Well, if he walked one and three fourths miles five times, all you have to do is multiply one and three fourths and five to get your answer.

$1 \frac{3}{4}*5 \\ \\ \frac{7}{4}* \frac{5}{1} \\ \\ \frac{7*5}{4*1} \\ \\ \frac{35}{4} =8 \frac{3}{4}$

Without multiplying, tell which is greater: 4/5 x 45 or 2/3 x 45. Explain.

Aloiza [94]

Answer: It is 4/5 x 45

Step-by-step explanation: Hope i helped please mark brainliest!

I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30

therefore, 4/5 x 45 is greater!

also, if not multiplying 0.8(5/4) is greater than 0.667(2/3). Therefore, 4/5 is greater than 2/3.

Find all complex solutions of 7x^2-7x+3=0

Sedaia [141]

Answer:

The complex solutions are

$x = (\frac{7-\sqrt{35} i }{42} , ) x = \frac{7 + \sqrt{35} i }{42})$

Step-by-step explanation:

Step(i):-

Given equation 7 x² - 7 x +3=0

$x = (\frac{-b -\sqrt{b^{2}-4ac } }{2ac} , \frac{-b +\sqrt{b^{2}-4ac } }{2ac})$

Given standard equation

a x² +b x +c =0

a = 7 , b= -7 and c=3

Step(ii):-

$x = (\frac{-(-7) -\sqrt{(-7)^{2}-4(7)(3) } }{2(7)(3)} , \frac{-(-7) +\sqrt{(-7)^{2}-4(7)(3) } }{2(7)(3)})$

$x = (\frac{7-\sqrt{(49-84 } }{42} , \frac{7 +\sqrt{(49-84 } }{42})$

$x = (\frac{7-\sqrt{35i^{2} } }{42} , \frac{7 + \sqrt{35i^{2} } }{42})$

$x = (\frac{7-\sqrt{35} i }{42} , \frac{7 + \sqrt{35} i }{42})$

Write a compound inequality that represents each situation. Graph your solution. On a road in the city of Rochester, the maximum

drek231 [11]

Let s represent speed.

$20 \le s \le 50$

To graph it, draw a number line. Show zero, 20, 50 and arrowheads at both ends. Draw closed circles at 20 and 50 and shade in between.
