Answer:
The scale factor is 1 to 1.3
Step-by-step explanation:
Here, we want to get the scale factor
To get the scale factor, we divide corresponding sides by each other
That, we have that
9/7 = 1.3
Answer (2 answers):
x = -2/5, x = -14/5
Step-by-step explanation:
First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.
9|5x+8|=54
|5x+8| = 54/9
|5x+8| = 6
Remember how absolute values turn everything positive? For example
|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.
|5x+8| = 6 and |-(5x+8)| = 6
now solve the first equation.
(Just remove the absolute value sign and solve it normally)
5x+8 = 6
5x = -2
x = -2/5
Now solve the other equation
-(5x+8) = 6
-5x - 8 = 6
-5x = 14
x = -14/5
Total fish = 24 + 2 + 5 = 31
P(goldfish or angelfish) = 7/31
Answer: 7/31
The first property is commutative ( the numbers 38 and 677 are swapped over)
Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)
then the additive inverse ( 38 + (-38) = 0
and finally to get the 677 we use the additive identity property.
