Answer:
x>=4
Step-by-step explanation:
So if 3+x>=7 that means
x has to be 4 or greater equal to
x>=4
Solution:
Consider the following expression:
2.5 x 8(20+5)
Solving the expression inside the parentheses first, we obtain:
2.5 x 8(25)
this is equivalent to:
2.5 x 200
this is equivalent to:
500
so that, we can conclude that the correct answer is:
500
To find equivalent expressions,
distribute the first one and
factor the second one.
Sometimes true: when x = y it's true ; when x ≠ y it's not true.
