Answer:
1) The mistake u made is in the work step 2 when u transposed 4 to the side of 12 you should have changed the sign. It should have been multiplication.
2) Just recheck it once.
So, x was 48
Step-by-step explanation:
Equation:
x/4 - 5 = 7
Transpose 5 first.
So,
x/4 = 7 + 5
(Remember to change the sign when u transpose 5 to the RHS)
So,
x/4 = 12
Transpose 4.
So,
x = 12 × 4
x = 48
Recheck,
Substitute x with 48
48/4 - 5 = 7
Let's check:
48/4 = 12
Now 12 - 5 = 7
So, 7 = 7
Hope it helps
Answer:
47/200
Step-by-step explanation:
to find experimental probability you have to find the number of times the desired outcome has happened the divide it by the total times the action has been performed. 19+13+15=47/200
