2x + 3y = 1
y = x - 8
2x + 3y = 1
2x + 3(x-8) = 1
2x + 3x - 24 = 1
5x = 1 + 24
5x = 25
5x/5 = 25/5
x = 5
y = x - 8
y = 5 - 8
y = -3
x = 5 ; y = -3
2x + 3y = 1
2(5) + 3(-3) = 1
10 - 9 = 1
1 = 1

What is inequality?
Mathematical expressions with inequalities are those in which the two sides are not equal.
Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
The cost in dollars C(x) = 10 + 0.20x.
The revenue in dollars, R(x) = 0.50x.
For revenue to outpace cost
R(x) > C(x)
0.50x > 10 + 0.20x
0.50x - 0.20x > 10
0.30x > 10
x > 10/0.30
x > 33.333
Hence, For the income to exceed the cost, a minimum of 34 complete cups of lemonade must be sold.

0.50x > 10 + 0.20x
0.50x - 0.20x > 10
0.30x > 10
x > 10/0.30
x > 33.333
Therefore the minimum number of whole cups of lemonade that must be sold for the revenue to exceed the cost is 34.

Answer A
d :the distance in miles
t: the time in hours
v: the speed in miles/hours (vistesse)
d=v*t
==>d=40*4=160(mi)
d=55*x=160==>x=160/55=2.909090... (mi/(mi/h)=h)≈2.91(hours)
The time it would take to drive the same distance at 55 miles per hour is 2.91 hours.
What is the time needed to drive the same distance?
If time varies inversely with speed, as time increases, speed decreases. This means that the faster one travels, the lower the time it would take to reach the destination.
The equation that can be used to represent inverse relation is:
t = k / r
Where k is the constant of proportionality
4 = k/40
k = 160
160 / 55 = 2.91 hours

What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The exponential expression is given as,
⇒ (4)⁵
In the exponential expression aⁿ, the n is the exponent or power and a is the base of the expression.
Then in the exponential expression (4)⁵, the number 5 is the exponent or power and the number 4 is the base of the expression.
