a) Given, 

Total marks in English = 90

Marks scored by James = 60

Therefore, 

Percentage of marks scored

$= \frac{60}{90} \times 100$

= 66.67% (approx. )

Then,

Total marks in Science = 150

Marks scored by James = 78

Therefore, 

Percentage of marks scored

$= \frac{78}{150} \times 100$

= 52%

At last,

Total marks in Maths = 120

Marks scored by James = 75

Therefore, 

Percentage of marks scored

$= \frac{75}{120} \times 100$

= 62.50%

b) In English test  James scored highest percentage.

The point (1,1) is the image under the translation (x,y)-> (x+3,y-3). What is the preimage of this point?

wel

Answer:

(-2,4)

Step-by-step explanation:

$\text{pre-image}->\text{image}$

$(x,y)->(x+3,y-3)$

$(x,y)->(1,1)$

This implies $(x+3,y-3)=(1,1)$ .

This means $x+3=1$ and $y-3=1$ .

Subtract 3 on both sides for first equation: $x=1-3=-2$ .

Add 3 on both sides for the second equation: $y=1+3=4$ .

So the pre-image (x,y) is (-2,4) if the image is (1,1).

Let's check:

$(x,y)->(x+3,y-3)$

$(-2,4)->(-2+3,4-3)$

$(-2,4)->(1,1)$

So the solution has been checked and verified.
