Answer:
Step-by-stepapex answer to the left of 9.9 and to the right of 9.3 explanation:
Answer:
C. (1, -3)
Step-by-step explanation:
<em>My thought process: Guess and check by plugging in each ordered pair.</em>
A) -2 < 3(-3) +1
-2 < -8 FALSE
B) 14 < 3(3) + 1
14 < 10 FALSE
C) -3 < 3(1) + 1
-3 < 4 TRUE
Based on the given situation, if x is number of kilograms of lobster, you can write the following expressions:
51 + 5x cost in the first restaurant
33 + 8x cost in the second restaurant
In order to determine the value of x which makes the cost the same in both restaurants, equal the previous expressions and solve for x:
51 + 5x = 33 + 8x subtract 33 both sides and 5x subtract both sides
51 - 33 = 8x - 5x simplify
18 = 3x divide by 3 both sides
18/3 = x
6 = x
x = 6
Hence, the weight of the lobster is 6 kg.
The cost of the dinner is:
51 + 5(6) = 51 + 30 = 81
Hence, the cost of the dinner is $81
Lets look at the information we have:-
6.8 pounds on Sunday
8.75 pounds on Monday
How many pounds did he collect together on these 2 days?
Add:-
6.8 + 8.75 = 15.55
Dan collected 15.55 pounds of aluminum on these 2 days.
CHECK OUR WORK:-
15.55 - 8.75 = 6.8
We were RIGHT!!
So, Dan collected 15.55 pounds of aluminum on these 2 days.
Hope I helped ya!! xD
