8 0

Answer:

-54y+63

Step-by-step explanation:

9\{[4(y-4)+18]-[2(5y-2)-1]\}

Simplifying the innermost parenthesis by distribution and simplifying.

9\{[4y-16+18]-[10y-4-1]\}

9\{[4y+2]-[10y-5]\}

Now, reversing the signs of the terms inside brackets coming after negative sign to remove the brackets.

9\{4y+2-10y+5\}

Combining like terms

9\{-6y+7\}

Using distribution to remove the braces.

-54y+63

Points A, B, and C are collinear, and B lies
olya-2409 [2.1K]

Answer:

BC = 30

Step-by-step explanation:

If the three points are collinear, it means they lie on the same straight line.

Now B lies between A and C

By mathematical convention;

AC = AB + BC

This means;

48 = 2x + 2 + 3x + 6

48 = 5x + 8

48-8 = 5x

5x = 40

x = 40/5

x = 8

From the question BC = 3x + 6

Substitute the value of x; 3(8) + 6 = 24 + 6 = 30

how many legs do 10 people have? if two people dont have legs. one person has 3 legs and one person has one leg. and mary has a
Ganezh [65]
So here is the answer. Normally, 10 people have 20 legs since each person has 2 legs each. But given the scenario that two people don't have legs, this would mean 20 minus 4, is 16 legs. Then one person has 3 legs, 16 plus 3 and it is 19. And then, another person has one leg, 19 plus 1 is 20. Therefore, the total legs would still be 20. Hope this helps. The dog does not count.
