Jessie rode his bike for 13 hours last month. He rode 7 hours the first week of the month. He rode the same number of hours each week for the remaining 3
weeks. Which equation or inequality best represents the number of hours. h.
Jesse rode per week for the last three?

13=7+3h

Step-by-step explanation:

13 is all together, 7 for first week, and the other 3 have the same amount.

so you can say 13= 7 for the first week+ 3 of the same amount of hour which can be written as 3h.

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°
