Answer:
AC = 25 units
Step-by-step explanation:
Given ∠ A = ∠ C then the triangle is isosceles and BC = AB , that is
7x - 1 = 5x + 5 ( subtract 5x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Then
AC = 6x + 7 = 6(3) + 7 = 18 + 7 = 25 units
3x + 2y = 12
(x, y) = (__, 0)
3x + (2 x 0) = 12
3x + 0 = 12
3x = 12
x = 4
(4, 0)
Now you see when you use a model it is harder kepause........
<span>of the task , we know that :
</span>
profit netto = $ 6100
<span>influenza students = 7
</span>hourly rate for one lesson of the French language = $45
<span>we do not know about
</span>
profit brutto = ? <span>denoted as x
</span><span>the amount collected lessons
for one student = ? denoted as y
x = $6100 + $200
