Determine the common factor and HCF for each of the following terms.

1)8y,12y
2)2b,3b
3)3w,5w²​

Answers

Answer:

Step-by-step explanation:

1) 8y = 2 * 2 * 2 * y

 12y = 2 * 2 * 3 * y

Common factors = 2 , 2 , y

HCF = 2*2y = 4y.

2) 2 b = 2 *b

 3b = 3 * b

Common factor = b

HCF = b

3) 3w = 3 *w

5w² = 5 * w * w

Common factor = w

HCF = w

-3x + -15 = 12
x = __

Answers

Answer:

x=9

Step-by-step explanation:

alright so first we eliminate the -15 and to do that we add 15 on both sides:

-3x-15+15=12+15

-3x=27

Now we divide 3 on both sides to make the equation equal to x

[tex] \frac{-3x}{-3} = \frac{27}{-3} [/tex]

x=9

And that's your answer, you're welcome :)

A shopping mall has a moving sidewalk that takes shoppers from the shopping area to the parking garage, a distance of 220 ft. If your normal walking rate is 5 ft/s and the moving sidewalk is traveling at 3 ft/s, how many seconds would it take for you to walk from one end of the moving sidewalk to the other end?

Answers

So you’d add 5 and 3 so it’s 8 ft/s

You then divide 220/8

So it should be 27.5 seconds.

Answer:

To solve, multiply by the reciprocal of the coefficient of m. Because that is negative, the inequality symbol must be reversed.
