Answer:
Opt. 1 -3 ≤ x ≤ 3
Step-by-step explanation:
Inequalities are regions, the attached picture shows us a region located between -3 and 3, the dots used are solid, this means that the value '3' is include in the region.
Hence the variable is narrowed to -3 and 3.
To answer that think of this as how many groups of 7/8 cups of salad are needed.
If Marion is with four friends, she need salad for five total people.
She will need five groups of 7/8 cups of salad.
This is represented as 5 x 7/8.
5 x 7/8 = 4 3/8 cups of salad
Answer:
The Answer is that one box of Oranges costs $7.13 and one box of Apples costs $12.99.
Step-by-step explanation:
Let o = oranges and a = apples
Equation 1:
3o + 14a = 203
Solve for o:
3o = 203 - 14a
o = 203/3 - 14/3a
o = 67.66 - 4.66a
Equation 2:
11o + 11a = 220
Substitute:
11(67.66 - 4.66a) + 11a = 220
744.26 - 51.26a + 11a = 220
-40.26a = 220 - 744.26
-40.36a = -524.26
a = -524.26/-40.36 = $12.99 for a box of Apples
Solve for oranges, o:
o = 67.66 - 4.66a
o = 67.66 - 4.66(12.99)
o = 67.66 - 60.53 = $7.13 for a box of Oranges
Hope this helps!! Have an Awesome day!!! :-)
Answer: 920
Step-by-step explanation:
828 divided by 0.9 will give you the answer
Since NO=NP (as seen by the 2 lines next to each other), we get
17=5x-6. Adding 6 to both sides, we get 23=5x and by dividing 5 on both sides we get x=23/5
