Answer: C. (25,10)
Step-by-step explanation:
First change the 230 grams to kilograms or 1 kilogram to grams.
The units have to be the same.
Next set up a proportion.
Cross multiply to solve the proportion.
1 kg = 1000g
230 g/30 biscuits = 1000g/x biscuits
230x = 30(1000)
230x = 30000
divide both sides by 230
x =130 biscuits
Answer:
<u>For</u><u> </u><u>A</u>
• The equation above has a common bracket "(x + 1)". So, let's first factorise out that bracket:
• now in the second bracket, the common factor is x and 2.
• Final answer;
<u>For</u><u> </u><u>B</u>
• In the equation, the common bracket is (x + 2).
So let's first factorise it out:
• In the second major bracket, the common bracket is (x - 1). so factorise it out:
• Final answer:
