Step-by-step explanation:

1.a. 5 cars carry 375 people

Then,

I car carries=(375/5)=75 people

Therefore,

No. of cars required to carry 675 people=(675/75)

= 9 cars

b. Let the two numbers be 7x and 3x,

Then according to question,

7x-3x=36

4x=36

x=(36/4)=9

Therefore,

Bigger number=(7*9)=84

c. ⅓(2y-1)=3

(2y-1)=3*3

2y=9-1

y=8/2=4

d.i. No, because the 75° angle doesn't correspond to the same angle on the two triangles.

ii. In the ΔABE & ΔCDE,

AB=CD (given)

BE=CE (given)

∠BEA=∠CED (vertically opposite angles)

Therefore,

ΔABE≅ΔCDE (by SAS)

2.a. Please check the question. Anyone who is older than you cannot be the same age as you at any particular time.

b. In ΔABO & ΔAOC,

∠BAO=∠CAO (because OA bisects angle A)

AO=AO (common)

∠OBA=∠OCA (given)

So,

ΔABO≅ΔAOC (by ASA)

Therefore,

OB=OC (by CPCT)

c.i. In ΔABD & ΔACD,

AB=AC (given)

∠ABD=∠ADC (given)

AD=AD (common)

ii. ΔABD≅ΔACD (by SAS) (proved above)

iii. BD=BC (by CPCT)

Therefore,

D is mid-point of BC
