Answer:
-7
Step-by-step explanation:
Let the number be x
So we get equation : 3x + 8 = -13
Thus, 3x = -13-8 = -21
So, x = (-21)/3
Hence the required number is -7
Answer:
C. 12 (2m - p + 6)
Step-by-step explanation:
just distribute

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
