Erm what’s your question?
Step-by-step explanation:
Let
x
be the kg of coffee of brand A in the mix and
y
be the kg of coffee of brand B in the mix.
The total kg must be
50
.
x
+
y
=
50
The cost per kg of the mix must br
$
7.20
. For this, the total cost of the mix will be
6
x
+
8
y
, so the total cost per kg of the mix will be
6
x
+
8
y
50
.
6
x
+
8
y
50
=
7.20
Now that we have our two equations, we can solve.
6
x
+
8
y
=
7.20
⋅
50
6
x
+
8
y
=
360
From the first equation, we can multiply both sides by
6
to get:
6
x
+
6
y
=
300
Subtracting, we get:
2
y
=
60
y
=
30
Thus, we need
30
kg of brand B in our mix. This means that
50
−
30
=
20
kg will be of brand A.

Given
--- For the forest
-- --- For the forest
Required
Determine the area of the habitat
Since the distance between the animal's habitat is x mi on both sides;
The length and width of the habitat is:
The area is then calculated as follows;
Expand
Open Brackets
Reorder
Hence; the required polynomial for the habitat area is:
Answer:
C
Step-by-step explanation:
Consumed = 1500
Burned = 400
Calorie Count total = 1500 - 400 = 1100
His target is 1900, so he will need 1900 - 1100 = 800 calories to consume more
So, 1100 is NOT a viable solution because he will go over 1900 if that happens. Hence, C is the correct choice.
