Answer:
X=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
120(2x−2)=240
(120)(2x)+(120)(−2)=240(Distribute)
240x+−240=240
240x−240=240
Step 2: Add 240 to both sides.
240x−240+240=240+240
240x=480
Step 3: Divide both sides by 240.
240x/240=480/240
x=2

Which expression matches this situation?
A) 7a
B) a - 7
C) a + 7
D) 7 - a
Answer:
C) a + 7
Step-by-step explanation:
To correctly express this algebraic expression we just have to separate the terms, the age of Jose is oue incognita, and to know his age 7 years from now we just have to add the years that we know the age from today, and in this problem they ask us to create an expression that shows his age 7 years from now:
the age is expressed by "a", and 7 is the number of years from now that we want to know his age:
a+7
Is the correct expression.
