Micah did not explain the last step correctly. You cannot cross out a term from the numerator and denominator unless it is a factor. In other words, x² needed to be multiplied and not added in order to cross it out.
Answer:
70
Step-by-step explanation: Lets say x is the integer
5,600/x=80 is the same as
5,600÷x=80.
You should then rewrite it as 5,600÷80=x
Now simplify.
x=70
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion
7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)
7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function

where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
The general form of cosine function

where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : 0
In function, 
Amplitude : 
y-intercept : -1
Therefore, the correct options are B and D.
<h2>
6.7 hectometers is equal to "670 meters".</h2>
Step-by-step explanation:
We have,
6.7 hectometers
To convert 6.7 hectometers to meters.
We know that,
1 hectometer = 100 meters
⇒ 1 hm = 100 m
∴ 6.7 hectometers
= 6.7 × 100 meters
= 670 meters
∴ 6.7 hectometers (hm) = 670 meters (m)
Thus, 6.7 hectometers is equal to "670 meters".
