Ms. Miller bought burgers for her math students. She paid $39.78 for all burgers. She has 17 students in her class. Choose a variable to represent the cost of one burger, and write an expression for this. I will give brainliest to the best answer, please answer quickly.

The variable that will represent the cost of one burger will be "b".

The equation is $39.78/17=b

Answer is $2.34

Step-by-step explanation:

Find out how many students she has.

Find out how much she paid for all burgers.

Divide amount she paid for all the burgers by the amount of students she has.

Finally, you have your answer.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
