divide by 3.2
x=5
The value of the expression for the given values of a and b is -1
<h3>Evaluating an expression</h3>
From the question, we are to evaluate the given expression for the given values of a, b, and c
The given expression is
a + b
The given values are
a = 4,
b = -5,
and
c = -8
To evaluate the given expression for the given values of a and b, we will put the values of a and b into the expression,
That is,
a + b becomes
4 + -5
= 4 -5
= -1
Hence, the value of the expression for the given values of a and b is -1

Answer:
22x + 100 = 25x + 70, 10 yards
Step-by-step explanation:
Set the number of square yards of carpeting as x.
So, the cost of Country Carpets is: 22 * x + 100
And the cost of City Carpets is: 25 * x + 70.
In order for the costs to be the , the equations need to be equal.
22x + 100 = 25x + 70
Subtract 22x from both sides.
100 = 3x + 70
Subtract 70 from both sides.
3x = 30
x = 10
10 square yards
