30 % because 55 - 30 is 25 and the nearst tenth is 30
Answer:
Step-by-step explanation:
Simplifying
2y + -3x = 18
Reorder the terms:
-3x + 2y = 18
Solving
-3x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-3x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
-3x + 0 = 18 + -2y
-3x = 18 + -2y
Divide each side by '-3'.
x = -6 + 0.6666666667y
Simplifying
x = -6 + 0.6666666667y
Ok so you would plug in 18 for the x so it would be 6(18)-12 and then 6x18 is 108 and 108-12=96 so your answer is 96
ANSWER
Find out the how much does it grow in 8 weeks
To proof
As given
A coral reef grows 0.17 m every week.
now for the 8 weeks
coral reef grows in the 8 weeks = 8× 0.17
= 1.36 m
As
1 meter = 1000 millimeter
To convert growth of coral reef in the millimeter
= 1.36 × 1000
= 1360 millimeter
Hence 1360 millimeter be the coral reef grows in 8 weeks
