Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added toge

Karolina [17]

The first equation must be multiplied by 18 and second equation must be multiplied by 8

Solution:

Given system of equations are:

$\frac{1}{4}x -\frac{1}{6}y = 5$ --------- eqn 1

$\frac{4}{5}x +\frac{3}{8}y = 10$ -------------- eqn 2

Multiply the second equation by 8 both sides to remove the fraction in the variable y

$8(\frac{4}{5}x +\frac{3}{8}y = 10)\\\\\frac{32x}{5} + 3y = 80 -------- eqn 3$

Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y

$18(\frac{1}{4}x -\frac{1}{6}y = 5)\\\\\frac{18}{4}x -3y = 90 ---------- eqn 4$

Add eqn 3 and eqn 4

$\frac{32}{5}x +3y +\frac{18}{4}x -3y = 80+90\\\\\frac{32}{5}x+\frac{18}{4}x = 170$

Thus the y-term is eliminated

Therefore, first equation must be multiplied by 18 and second equation must be multiplied by 8

Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on

devlian [24]

Answer:

The total minutes he spend on his homework are 50 minutes.

Step-by-step explanation:

It is given that Jordan spent 22% of his time for homework on maths.

It is also given that he spent 11 minutes of time on maths homework.

The above two statements are equal.

Let the total time for homework be "x".

Thus, the equation can be written as,

$(\frac{22}{100})(x) = 11$

$x = (\frac{100}{22})(11) = 50 minutes$

Thus the total minutes he spend on his homework are 50 minutes.
