A cyclist travels at an average speed of 20 km/h over a distance of 40 km.
How many hours does it take him?

Answers

Answer 1

Answer:

Given that speed(v) = 20km/h and time(t) = 50 min

We have to find distance (d)

First convert speed into m/s

v = (20*1000m)/(1*3600s)

v = (50/9) m/s

Now convert time into second

t = 50*60 = 3000 sec

As we know that

d = v*t = (50/9)*3000 = 50000/3

d = 16666.67m or 16.67km

Ans: 16666.67m or 16.67km

Step-by-step explanation:

Answer 2
Answer is equal to
16.67gm

−3x − 8y = 20 −5x + y = 19 solved by substitution

Answers

Delete as this is the wrong answer. Made a typo in the answer.

Answer:

x = [tex]\frac{-212}{3}[/tex]

y = 24

Step-by-step explanation:

-3x - 8y = 20  .... (1)

-5x + y = 19   .... (2)

What we can do is take the (2) equation

-5x + y = 19

and solve for y by adding 5x to both sides

y = 24

now that we have y we substitute it in for y in equation (1)

-3x - 8(24) = 20

-3x - 192 = 20

we want to solve for x so we need to get its self.

add 192 to both sides

-3x = 212

now we divide both sides by -3. It's going to be a fraction.

x = [tex]\frac{-212}{3}[/tex]

Answer:

x=-4

y=-1

Step-by-step explanation:

-3x-8y=20

-5x+y=19

rewrite for y:

y=19+5x

substitute y

-3x-8(19+5x)=20

-3x-152-40x=20

-3x-152-40x+152=20+152

-43x=172

-43x/-43=172/-43

x=-4

substitute x

-5(-4)+y=19

20+y=19

y=-1

check:

-3(-4)-8(-1)=20

12+8=20

-5(-4)+-1=19

20-1=19

Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.

Answers

The inequality that represents the possible values for the number of tables sold, tt, and the number of chairs sold, cc is $200cc + $650tt > $12,000.

What is the inequality ?

Here are inequality signs and what they mean:

> means greater than< means less than≥ means greater than or equal to ≤ less than or equal to

total cost of chairs sold + total cost of tables sold > $12,000

hauler and gio went to the store. they each purchased pop and snacks. hailey purchased 1 pop and 4 snacks and spent $14. gio purchased 2 pops and 2 snacks and spent $10. how much did the store charge each pop and snack? (write a system of equations and use elimination to solve.)

Answers

Answer:

Cost of pop = $2

Cost of snacks = $3

Step-by-step explanation:

Let

Cost of pop = x

Cost of snacks = y

Hauler

x + 4y = 14

Good

2x + 2y = 10

x + 4y = 14 (1)

2x + 2y = 10 (2)

Using elimination method

Multiply (1) by (2)

2x + 8y = 28 (3)

2x + 2y = 10 (2)

Subtract (2) from (3) to eliminate x

8y - 2y = 28 - 10

6y = 18

y = 18/6

y = $3

Substitute y = 3 into (1)

x + 4y = 14 (1)

x + 4(3) = 14

x + 12 = 14

x = 14 - 12

x = $2

Cost of pop = $2

Cost of snacks = $3
