To solve for b, the first step would be to simplify the fraction 1/2bh and turn it into bh/2.
To solve for h, the first step would be the same as the first step to solve for b.

<em>x = 25°</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>We know : </em><em><u> the sum of the measures of any triangle is 180 degrees</u></em><em>.</em>
<em>A + B + C = 180°</em>
<em>(3x - 13) + (2x + 4) + (180 - 116) = 180</em>
<em>5x - 13 + 4 + 64 = 180</em>
<em>5x = 180 - 64 - 4 + 13</em>
<em>5x = 125</em>
<em>x = 125 : 5</em>
<em>x = 25°</em>
<em>Good luck !</em>
Answer:
The cost of cinnamon tea per pound is $2.5
The cost of spice tea per pound is $ 3
Step-by-step explanation:
Let the cost of cinnamon tea per pound be x
Let the cost of spice tea per pound be y
Then according to the question:
A merchant mixed 8 lb of a cinnamon tea with 6 lb of spice tea. and its cost is $38
Then,
8x + 6y = 38-------------------------------(1)
A second mixture included 16 lb of the cinnamon tea and 10 lb of the spice tea. The 26-pound mixture cost $70
16x + 10y = 70----------------------------(2)
To Solving (1) and (2)
Multiply (1) by 2 then
16x + 12y = 76-----------------------------(3)
Subtracting (2) from (3)
16x + 12y = 76
16x + 10y = 70
------------------------
0x + 2y = 6
-------------------------
y = 3
On substituting y value in eq(1)
8x + 6(3) = 38
8 x + 18 = 38
8x = 38 -18
8x = 20
x = 2.5
