Let the number be x
11 times the number : 11x
seven subtracted from the number : 11x - 7
Answer is -238:
11x - 7 = -238
11x = -231
x = 21
11x + 238
Answer:
x=4
Step-by-step explanation:
x/6 = 10/15
x/6 = 2/3
3x=12
P r o p o r t i o n s
3:4 = 7
3/198 = 7/x
solve for x using cross multiplying
3/198 = 7/x
198(7) = 3x
1386 = 3x
/3 /3
462 = x
Therefore, there are 462 workers.
Proof:
3/198 = 4/x
198(4) = 3x
792 = 3x
/3 /3
264 = x
264 + 198 = 462.
264 / 4 = 66
198 / 3 = 66
462 / 7 = 66
The ones that are divisible are 6, 3, 2, 11, and 4.
Greetings!
An item at full price is 100%, or by using the percentage formula:
If something is at 30% off, that means it is 70% of the original price (because minus the percentage from the 100%)
So by substituting the numbers into the percentage formula you end up with:
which is 0.7
So your answer would be D, 0.7!
Hope this helps!
