13 subtracted from twice a number gives 2. What is the numbera)4/7b)9/...
13-2a = 2
13-2 =2a
11=2a
11/2=a
a = 11/2
hence , option d is the answer
13 subtracted from twice a number gives 2. What is the numbera)4/7b)9/...
To find the number, let's assign a variable to represent the unknown number. Let's say the number is 'x'.
Let's translate the given information into an equation: "13 subtracted from twice a number gives 2".
Twice the number: 2x
Subtracting 13: 2x - 13
According to the question, this expression is equal to 2:
2x - 13 = 2
To find the value of x, we need to isolate it on one side of the equation.
So, let's solve for x step by step:
Step 1: Add 13 to both sides of the equation to eliminate the constant term on the left side:
2x - 13 + 13 = 2 + 13
2x = 15
Step 2: Divide both sides of the equation by 2 to isolate x:
(2x)/2 = 15/2
x = 15/2
Therefore, the number is 15/2, which is equivalent to 7.5.
As none of the given options match the correct answer, it seems there might be an error in the options provided. The correct answer should be 15/2 or 7.5, rather than option 'D' (11/2).
