The words less than means we are subtracting 4.7 from something.
And the variable k is all that we are given so the algebraic expression for the given word expression is..
k - 4.7

The equation has no solution.
<h3>How to solve the equation?</h3>
The equation given is illustrated as:
3x-2y=3 .... i
6x-4y=1 ..... ii
Multiply equation i by 6
Multiply equation ii by 3
18x - 12y = 18
18x - 12y = 3
Subtract the equations.
This will give 0. Therefore, the equations gas no solution.

Answer:
A haircut costs $31
Coloring hair costs $93
Step-by-step explanation:
h = haircut
c = color
First equation: 1h + 2c = 217
Second equation: 2h + 1c = 155
Solve using elimination:
First, multiply both the equations so that they cancel the h's out:
First equation:
-1(2h + 1c = 155)
-2h - 1c = -155
Second equation:
2(1h + 2c = 217)
2h + 4c = 434
Then, put the equations together, and solve:
2h + 4c = 434
-2h - 1c = -155
3c = 279
c = 93
Find h:
2h + 1c = 155
2h + 1(93) = 155
2h + 93 = 155
2h = 62
h = 31
Hope this helped!
