Answer:
NUMBER 2) x>_3/7
Step-by-step explanation:
-2(2-2x)-4(x+5) is less than or equal to -24
-2(2-2x)-4(x+5) <_ -24 Divide the expression by the #'s outside the ()
2-2x+x+5>_-3 This is the quotient from dividing it by -8 (-2 and -4)
(when you divide by a negative number, the signs flip)
7-x>_-3 Now, divide both sides by 7
-x>_-3/7 If you want, convert to a decimal. Lastly, divide by -1
x>_3/7
(5x^7y^2)(-4x^4y^5)=-20x^a y^b
<span>-20 x^11 y^7 = -20 x^a y^b </span>
<span>a = 11, b = 7 thus a: is you answer</span>
In this question, 10 people average running distance is 2.7miles. Then the sum of their running distance would be: 10 people * 2.7 miles/people= 27 miles.
The group then divided into 2, 4 people with 3 miles average and 6 people with unknown average. Since the people are same like the 10 people group, their total running distance would be the same. The calculation would be:
total distance = group1 * average1 + group2 * average2
27 miles= 4 people * 3 miles/people + 6 people* average2
6 people * average2 = 27 miles -12 miles = 15 miles
average2= 15 miles/6people= 2.5 miles/people
