With this question

suppose p and q both represent prime numbers such that

5 x p + 7 x q= 109
find the value of the prime p.

on rearranging,

now, 109-7q should be a multiple of 5,

and for that, 7q must end with 9 or 4 as unit digit.

as q is prime,

let's try q=2,

(109-7×2)/5=95/5=19

which is a prime.

hence, P=19 and Q=2

we got lucky.

answer: options?

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
