The sum of Jim's weight and Bob's weight is 180 pounds. If you subtract Jim's weight from Bob's weight, you get half of Bob's we
Furkat [3]

Answer:

120 pounds

Step-by-step explanation:

We can use systems of equations to solve this problem. Assuming j is Jim's weight and b is Bob's weight, the equations are:

j + b = 180

b - j = 1/2b

Let's get b - j = 1/2b into standard form (b, then j, then the equal sign, then the constant.)

b - j = \frac{b}{2}\\\frac{b}{2} - j = 0

Now we can solve using the process of elimination.

b + j = 180\\\\\frac{b}{2} - j = 0\\\\b + \frac{b}{2} = 180\\\\b + b \cdot 2 = 180\cdot 2\\3b = 360\\b = 120

Now we know how much Bob weighs, for fun, let's find Jim's weight by substituting into the equation.

120 + j = 180\\j = 180-120\\j = 60

So Bob weighs 120 pounds and Jim weight 60 pounds.

Hope this helped!

Textbooks are exempted from PST in Ontario. If the total cost of a book
Andrei [34K]

Answer:

4.24

Step-by-step explanation:

Total price = price of the book + 5% of the price of the book

T = total price   P = price of the book G = GST

T = P + G

and

G = 5% of P = 0.05P

therefore

T = P + 5%P = 1P + 0,05P = 1.05P

P = T/1.05 = 89/1.05 ≅ 84.76 (it is 84.7619047619)

G = 89 - 84.76 = 4.24

André solves the following system of equations by elimination.
Vaselesa [24]
Although the question is incomplete, I have seen it before.

The equations are:
3a + 6b = 12
-3a + 6b = -12

Adding the equations, we get:

12b = 0
And b = 0
