Answer:
the answer is C) 7 and -7
Step-by-step explanation:
First you have to find out the cost for a single egg.
Since there are a dozen (12) eggs, you can divide the total cost by that.
1.12/12 ≈ 0.09.
Using the base cost of an egg, you can find out how much 3 eggs would cost.
0.09 x 3 = $0.27
Thickness of human hair - 9*10^1
Distance from earth to satellite - 2.8*10^13
Width of an apple - 1.1*10^1
Length of a tour bus - 4*10^0
Create some expressions.
1# number: x
2# number: 33x
3# number: 100 + x
this all equals to 310310 when added so
x+33x+(x+100) = 310310
Solve what you know first then rearrange it.
34x + x + 100 = 310310
35x = 310310-100
35x = 310210
x = 310210/35
x = 8863.142857
Substitute the x into the expressions made and you'll find the 2# and 3# number. You've already found the 1# number since it's only x.
