Answer:
Step-by-step explanation:
99x - 44y = -605
-99x + 63y = 738
19y = 133
y = 7
-9x + 28 = 55
-9x = 27
x = -3
(-3, 7)
Answer:
<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>
We know that
V = πr²h
400 = 22/7 × r² × 8
400 × 7 = 22 × 7r²
2800 = 154r²
2800/154 = r²
18 ≈ r²
4.2 = r

Answer:
Please check the explanation.
Step-by-step explanation:
Given that we have to determine the expressions which are equivalent to 20 percent of 150.
First, we need to determine what actually 20 percent of 150 really brings.
i.e
20% of 150 = 20/100 × 150
= 30
Thus,
20% of 150 = 30
Therefore, any expression that is equivalent to 30 will be included in the answer to this question.
Ok so to simplify 32^3/5, you will need to know the steps, so I'll tell u the step by step solution. ;D
So Step 1: You have to <span>Raise 32 to the 3rd power:
</span><span><span>1.1 </span> 32 = 2</span>⁵
(32)³ = (2⁵)³ = 2¹⁵
<span>the equation has ended on step 1, so now is:
</span><span> 2</span>¹⁵
<span>------
5
</span>
Now step 2:
Simplify it
(you can't simplify this equation but these is the steps you gotta do on other equations so I'm just giving an example.)
2¹⁵
------
5
So basically your final result is:
2¹⁵
------
5

Hope you understand it :D
