Answer:
<h3>
a₁₈ = 10</h3>
Step-by-step explanation:
aₙ₊₁ = aₙ + d
a₁₉ = a₁₈ + d
- 7 = a₁₈ + (-17)
a₁₈ = - 7 +17
a₁₈ = 10
Grayson: 35h + 35 = y
Ian: 45h + 15 = y
(Substituting first hour in h)
35h + 35 = y
35(1) + 35
y = 70$ in the first hour for Grayson
45h + 15 = y
45(1) + 15
y = 60$ in the first hour for Ian
Grayson charges > Ian charges
(Substituting second hour in h)
35h + 35 = h
35(2) + 35
105$ in the second hour for Grayson
45h + 15 = h
45(2) + 15
135$ in the second hour for Ian
Grayson charges < Ian charges
Answer:
In the first hour Grayson charges more than Ian.
Step-by-step explanation:
1 m = 4 cm
therefore,
A = 2.5 m = 2.5×1 m = 2.5×4 cm = 10 cm
B = 2.75 m = 2.75×1 m = 2.75×4 cm = 11 cm
D = 3.75 m = 3.75×1 m = 3.75×4 cm = 15 cm
