Step-by-step explanation:
Let the present age of father = x years
and the present age of son = y years
according to the first condition
x + y =44 ........(i)
according to the second condition
x+8 = 2(y+8)
or x+ 8 = 2y + 16
or x- 2y = 8 ............(ii)
solve the equation (i) & (ii) we get
x + y =44
x- 2y = 8
••••••••••••••••••••••••
3y = 36
or y = 12
put the value of y in equation (i), we get
x + 12 =44
or x = 32
so the present age of father = x =32 years
and the present age of son = y = 12 years.
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:
Answer:11/4 ÷31/2= 11/4 * 2/31 [2 and 4 get cancelled] 11/2 * 1/31 = 11/62

Answer:
Step-by-step explanation:
First, you want to do inverse operations like I said on the last equation
Just divide -4 with 64
You have to flip the inequality sign because you divided by a negative
Answer: g ≥ -16
Now what is greater than or equal to -16?
Answer =
-16
-11
-6
-13
(3-6)-p
It says your subtracting 6 from 3 which is (3-6) and it says "then" that's why we put parentheses and then put "-p"
