Let the number = x
x/2 + 12 = 46
x/2 = 46 - 12
x/2 = 34
x = 34 * 2
x = 68
So, your final answer is 68
Hope this helps!
Depends on the bag of Skittles you buy, but I assume you’re talking about a regular person 2.17 oz bag.
On the Target website, each 2.17 oz bag costs $0.89. 4.5 pounds is equivalent to 72 oz, so you would need about 33 bags of Skittles to have 4.5 pounds.
This means that $0.89 * 33 equals $29.37.

I put way too much effort into this...
The speed of current will be "4.5 mph" and the rate Pratap can row in still water will be "8.5 mph".
What does "speed" mean in mathematics?
- Speed is what it means. the speed of a change in an object's location in any direction.
- Speed is defined as the ratio of distance to the amount of time it took to cover that distance.
- Speed is a scalar quantity because it just has a direction and no magnitude.
Given:
Distance "26 miles" in time "2 hours".
Let,
Speed of water = y
Pratap speed when rowing in still water = x
As we know,
Speed = distance/time
then,
x + y = 26/2
x + y = 13
x = 13 - y
In return trip took him time "6.5 hours",
x - y = 26/6.5
x - y = 4
By substituting the value of "x", we get
13 - y - y = 4
13 - 2y = 4
2y = 13 - 4
2y = 9
y = 9/4 = 4.5 mph (Rate of the current)
By substituting the value of "y", we get
x = 13 - a
x = 13 - 4. 5 = 8.5 mph (Pratap can row in still water)

Answer:
D
Step-by-step explanation:
Substitute the value of x in each function and check if it's equal to it's corresponding value of y.
Correct me if I'm wrong. I hope it helps.
