Use three unit multipliers to convert 1520metes to yards

1. 4560 ft.

2. 9

3. 2 × 2 × 3 × 5 × 7

4. 3

5. f(-2) = 9

6. - 9, - 9

7.

Step-by-step explanation:

1. We have to convert 1520 meters to feet using 3 as a unit multiplier.

So, 1520 m = (1520 × 3) ft = 4560 ft. (Answer)

2. Assume the number is x, then the opposite number is - x.

So, given that -2x + 27 = x

⇒ 3x = 27  

⇒ x = 9 (Answer)

3. 420 = 2 × 2 × 3 × 5 × 7 (Answer) {Using factorization method.}

4. 2 is  of 3. Since, . (Answer)

5. if f(x) = - 5 - 7x, then f(-2) = - 5 - 7(- 2) = - 5 + 14 = 9 (Answer)

6.a)  and

b)  (Answer)

7. We have to factor the greatest common factor of

. (Answer)
