Answer:
The equation made from this is:

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

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

**Answer:**

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**

__Correct choice is__**15**

**Answer:**

B. 15

**Step-by-step explanation:**

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.

Yes. One half of something is bigger than 1/3 of it. Think of it as a pie. The more pieces you cut it into, the smaller they are. Therefore, if you cut it in 2 pieces and take one, it will be bigger if it were cut into 3 pieces.

Yes. One third is lest then one half.
