Thinking the perimeter of the rectangle is 3x + 2 + x + 3x + 2 + X.

1 answer:

7 0

They are both right because the first expression is the perimeter but expanded in terms of length.The second expression is shortened to be a factor expression but they both represent the length.
The benefit of the first one is you can see how it’s expanded and plug the numbers in and the second one is more easy to plug in the numbers with ease.

The coffee shop used 52 pounds of Type A coffee.

Step-by-step explanation:

Cost of Type A coffee per pound = 5.25

Cost of Type B coffee per pound = 4.10

Total pounds used in blend = 142

Total cost = 642.00

Let,

x be the pounds of Type A coffee used

y be the pounds of Type B coffee used

According to given statement;

x+y=142 Eqn 1

5.25x+4.10y=642.00 Eqn 2

Multiplying Eqn 1 by 4.10

$4.10(x+y=142)\\4.10x+4.10y=582.20\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(5.25x+4.10y)-(4.10x+4.10y)=642.00-582.20\\5.25x+4.10y-4.10x-4.10y=59.80\\1.15x=59.80\\$

Dividing both sides by 1.15

$\frac{1.15x}{1.15}=\frac{59.80}{1.15}\\x=52\\$

The coffee shop used 52 pounds of Type A coffee.

Help this is really hars

We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope
