1x + 1y = 100....multiply by -3/8
3/8x + 7/8y = 2000
no need to multiply the other equation by anything....the x's will cancel because one will be -3/8x and one will be 3/8x
Answer:
They are 192 km apart.
Step-by-step explanation:
? = unknown value
We can use the equation
? km = ?cm * 8
Or ratio
1/8 (What do you multiply 1 by to get to 8? 8. 1 is how many cm there are so if there are 24 cm then we multiply that by 8 as well.)
We have to multiply 24cm by 8 because of the ratio 1:8, 24 times 8 is 192.
48 = 12*4
12 = 12*1
The greatest common factor of 12 and 48 is 12
Answer:
10
Step-by-step explanation:
Firstly, find the value of f(3)
⇒ 
[sub in 3]
⇒ 
[multiply by 2 and add 1]
Now, find g(f(3))
⇒ 
[sub in 7]
⇒ 
[multiply by 3 and subtract 1]
⇒ 
[divide by 2]
