Two complementary angles have measures of s and t. if t is less than twice s, which system of linear equations can be used to de

stealth61 [152]

The required expressions are both equations 1 and 2 as shown:

$s + t = 90 ......... 1$

$t$ .... 2

Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.

According to the question, if two complementary angles have measures of s and t then:

$s + t = 90 ......... 1$

Twice of 's' is expressed as $2s$

If t is less than twice s, this can be expressed as $t$ .... 2

The required expressions are both equations 1 and 2 as shown:

$s + t = 90 ......... 1$

$t$ .... 2

V=lwh solve for l in literal equations

Delicious77 [7]

Basically, you just perform whatever operations are needed to get the variable you DON'T know by itself on one side of the equal sign, plug in the variables you do know, and you have it. In your example, say you don't know the length, but you know the others:
V = l*w*h
V/w*h = l*w*h/w*h
V/wh = l
Now l is by itself, so you can substitute values for the other variables and solve for l.
