9,899 = 206x
He divided by 206
He got 48.053 and rounded up to 49
My using the equation, we can see that he is correct.
You must connect all the letters to create the shape of a trapezoid
Answer:
<h2><em><u>62</u></em><em><u>.</u></em><em><u>2</u></em></h2>
Step-by-step explanation:
4n × 2 + 43
<em>[</em><em>By</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>n</em><em> </em><em>=</em><em> </em><em>2</em><em>.</em><em>4</em><em>]</em>
= (4 ×2.4) × 2 + 43
= 9.6 × 2 + 43
= 19.2 + 43
= <em><u>62.2 (Ans)</u></em>
Answer:
x = 1, y = -1
Step-by-step explanation:
If we have the two equations:
and
, we can look at which variable will be easiest to eliminate.
looks like it might be easy to get rid of, we just have to multiply
by 2 and y is gone (as -6y + 6y = 0).
So let's multiply the equation
by 2.

Now we can add these equations

------------------------

Dividing both sides by 5, we get
.
Now we can substitute x into an equation to find y.

Hope this helped!
