Answer:
Step-by-step explanation:
<u>x is side of right triangle with other sides:</u>
<u>Then x is:</u>
- x² = √20² - 4²
- x² = 4
- x = 2
Answer:
cost price=$150,000
selling price =$154,000
profit= $154,000-$150,000=$4,000
Therfore Percentage Profit= 4,000÷15,000×100=2.7%
Percentage Profit =2.7%
You must multiply 5x-3 with 5, then you will get
25x-15 = 1
25x = 1+15
25x = 16
x = 0.64
Answer:
One solution, x = 8/9
Step-by-step explanation:
One way to solve this is to take one equation and substitute into the other and then solve. So, take y=5(x-4) and put that into the other equation.
4x + 12 = -y
4x + 12 = -(5(x-4)) <--- substitution here
4x + 12 = -5(x-4)
4x + 12 = -5x + 20 <-- simplifying
4x + 5x = 20 - 12
9x = 8
x = 8/9
Answer:
Step-by-step explanation:
for two matrices A, B to be Similar, then A = SBS⁻¹
A=SBS−1⟹trace(A)=trace((SB)(S−1))=trace((S−1)(SB))=trace((SS−1)B)=trace(B)
