Aclass has $90 to spend on a field trip. the field trip costs $2.50 per person and there will be 5 chaperones on the trip. one
student used the inequality 90 > 2.50(x+5) to find x, the number of students that the field trip budget could accommodate.
which best describes the error in the student's inequality?
the expression representing the cost should be 2.50(5x).
the expression representing the cost should be 2.50(x+5x).
the inequality symbol should be instead of > since up to and including 590 may be spent.
the inequality symbol should be s instead of > since less than or equal to $90 may be spent.

answer:

step-by-step explanation:

you should consider the current mileage when purchasing a used car. of course, the fewer miles it has been driven, the better. an average of 12,000 miles per year is considered the norm. of course, some cars are driven less than that, but many are driven much more due to long commuting distance.

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°
