# The joint of meat needs to be cooked for 30 minutes per 500 g plus an extra 20 minutes. How long will it take to cook a joint of meat weighting 2.5 kilo grand?

Let x = each 500 grams

Cooking time = 30x + 20

2.5 kg = 2500 grams
2500 / 5 = 5
X = 5

We put this in to the equation,
30*5 + 20 = 170 minutes

It will take 170 minutes to cook a joint of meat weighing 2.5 kilograms

15

Step-by-step explanation:

Given:

• 5a - 10b = 45
• b = 3,

Finding the value of a, solving the equation, considering the value of b=3:

• 5a - 10*3 = 45
• 5a = 45+30
• 5a= 75
• a= 75/5
• a= 15

Step-by-step explanation:

How many solutions are there to the equation below ? 8x+47 =8 (x+5)

First, distribute the right side.

8*(x + 5) = 8x + 40

Then, we write the whole equation:

8x + 47 = 8x + 40

Looking at it, we can subtract 8x from both sides, so that we're left with:

47 = 40

However, we obviously know that 47 is NOT equal to 40, so there is no solution for this equation.
