8/x=14/7 what does x equal

Veronika [31]

Answer:

when you have two fractions that equal each other you want to solve by using cross multiply

What cross multiply is, is when you multiply diagonally so:

8/x=14/7

you would take 14*x and 8*7

14x=56 (you would then divide each side by 14)

x=4 (14/14=1, 56/14=4)

8/4=14/7

To check your work you could simplify

8/4=2

14/7=2

2=2, which is true

x=4

Hope this helps ;)

An elephant can run of a mile in 36 seconds. At this rate, which expression can be used to determine how fast an elephant runs i

Mice21 [21]

Answer:

The expression that can be used to determine how fast an elephant runs in miles per hour is 100 miles per hour

Solution:

Given that,

Distance covered by an elephant in 36 seconds is equal to 1 mile

Therefore, distance covered by the elephant in 1 second is $\frac{1}{36}$ mile

Therefore, distance covered by the elephant in 60 seconds (60 seconds = 1 minute) is

$\frac{1}{36} \times 60=\frac{5}{3} \text { miles }$

Therefore, distance covered by the elephant in 60 minute (60 minute = 1 hour) is

$\frac{5}{3} \times 60=100 \text { miles per hour }$

Hence the expression that can be used to determine how fast an elephant runs in miles per hour is 100 miles per hour
