Just subtract 6 from 84 until there are not any numbers left.
Answer:
Answer:
b. -75x+57=-75x+57
Step-by-step explanation:
If an equation after solving does not give the solution but give a true statement then the equation has infinitely many solution,
In option a.
57x+57=-75x-75
57x + 75x = -75 - 57
132x = -132
⇒ x = -1
i.e. it has only one solution,
In option b.
-75x+57=-75x+57
-75x + 75x = 57 - 57
0 = 0 ( True )
i.e. it has infinitely many solution.
In option c.
75x+57=-75x+57
75x + 75x = 57 - 57
150x = 0
⇒ x = 0
i.e. it has only one solution,
In option d.
-57x+57=-75x+75
-57x + 75x = 75 - 57
18x = 18
⇒ x = 1
i.e. it has only one solution.

We are given the following expression and we are to simplify it:
To make it easier to solve, we can also write this expression as:
Now we will cancel out the like terms to get:
Taking the square root of the terms to get:
Answer:
Distance: 25 miles
Step-by-step explanation:
we have distances between cities as follows:
From Portland to Tacoma: 120 miles
from Portland to Seattle: 145 miles
120+x=145 ⇒ x = 145 - 120 = 25 miles
from Tacoma to Seattle : 25 miles (according graph)
Answer: x-4 ≥12
Step-by-step explanation:
Hi, to answer this question we have to know what an inequality and a variable are:
Inequality: An inequality is a expression that compares two values, showing if one is less than, greater than, or simply not equal to another value.
Variable: is a symbol for a number that is unknown: they usually are letters (x;y).
An inequality that contains at least one variable could be:
x-4 ≥12
