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 determine the measure of each angle?

Two complementary angles have measures of s and t. if t is less than twice. The system of a linear equation that can be used to determine the measure of each angle is called substitution.

A system of linear equations is the arrangement of one or more similar equations involving the same variables.

From the given information;

Now;

We know that a complementary angle is an angle that the addition of the angles is equal to 90°

s + t = 90

Therefore, we can conclude that the system of a linear equation that can be used to determine the measure of each angle is called substitution.

angle 1 (s):

angle 2 (t): t < 2s  

s + t = 90

t < 2s

You didn't provide the choices so hopefully you can figure it out with the information I provided.

Note: "t" must be less than 30

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
