First, simplify 2/8 to its smallest form, which is 1/4, or 25%
You could then right it as 23.25
<span>Simple. The two cyclists have covered a distance of 39 miles in 1.5 hours. 39 divided by 1.5 = 26, so 26kph combined speed. Then just divide 26 by 2 = 13kph, which is the average speed of each cyclist. Then add 2kph to the one cyclist and subtract 2kph from the other. One is going at 15kph, the other is going at 11kph. </span>
Answer:

Step-by-step explanation:
4x+3=28
4x=25
x=25/4
Answer:
-10<1
which means that -10 is less than 1
Answer:
2 - 5x² - 63
Step-by-step explanation:
Given
(2x² + 9)(x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
2x² (x² - 7) + 9(x² - 7) ← distribute both parenthesis
= 2 - 14x² + 9x² - 63 ← collect like terms
= 2 - 5x² - 63
