Could i get some help with this problem. 7(x-3)=49

Answers

7x-21=49, 49-21= 28/7= x= 4

Answer:

x = 10

Step-by-step explanation:

- The first thing to do is open parentheses:

7 (x - 3) = 49

7x - 21 = 49

- Then add 21 to each side:

7x - 21 = 49

7x = 70

- Now divide each side by 7:

7x = 70

x = 10

Mr. Wu rides his bike at 6 mph to the bus station. He then rides the bus to work, averaging 30 mph.

If he spends 20 minutes less time on bus than on the bike, and the
distance from his house to work is 26 miles, what is the distance from
his house to bus station?

Fill out the information in the table for your convenience. Write the
equation. Solve. Show your work. Check your work

Answers

Answer:

26 mi

Step-by-step explanation:

Convert 20 min to hrs: 20/60 = 1/3 hr

:

Let t = time on the bike

then

t-(1/3) = time on the bus

:

Write a dist equation Dist = speed * time:

:

Bike dist + bus dist = 26 mi

 

6t + 30[t-(1/3)] = 26

:

6t + 30t - 10 = 26

36t = 26 + 10

36t = 36

t = 1 hr on the bike

:

6 mph for 1 h = 6 mi from house to the bus station

:

:

Check solution by finding the distance

6(1) + 30(2/3) =

6 + 20 = 26 mi
