To find this answer, we subtract each of the like terms in the equation. 3x and 3x are like terms, -4y and 2y are like terms, and 7 and -5 are like terms. Now we subtract. 3x - 3x is 0, -4y - 2y is -6y, and 7 - (-5) is 12. That means that the result is -6y = 12, or B.

If i'm getting 20% commission from a monthly sale of $800000 what is my 30% in month of sale be?
Oksana_A [137]

Answer:

Your commission check for the 20% would be $160,000 and your 30% would be $240,000.

Step-by-step explanation:

To find each of these, multiply the total number of sales by the percentage of the commission.

$800,00*20% = $160,000

$800,000*30% = $240,000

likoan [24]

Answer:

no of kernels  pop = 4.34

Step-by-step explanation:

given data

kernels pop in 5 second  = 12

kernels are present = 235

solution

we get here kernels are pop at rate of here

kernels are pop at rate = 12  ÷  235  

kernels are pop at rate = 0.051063

and

we get here maximum kernels are remaining that is

maximum kernels remaining = 235 - 140

maximum kernels remaining = 85

so

no of kernels  pop in 5 second will be

no of kernels  pop = 0.051063   × 85

no of kernels  pop = 4.34
