Answer:
18 units
Step-by-step explanation:
The base is 7-4 = 3 units
The height is 8 - 2 = 6 units
P = 2(b+h)
P = 2( 3+6)
P = 2(9)
P = 18
Hmmm..... let us try again...but this time with a different strategy,.... by the graph method.
The system is
3x + 4y =96
2x + 5y = 99.
We find solutions of each system and then plot them on a graph.
Solutions for equation 1 = (2, 22.5) and (30, 0)
Solutions for equation 2 = (49.5 , 0) and (1, 19.4)
Now, we plot both the equations on a graph paper and note its intersecting point.
Experimentally, we find the intersecting point is (12,15)
Thus, the solution for the system is x = 12 , y = 15.
Thus, we arrive at the conclusion 1 shirt costs 12$
1 cap costs 15$
50 degrees because if you add up all the angles and subtracts from 180 you get 50
Answer:
- 1 1/3=k
Step-by-step explanation:
8 / 5 = -1 1/5k
To isolate the K we need to divide each side by -1 1/5
8/5 / -1 1/5 =k
now we can use kcf to divide
8/5 x -5/6 =k
multiply straight across
-40/30 =k
simplify
-4/3 = -1 1/3 =k
