Step-by-step explanation:
Sorry is it ok if I converted it into a simplified fraction?
<span>a=7b+8c+9d-10
8c = a - 7b - 9d + 10
c = (</span>a - 7b - 9d + 10) / 8
Answer:
The answer to your question is 9
Step-by-step explanation:
Data
Paramecium's length = 4.2 x 10⁻⁴ m
Ant's length = 3.8 x 10⁻³ m
Process
If we need to know how much longer is the ant than the paramecium, we just need to divide the ant's length by the paramecium's length.
Times that the length of the ant is longer than the paramecium length =

Simplification and result
9
2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4
a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0
the same can be done for the second one 2+k-8
make it 2+k-8=0
move the k to get it alone so subtract k from both sides
2-8=-1k
-6 = -1K
you can divide by K to make K=6
plug in 2+6-8=0
0=0
