Choose the correct description of the graph of the compound inequality: (5 points)

Mathematics
1 answer:
skad [1K]4 years ago
4 0

Answer:

D

Step-by-step explanation:

Firstly,  

≤  or  ≥  means closed circle, and

<   or >  means open circle

Now, let's solve the compound inequality:

x - 1 ≤ 7

x ≤ 8

and

2x ≥ 22

x ≥ 11

This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"

Looking at the choices, D is right.

(3c+s)(100-20)/100=100  multiply both sides by 100

(3c+s)80=10000  divide both sides by 80

3c+s=125  subtract 3c from both sides...

s=125-3c....now let's look at the second situation...

(4c+2s)(100-40)/100=120  multiply both sides by 100

60(4c+2s)=12000  divide both sides by 60

4c+2s=200  divide both sides 2

2c+s=100 subtract 2c from both sides

s=100-2c, and from earlier we saw that s=125-3c, since s=s:

100-2c=125-3c  add 3c to both sides

100+c=125  subtract 100 from both sides

c=25, and since s=100-2c

s=50

So cds cost $25.00 and sweatshirts cost $50.00

Three hikers are dividing the costs of a hiking trip evenly. They bought two permits that cost $15 each, three tram tickets that
cestrela7 [59]

Each hiker owes $41 or 4100 cents for the hiking trip.

<u><em>Explanation</em></u>

Cost of each permit is $15. So, the cost of <u>two permits</u> will be: (\$15*2)= \$30

Cost of each tram ticket is $19. So, the cost of <u>three tickets</u> will be: (\$19*3)=\$ 57

Cost of <u>one can</u> of bear spray is $36.

So, the total cost of the hiking trip =\$30+\$57+\$36=\$123

As the <u>three hikers</u> are dividing the total costs of the trip <u>evenly</u>, so each hiker owes =\frac{\$123}{3}=\$41 or 4100 cents.
