Answer:
Son's age is 25.
Step-by-step explanation:
Let the Father's age be 2x.
Let the son's age be x.
Five years ago:
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then:
2x - 5/x-5 = 9/4
⇒ 4(2x - 5) = 9(x - 5)
⇒ 8x - 20 = 9x - 45
⇒ -20 + 45 = 9x - 8x
⇒ 25 = x
∴ x = 25
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50 years
Answer:
-2.5
Step-by-step explanation:
The first statement CA || DB , E is midpoint is GIVEN to you. That is the reason that statement can be made. It is GIVEN.
The second statement I would make is that ∠ACE = ∠DBE and ∠CAE = ∠EDB because Alternate interior Angles of parallel line CA || BD. You can also say ∠DEB = ∠CEA due to vertical angles being equal.
The third statement should be that AE = ED because E is the midpoint of AD.
The fourth statement is that the triangles are congruent, this is because ASA . Angle-Side-Angle are equal.
1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.
Step-by-step explanation:
Given,
Total cost for session = $43.25
Entrance fee = $7
Charges per minute = $1.25
Let,
t be the number of minutes raymond was on Trampoline
Total cost for session = entrance fee + Charges per minute * No. of minutes
1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.
