A father is 25 years older than his son. 10 years ago, he was six times as old his son. What are their present ages?​
RoseWind [281]

Answer:

Present age of son = 15 years

& Present age of father = 40 years

Step-by-step explanation:

  • Let the son's present age be x years

  • -> Father's present age = (x + 25) years

  • 10 years ago:
  • Son's age = (x - 10) years

  • Father's age = (x +25 -10) = (x +15) years

  • It is given that: 10 years ago father was six times as old as his son

  • -> x + 15 = 6(x - 10)

  • -> x + 15 = 6x - 60

  • -> x- 6x = - 60 -15

  • -> -5x = - 75

  • -> x = -75/(-5)

  • -> x = 15

  • -> x + 25 = 15 + 25 = 40

  • -> Present age of son = 15 years

  • & Present age of father = 40 years.

Select the a statement that represents 35 equals 5×7 is it A pat collected five cars one year and seven cars the next year ,b fl
Lina20 [59]

The answer is B, Pat collected five cars each year for seven years (There were typos but I am assuming this is what it was)

A represents 5 + 7, since he collects 5 cars and then adds 7 more the next year.

C represents 35 - 7, since he had 35 cars and then subtracted (gave away) 7 of them.

D represents 5 + 35, since he had 5 cars and then added 35 more.

Find the product (-5+3i)(-5-3i)<br> (simplify and write in form a+bi)
Anon25 [30]

Answer:

\huge\boxed{(-5+3i)(-5-3i)=34=34+0i}

Step-by-step explanation:

(-5+3i)(-5-3i)

use (a + b)(a - b) = a² - b²

=(-5)^2-(3i)^2=25-3^2i^2=25-9i^2

we know i² = -1. Therefore

=25-9(-1)=25+9=34
