Vinvika [58]

w+2x=16 ⇒ w=16-2x

x+2w=14 x+2(16-2x)=14

x+32-4x=14

-3x=14-32

-3x=-18 /:(-3)

x=6

w=16-2x=16-2·6=16-12=4

2y+w=-6 ⇒ 2y+4=-6

2y=-6-4

2y=-10 /:2

y=-5

A Japanese bullet train travels 558 miles per 3 hours A. What is the rate B. How far does the train travel in 1 hour WHO EVER A

Delicious77 [7]

Answer:

Step-by-step explanation:

Remark

The rate is going to be the same as the distance travelled in 1 hour. The units will be different.

Formula

d = r * t

Givens

d = 558 miles

t = 3 hours

Problem A

r = d / t

r = 558/ 3 = 186 miles / hr

Problem B

Givens

r = 186 miles / hour

t = 1 hour

d = ?

Solution

d = 186 mi/hr * 1 hr

d = 186 miles

This looks really trivial, but it's not. You have to learn to see the difference between a number and its units. It's not very often that the numbers will be the same, but if the units differ, then it is an entirely different question.
