Pedro did KCF (Keychain flip)
Step 1&2 are correct as he did the process right.
So, he must of multiplied or simplified wrong
So, 4×8= 32
And 7×8=56
As you may have noticed he has gotten 20/50 instead of 32/56
Where Pedro messed up is step 3
HOPE THIS HELPER (:!

I'm newbie here
Step-by-step explanation:
Elimination Method.
4x + 6/y = 15 → step 1
6x - 8/y = 14 → step 2
so,
4x + 6/y = 15 |×6|
6x - 8/y = 14 |×4|
24x + 6/y(6) = 90
24x - 8/y(4) = 56
24x + 36/y = 90
24x - 32/y = 56
____________ _
68/y = 34
68 = 34y
34y = 68
y = 2
subsitution y = 2 to..
4x + 6/y = 15
4x + 6/2 = 15
4x + 3 = 15
4x = 12
x = 3
So, for x is 3, and for y is 2
Answer:
it is b
Step-by-step explanation:
Three geometric means between 3 and 48 are 6, 12 and 24.
Answer: 2 units
Step-by-step explanation:
Given that :
Length of of line segment (AB) = 18 Units
d = distance between point A and successive notch
Number of notches between point A and B = 9
If the length of line AB = 18 units and the number of notches between point A and B = 9
Then distance d, between successive tick marks :
Length of Line segment / number of notches or tick marks between A and B
= 18 units / 9
= 2 units.
Hence distance between tick marks on the number line is 2 units.
