10^7 = 10,000,000
9.7x10^7 = 9.7x10,000,000
9.7x10,000,000 = 97,000,000
8.7x10^5 = 870,000
870,000x25 = 21,750,000
1. 21,750,000 new people are added after 25 years
2. The total population after 25 years is 118,750,000
Answer:
<ABC= 86 degrees
Step-by-step explanation:
Answer:
None
Step-by-step explanation:
We can eliminate the x's by add the 2 equations :
2y = 18
Divide both sides by 2 :
y = 9
Substitute this value into equation 1 to solve for x :
-3x + (9) = 6
Subtract 9 from both sides :
-3x = -3
Divide both sides by -3 :
x = 1
Substitute these values into equation 2 to check :
-3(1) + 6 = 12 ❌❌
So it has no solution
