What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?

AnnZ [28]

The value of n in given proportion is 16

Solution:

We have to find the value of "n" in the proportion

Given proportion is:

$\frac{n}{28} = \frac{4}{7}$

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

$->\frac{n}{28} = \frac{4}{7}$

$-> 7 * n = 4 * 28$

$-> n = \frac{4 * 28}{7}$

$-> n = 4 * 4 = 16$

Thus the value of n in given proportion is 16

Three lorries each making five trips per day transport 2500 crates from a factory to a distributor in two days .how many lorries

elixir [45]

Step-by-step explanation:

3×5×2 = 30 lorry trips to deliver 2,500 crates.

3 lorries, 5 trips per day, 2 days

that means that one lorry trip transports

2,500 / 30 = 250/3 = 83.33333... crates = 83 1/3 crates.

now we need x lorries each making 6 trips per day in 1 day (so, 6 trips, period) to transport 10,000 crates.

that looks like

x × 6 × 83.33333... = 10,000

x × 6 × 83 1/3 = 10,000

x × (6×83 + 6 × 1/3) = 10,000

x × (498 + 2) = 10,000

500x = 10,000

x = 20

so, we need 20 lorries each doing 6 trips in one day to transport 10,000 crates in one day.

these are altogether 20×6 = 120 lorry trips.

that is 4 times the number of the original scenario (30 trips).

and logically, when doing 4 times the work, we achieve 4 times the result (10,000 crates instead of 2,500).
