Answer:
x = 5
AB = 13
BC = 17
Step-by-step explanation:
So we have to make an equation;
(2x + 3) + (4x - 3) = 30
Collect like terms
6x = 30
Divide both sides by 6
x = 5
To find AB we have to plug in the value of x;
2x + 3 = 2(5) + 3
10 + 3 = 13
AB = 13
To find BC we also have to plug in the value of x;
4x - 3 = 4(5) - 3
20 - 3 = 17
BC = 17
Answer:
x=2
ab=7
bc=5
Step-by-step explanation:
because you do
2x+3 = 4x+3
-3 -3
2x=4x
-2x -2x
x = 2
2x2+3
4+3
=7
4x2-3
8-3
=5

Answer:
4 hours
Step-by-step explanation:
Write an equation
19 +1.5x < 15+2.75x
Subtarct 15 on both sides
4+1.5x<2.75x
subtract 1.5x on both sides
4< 1.25x
Divide 1.25 on each side
3.2<X
Since they on,y charge per hour so 4 hours
