such as;

Addition
Subtraction
Division
Multiplication
Bracket, etc

Given the expression:

2(3/4x+7) - 3(1/2x-5)

solve for the bracket

3 ( 3x + 28/4) - 3 (x - 10 /2)

expand the bracket by multiplying

9x + 84 / 4 + 3x + 10/ 2

Find the lowest common multiple

9x + 84 + 6x + 20 /4

collect like terms

15x + 104 /4

Thus, the equivalent expression is 15x + 104 /4

Solving the following simultaneous equations, 4x - 5y = 17 and x - 5y = 8,

dimaraw [331]

{4x - 5y = 17

{x - 5y = 8

{x = 5y + 8

{4(5y + 8) - 5y = 17

{x = 5y + 8

{20y + 32 - 5y = 17 | - 32

{x = 5y + 8

{15y = -15 | : 15

{y = -1

{x = 5 * (-1) + 8

{x = 3

{y = -1

athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be given to the second-place finish

Agata [3.3K]

Using the permutation formula, there are 157,410 ways for the medals to be distributed.

<h3>What is the permutation formula?</h3>

The number of possible permutations of x elements from a set of n elements is given by:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this problem, 3 athletes are chosen from a set of 55, hence the number of ways is given by:

P(55,3) = 55!/52! = 157,410

157,410 ways for the medals to be distributed.
