4 - 7x = 1 - 6x what is that​

Mathematics
1 answer:
DanielleElmas [232]3 years ago
4 0

Answer:

x = 3

Step-by-step explanation:

4 - 7x = 1 - 6x (Given)

4 - 1 - 7x = 1 - 1 - 6x (Subtraction Property of Equality)

3 - 7x = -6x (Simplify)

3 - 7x + 7x = -6x + 7x (Addition Property of Equality)

3 = x (Simplify)

x = 3 (Symmetric Property of Equality)

1. Andrew ran a marathon in about 1.56 x 10^4 s. (a) Write Andrews time in standard notation. (b) Evelyn ran a marathon in 4 h a
romanna [79]

Answer:

  • (a)  15,600 s
  • (b)  Evelyn

Step-by-step explanation:

(a) 1.56×10^4 = 1.56×10000 = 15,600

(b) There are 3600 seconds in an hour, so Andrew's time was

  15600 s/(3600 s/h) = 13/3 h = 4 1/3 h

1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.

Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train
ratelena [41]
Recall your d  = rt, distance = rate * time

so, keeping in mind that both trains are going at the same speed, say speed of "r" mph, after 212 hours A arrived at station A and after 4 hours, B arrived at station B.

now, the distance covered by train A is say "d", we know both stations are 585 miles apart, so, if train A covered "d" miles in those 212 hours, then train B covered the slack from 585 and d, that is "585 - d".

\bf \begin{array}{lccclll}&#10;&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\&#10;&------&------&------\\&#10;\textit{Train A}&d&r&212\\&#10;\textit{Train B}&585 - d&r&4&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;\boxed{d}=212r\\&#10;585-d=4r\\&#10;----------\\&#10;585-\boxed{212r}=4r&#10;\end{cases}&#10;\\\\\\&#10;585=216r\implies \cfrac{585}{216}=r\implies \cfrac{65}{24}=r\implies \stackrel{mph}{2\frac{17}{24}}=r
