Answer:

The answer is 215=55x+40 or 215=40+55x

Step-by-step explanation:

The reason it is that is because the plumber charges $55 for a service and he adds 40 for each hour he works so that is why this is the answer Remember the total bill cost 215 so that comes as the equation is equal to.

Hope that helps

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?

Pepsi [2]

X=4
Step 1: Simplify both sides of the equation.
1.5(x+4)-3=4.5(x-2)
(1.5)(x)+(1.5)(4)+ -3 =(4.5)(x)+(4.5)(-2)
(1.5x) + ( 6+-3) =4.5x - 9
(Combine like terms)
1.5x+3=4.5x-9

Step 2: Subtract 4.5x from both sides.
1.5x +3 -4.5x =4.5x=-9-4.5x-3x+3=-9

Step 3: Subtract 3 from both sides.
-3x+3-3=-9-3
-3x=12

Step 4: Divide both by -3
-3x/-3=-12/-3
X=4

What is the value of x?enter your answer in the box .

Katarina [22]

By pythagoras Theorem.

x² +12²=13²

=>x² +144 =169

=>x² =169-144=25

=>x=√25=5 unit.

Hence x=5 is your answer.

Hope it helps...
