2x-2=x+45 <br> Can someone figure out the value of x?
Andre45 [30]

Answer:

<h3>x=47</h3>

Step-by-step explanation:

To solve this problem, first, you have to isolate x on one side of the equation. Isolate it on one side of the equation.

2x-2=x+45

2x-2+2=x+45+2 (First, add 2 from both sides.)

45+2 (Solve.)

45+2=47

2x=x+47

2x-x=x+47-x (Then, subtract x from both sides.)

47-x (Solve.)

47-x=47

x=47

In conclusion, the final answer is x=47.

Store A sells 11 bagels for 9.57 Store B sells bagels for 3.52. How do the unit rates compare?
Sloan [31]
First you put the numbers in this form:

11 Bagels = $9.57
________ _______
? Bagels   = $3.52

Now they look like fractions but you have to cross multiply them like this: 11 x $3.52 which makes $38.72 then you divide $38.72 by $9.57 which makes the answer that you have to find which is 4.04597701 or just to round 4 and then that will be your answer.
