Alexandera=a
imani=i
a is 8 more than i or
a=8+i
the sum of the 2 numbers is 50 or
a+i=50
a=8+i
so subsitute 8+i for a in a+i=50
8+i+i=50
8+2i=50
subtract 8 from both sides
2i=42
divide both sides by 2
i=21
subsiutte into a=8+i
a=8+21
a=29
a=29
i=21
There is no answer because there cannot be one to one function inverse.

Answer:
1/3 <x
Step-by-step explanation:
2x + 4 < 5x + 3
Subtract 2x from each side
2x-2x + 4 < 5x-2x + 3
4 < 3x+3
Subtract 3 from each side
4-3 <3x-3+3
1 <3x
Divide each side by 3
1/3 <3x/3
1/3 <x
Answer:
4 kg of sugar would contain
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x

Solve for x. Cross multiply.



Divide both sides by 3


4 kg of sugar would contain
crystals.
