The coffee merchant in mixed a coffee called Mississippi mud with a coffee called Pennsylvania pitch black to create a new coffe
ahrayia [7]

Answer:

4 pounds of mud

Step-by-step explanation:

Let the mud be added as x pounds.

Given:

Cost of 1 pound of mud = $ 1.50

∴ Cost of x pounds of mud = 1.5x

Cost of 1 pound of pitch black = $ 2

∴ Cost of 6 pounds of pitch black = 2\times 6=\$ 12

Amount of Texas T made = x+6 pounds.

Cost of 1 pound of Texas T = $ 1.80

∴ Cost of x+6 pounds of Texas T = 1.80(x+6)

Now, cost of Texas T will be equal to the sum of cost of mud and pitch black. This gives,

1.80(x+6)=1.5x+12\\1.8x+10.8=1.5x+12\\1.8x-1.5x=12-10.8\\0.3x=1.2\\x=\frac{1.2}{0.3}=4

Therefore, he used 4 pounds of mud coffee.

Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
nadya68 [22]

Option 1: y = -3x+3 is the right answer

Step-by-step explanation:

The slope-intercept form is given by:

y = mx+b

Here m is the slope and b is y-intercept

Given

m = -3

Point = (-1,6)

Putting the value of slope

y = -3x+b

To find the value of b, putting the given point (-1,6) in the equation

6 = -3(-1) +b\\6 = 3 + b\\b = 6-3\\b = 3

Putting the value of b in slope-intercept form

y = -3x+3

Hence,

Option 1: y = -3x+3 is the right answer

List the angles of triangle PQR from smallest to largest
Norma-Jean [14]
So in order for us to know which angle is the smallest and which one is the largest, take note that the largest angle is the opposite of the longest side, and the smallest angle is the opposite of the shortest side. So base on the given figure above, the smallest angle would be angle p, then next is angle q and the largest, therefore would be angle r. Hope this answer helps. So it is p,q,r.
