Spencer is 32 years younger than Jennifer. 3 years ago, Jennifer’s age was 3 times Spencer’s age. How old is Spencer now?

17

Step-by-step explanation:

The sentences 'Spencer is 32 years younger than Jennifer' can be modeled by x = y-32 (x representing spencer's age and y representing Jennifer's). The sentence '3 years ago, Jennifer's age was 3 times Spencer's age' can be modeled by the equation x-3 = 1/3(y-3). Solving the second equation for y gives you y = 3x-6. Substitute into the first equation to get x = (3x - 6) - 32. Solve for x, which represents Spencer's age, to get x = 17

5x+10 is the correct one

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
