Answer:

1. x= 9/2

2. x= -5/11

Step-by-step explanation:

1. -1-3x+7x=17

=> -3x+7x= 17+1

=> 4x= 18

=> x= 18/4

=> x=9/2

2. 4x-5+7x=-10

=> 11x= -10+5

=> 11x= -5

=> x= -5/11

Step-by-step explanation:

1. -3x+7x=18

    x(-3+7)=18

      x=\frac{18}{(-3+7)}

2. 4x+7x=-5

    x(4+7)=-5

     x=\frac{-5}{(4+7)}

I hope this helped, may be wrong but ive done it my way

two numbers have these properties both numbers are greater than 8 their highest common factor is 8 their lowest common multiple
arsen [322]

Answer: 8 and 80

Step-by-step explanation:

8 * 5 = 40

8 * 10 = 80

8 must be the hcf of two separate numbers. So, one of them must be 8, and the other must be greater than 8.

Multiples of 8:

8

16

24

32

40

48

56

64

72

80

The numbers on that list that multiply evenly to 80:

8, 16, 40, 80

16 is the lowest common multiple of 16 and 8

40 is the lowest common multiple of 40 and 8

80 is the lowest common multiple of 80 and 8

So the two numbers are 8 and 80; the highest common factor (HCF) is indeed 8.
