We are told to solve for n given the equation 3(n + 4) = -6 + 15n. We can solve for n by first using the distributive property, which gives us 3n + 12 = -6 + 15n. Now, subtract 15n from both sides, giving us -12n + 12 = -6. Next, subtract 12 from both sides to get -12n = -18. Now, divide both sides by -12 to get n = 18/12, or 3/2 when simplified. Therefore, the value of n in the equation 3(n + 4) = -6 + 15n is 3/2. Hope this helped!

Alexandra [31]

Answer:

90 days

Step-by-step explanation:

Let the rate per day for the 30 days period be x

Given that the rate drops to 1/3 of the rate used in 30 days period, it means that the new rate

= 1/3 x

If at a rate of x, the full tank runs for 30 days

at a rate of 1/3 x, the full tank would run for

= x/ (1/3 x) * 30 days

= 3 * 30 days

= 90 days

At the new rate, the full tank of oil will last for 90 days

Directed line segment DE has endpoints D(-4,-2) and E(1,8). Point F divides DE such that DF:FE is 3:2What are the coordinates of

VMariaS [17]

The Solution.

The given points are

$D(-4,-2)\text{ and E(1,8)}$

The formula is

$\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}$

In this case,

$m=3,n=2$

Therefore,

$\begin{gathered} (\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}) \\ =(\frac{3(1)+_{}2(-4)_{}}{3+2}_{},\frac{3(8)_{}+2(-2)_{}}{3+2}) \\ \end{gathered}$ $=(\frac{3-8}{5},\frac{24-4}{5})=(-\frac{5}{5},\frac{20}{5})$ $=(-1,4)$

Hence, the correct answer is (-1, 4) (option 3)

N aumentado en un 25%

Shkiper50 [21]

Answer:

1.25 * N

Step-by-step explanation:

We have to increase N by 25%.

The first thing is to say how the percentage works in these cases, N would be our 100% and the increase would be 25% in this case, therefore, the initial value must be added (that is, N, 100%) and to that if add 25% of the initial value (that is, + 25% N).

Thus:

100% * N + 25% * N = N * (100% + 25%)

N * (125%) = 1.25 * N

So to increase N is 25% it would be 1.25 * N
