<u>x</u><u> </u><u>=</u><u> </u><u>-</u><u>1</u><u>3</u><u>/</u><u>3</u><u> </u><u>and</u><u> </u><u>1</u>
<u>(</u><u>-</u><u>1</u><u>3</u><u>/</u><u>3</u><u>,</u><u> </u><u>1</u><u>4</u><u>/</u><u>3</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>1</u><u>,</u><u> </u><u>2</u><u>)</u>
Step-by-step explanation:
<u>f</u><u>o</u><u>r</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>(</u><u>a</u><u>)</u>
make x the subject of the formular:
<u>f</u><u>o</u><u>r</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>(</u><u>b</u><u>)</u>
<u></u>
substitute for x as 5 - 2y in equation (b):
therefore,
substitute for all values of y in equation (c):
<u>f</u><u>o</u><u>r</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>1</u><u>4</u><u>/</u><u>3</u><u>:</u>
<u>f</u><u>o</u><u>r</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>2</u><u>:</u>
Answer: C.)
Step-by-step explanation: Replace x with x and simplify 2x^2-5x+2fx
The fractions which cannbe formed are: 2/3, 3/2, 2/5, 5/2, 3/5 and 5/3.
Now, we find the products with the third number:
2/3*5= 10/3 = 3.33 > 2
3/2*5 = 15 >2= 7.5 > 2
2/5*3= 6/5 (rejected)
5/2*3 = 15/2 > 2
3/5*2= 6/5 (rejected)
5/3*2 = 15/2 = 7.5> 2
The circumference of a circle is pi • diamter
3.14 • 50 = 157 meters
