Be:
Number of hours: n
<span>The cost of renting a bike for the first hour is $7:
n=1→f(n)=f(1)=$7
</span>He is charged $2.50 for every additional hour of renting the bike:
f(n)=f(n-1)+2.50, for <span>n ≥ 2
</span>
f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2 (sixth option)
</span>
f(n)=f(1)+2.50(n-1)
f(n)=7+2.50(n-1)
f(n)=7+2.50n-2.50
f(n)=2.50n+4.50 (fifth option)
Answers:
Fifth option: f(n)=2.50n+4.50, and
Sixth option: f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2</span>
(y + z2) * x
(5 + 3(2)) * 2
(5 + 6) * 2
11 * 2
Your answer is 22
Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:
Solving for x:
Finally we obtain that 87.5mL of water should be used for 250g of plaster.
so it would be 8x13/8+13, which would simplify out to be 104/8+13 which would then simplify out even more to be 104/21 as a fraction or 4.95 as a decimal
hope this helps!! :) ❤❤❤❤
Answer:
Step-by-step explanation:
1). 7x - 2y = 5 , A = 7 , B = 2 , C = 5
2). 4x - y = 1 , A = 4 , B = - 1 , C = 1
3). 5x - 2y = 3 , A = 5 , B = - 2 , C = 3
4). 4x - 3y = 3 , A = 4 , B = - 3 , C = 3
5). 2x + y = 15 , A = 2 , B = 1 , C = 15
