3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants
3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
Answer:
Angle Bisector Construction
Step-by-step explanation:
The line in the center of the angle is bisecting said angle.
First you rewrite all the expressions like this:
8x+4=(2x+12)+(2x+4)
then you solve and get:
x=3
to solve for AC, you have to solve 8x+4 by replacing x with 3
8x+4 would be rewritten as:
8(3)+4
AC=28
Answer:
<h2>S = 11.4</h2>
Step-by-step explanation:
To find s we use the cosine rule
That's
s² = SU² + ST² - 2(SU)(ST) cos S
From the question
SU = 5
ST = 13
S = 60°
Substituting the values into the expression we have
s² = 5² + 13² - 2(5)(13) cos 60
s² = 25 + 169 - 130cos 60
s² = 194 - 65
s² = 129
Find the square root of both sides
s= √129
s = 11.357816
We have the final answer as
<h3>s = 11.4 to the nearest tenth</h3>
