Answer:

Answer is:

x + y = 1,212

x - y = 518

Step-by-step explanation:

Given that the sum of two numbers is 1,212 and their difference is 518,

To get system of equations we could use to solve this problem, we assume the two number to be x and y.

i.e first number to be x, second number to be y.

Therefore:

Two numbers have a sum of 1,212 will be expressed as x + y = 1212

While, difference of 518 will be expressed as x - y = 518

Therefore:

x + y = 1,212

x - y = 518

P minus p over 6 = p over three plus 2
mel-nik [20]
The sum of opposites equals zero, which makes the equation zero over 6 equals p over 3 + 2 then you simplify the equation, multiply both sides by 3 which you will get 0=p+6 now we move variables to the left side and change its sign which is -p=6 so your answer will be p=-6 hope that helps you understand

Identify the percent increase in total sales and the percent increase in sales of trench coats. Then find which percent of
Ilya [14]

Answer:

Answer b: Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

First add all the sales for 2006, and do the same for the 2007 sales, so we can compare both total sales numbers:

For 2006 we have:

103+297+210+213+137 = 960 total sales

For 2007 we have:

127+223+210+285+259 =  1104 total sales

The percent increase is calculated as the difference between the final value minus the original value, divided by the original value and multiplied by 100:

For the total number of coats we have that the percent increase is: \frac{1104-960}{960} * 100= 15%

For the trench coats (which went from 103 sales tp 127 sales) we have the following percent increase: \frac{127-103}{103} * 100= 23.3%

Therefore, the percent increase in trench coats was larger than the percent increase in total sales by:

23.3 % - 15% = 8.3%

Can someone pls helppp
Dvinal [7]

Answer:

The answer is 64.

Step-by-step explanation:

Lets say the top row is <em>x</em> and the bottom row is <em>y</em>.

Since when <em>x</em> is 13 <em>y</em> is 104 and when <em>x</em> is 14 <em>y</em> is 112 that means the <em>y </em>value goes up by 8 every time.

when x=3: 16+8=24

when x=4: 24+8=32

when x=5: 32+8=40

when x=6: 40+8=48

when x=7: 48+8=56

when x=8: 56+8=64

Hope this helps you!!!!
