Answer:
$14 per lb
Step-by-step explanation:
Given:
- Brand Y = $18 / lb
- Special Blend = $17 / lb
Let x be the price per lb of brand X coffee
3 lbs of brand X coffee + 9 lb of brand Y coffee = 12 lbs of special blend
⇒ 3x + 9(18) = 12(17)
⇒ 3x + 162 = 204
⇒ 3x = 42
⇒ x = 14
Therefore, brand X costs $14 per lb
Answer:
2x

Answer:
I’m not sure what this question is asking, but I’ll write an equation of this circle you are describing. Here, the x coordinate of the center is h, the y coordinate is k, and radius is r in the equation : (x-h)^2+(y-k)^2=r^2, meaning the equation in this situation is the following: (x-2)^2+(y-8)^2=9
Step-by-step explanation:
M5 is the same as m1 so it's 75°
Hey!
To simplify the equation provided we must first start off by grouping like terms.
<em>Original Equation :</em>
10 + 3c + 5d - 7c + d
<em>New Equation {Grouped Like Terms} :</em>
3c - 7c + 5d + d + 10
Now we add similar elements.
<em>Old Equation :</em>
3c - 7c + 5d + d + 10
<em>New Equation {Added Similar Elements} :</em>
-4c + 5d + d + 10
Next we add the other similtar elements.
<em>Old Equation :</em>
-4c + 5d + d + 10
<em>New Equation {Add Similar Elements} :</em>
-4c + 6d + 10
<em>So, this means that the equation 10 + 3c + 5d - 7c + d simplified is</em> -4c + 6d + 10.
Hope this helps!
