Well, if you take x to be 25 seconds, there are 2.4x in 1min. So, that multiplied by 60, would be 144x. Therefore, 1/4 multiplied by 144x should be the answer.

The way we work this out is by working out the amount of lots of 25 seconds in an hour, and then multiply it by that 1/4 of an hour. 1 hour has 60 minutes, and each minute has 60 seconds, so 1 x 60 x 60 = 3600 = the number of seconds in an hour.

3600/25 = 144. Therefore there are 144 lots of 25 seconds in an hour. If the deer runs 1/4 a mile in 25 seconds, then we just have to do 144 x 1/4 and it will give us the answer.

144 x 1/4 = 36. Therefore the deer can run 36 miles per hour.

If you want to express this all in one equation, we can write it as:

((60 x 60)/25) x 1/4 = 36

Hope this helped :))

kodGreya [7K]
The volume of a cone is
\pi {r}^{2} (h \div 3)
since V=65.94 and r=3, you just plug it in and solve for h which results to 6.996cm

Which equation shows the result of substituting and expression for y from the first equation into the second equation for the gi
krek1111 [17]

Answer:

x-2x = -3 and x = 3

Step-by-step explanation:

Given the expression

y=x+5.... 1

y-2x=2.... 2

Substituting the first equation into the second we will have;

From 2;

y -2x = 2

x+5-2x = 2

x-2x +5 = 2

x-2x = 2-5

x-2x = -3

-x =-3

x =3

Hence the required equation is x-2x = -3 and x = 3
