The answer to this is -4 and +13.
When you've got a negative number, this means that only one can be a negative number, and it is usually the smaller one.
-4*13= -52
-4+13= 9
Hope this helps :)
I'm only going to complete Part B. The other two are a bit easier and I believe you can do it! :D
Neighborhood A
----------------------------
Year 1: 30 increased by 20% = 6 more homes.
Year 2: 36 increased by 20% = 7.2 more homes ... 7 more homes. You cannot round in these types of problems.
Year 3: 43 increased by 20% = 8.6 ... 8 more homes.
Year 4: 51 increased by 20% = 10.2 ... 10 more homes.
Year 5: 61 increased by 20% = 12.2 ... 12 more homes.
At the end of 5 years Neighborhood A will have 73 homes in total.
Neighborhood B
---------------------------
Year 1: 45 +3 = 48
Year 2: 48 +3 = 51
Year 3: 51 +3 = 54
Year 4: 54 +3 = 57
Year 5: 57 +3= 60 homes
After 5 years Neighborhood B will have 60 homes.
Hope this helped! I will do Part A or Part C later if I have time and you still need assistance.
Answer:
The eye is made up of three layers: the outer layer called the fibrous tunic, which consists of the sclera and the cornea; the middle layer responsible for nourishment, called the vascular tunic, which consists of the iris, the choroid, and the ciliary body; and the inner layer of photoreceptors and neurons called the nervous tunic, which consists of the retina.
Answer:
Step-by-step explanation:
Red =x Blue = y
1) 4x + 6y = 180
2) x + y = 40
solve for x in eq. 2 and plug into eq. 1
2a) x=40-y
1a) 4(40-y) + 6y = 180
160-4y +6y = 180
2y=20
y=10
plug into eq. 2
x + 10 =40
x=30
30 red packages
;) maybe a late Christmas gift.. :D
