Eight times a number increased by 9 exceeds 7 times the number by 15. Find the number.
Alborosie
Turn it into math terms bit by bit. let x be "a number"

8 times a number is 8×x

increased by 9 is +9

7 times a number is 7×x

exceeds is minus

by 15 is =15

now we put it together.

8 \times x + 9 - 7 \times x = 15
solve
8x + 9 - 7x = 15 \\ x + 9 = 15 \\ x = 6

Answer:

(0,0) is a solution to n=m and n=4m

Rasek [7]

Answer:

The median (half-above and half-below) could not have changed, because "corrected value was still lower than any other salary" does not change the position of that observation (still least) in the sorted list of salaries.

Mercury has a density of 13.6 g/cm^3 . What volume of mercury will have a mass of 47 grams? It’d be very helpful if someone coul
kondaur [170]

Density = mass / volume

Givens

Density = 13.6 grams / cm^3

mass = 47 grams.

Solve

D = m/v

13.6 = 47 / volume Multiply by volume

13.6 * volume = 47 Divide by 13.6

volume = 47 / 13.6

Volume = 3.46 ccs
