What is the missing side

AveGali [126]

The Pythagorean theorem applies to the sides of this right triangle.

... x² + (4/7)² = (5/7)²

... x² = 25/49 -16/49

... x = √(9/49)

... x = 3/7

The unknown side has length 3/7.

_____

You might recognize that this is a 3-4-5 right triangle with a scale factor of 1/7.

-129 = -48 - n <br> Thank you

Flauer [41]

−129=−48−n

Simplify:

−129=−48+−n

Flip the equation.

−n−48=−129

Add 48 to both sides.

−n−48+48=−129+48

−n=−81

Divide both sides by -1.

−n/−1 = −81/−1

n=81

A college some completed some courses worth 3 credits and some courses worth 4 credits. The students earned a total of 59 credit

Law Incorporation [45]

The student completed 13 courses with 3 credit hours.

Step-by-step explanation:

Total credit hours = 59 credits hours

Total courses = 18

Let,

3 credit hours courses = x

4 credit hours courses = y

According to statement;

x+y=18 Eqn 1

3x+4y=59 Eqn 2

Multiplying Eqn 1 by 3

$3(x+y=18)\\3x+3y=54\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(3x+4y)-(3x+3y)=59-54\\3x+4y-3x-3y=5\\y=5$

Putting y=5 in Eqn 1

$x+5=18\\x=18-5\\x=13$

The student completed 13 courses with 3 credit hours.
