4 minutes

Set up 2 equations and solve

let b represent time taken to ride around block and

let n represent time taken to ride around neighbourhood, then

10b + n = 24 → (1)

5b + 2n = 18 → (2)

multiply (1) by - 2

- 20b - 2n = - 48 → (3)

add (2) and (3) term by term to eliminate n

- 15b = - 30 ( divide both sides by - 15 )

b = 2

substitute b = 2 into (1) and solve for n

20 + n = 24 ( subtract 20 from both sides )

n = 4

Thus it takes 4 minutes to ride around the neighbourhood

If 12000 people voted in the election,how many people were from 50 to 64 years old
inessss [21]
Assuming that this question is based on a graph, and that this graph tells us that people 50-64 years make up 35% of all the voters, then it would mean that
35%of 12000=\frac{35}{100} *12000=35*120=4200

So, assuming that people at age 50-64 make up 35% of the voters, then 4200 of them voted.

Find the indicated term of the given arithmetic sequence. a1=45, d= -3, n=10
klasskru [66]

In this sequence, we're given the first term, which is 45.

The difference between each term is -3, which means 3 will be subtracted in each term.

We're asked to find the value of the tenth term, and we can do so by using this formula:

a(n) = a(1) + d(n - 1)

Replace values.

a(10) = 45 + -3(9)

a(10) = 18

<h3>The value of the tenth term is 18.</h3>

Please help me and if I can I’ll help you but please I don’t get it!!
kobusy [5.1K]

Step-by-step explanation:

To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).

\frac{65}{1} =\frac{13}{x}

We use this equation to find x. To solve, we divide 13 by 65 to get our answer.

13 ÷ 65 = 0.2

Our answer: 0.2 hours
