Answer:
1115322
Step-by-step explanation:
In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.
Claimed statement is he worst is yet to come, with an earthquake 142,990 times as intense as the 1906 earthquake ready to hit San Francisco.
We need to find the magnitude of their claimed earthquake.
It can be calculated by simply multiplying 142,990 by 7.8 as follows :
The magnitude of claimed earthquake is 1115322
.
3x-12y = 5
-x+3y = 9
First step is to make the coefficient of either x or y same.
3x-12y = 5
(-x+3y = 9)3
3x-12y = 5
-3x+9y = 27
-4y = 32
y = -8
Answer:
4y-5xz has a degree of 2
Step-by-step explanation:
The degree of an expression the the largest degree of any of its terms.
The degree of a term is the sum of the exponents of the variables in that term.
4
y
=
4
y
1
has a degree of 1
5xz=5x1z1
has a degree of ( 1+1)=2
(5xz)
has a higher degree than
(4y)
Therefore the degree of the expression is the degree of
(5xz) , namely 2
Answer:
First one is 2.5
Step-by-step explanation:
7+7=14
21-14=7
7/2=3.5
3.5-1=2.5
