Well.. There's 3y-2=y+4 right?
Add 2 and you get 3y=y+6
Minus y- you get 2y=6
Divide it at 2 and you get y=3.
Sorry for the explanation but I'm from another country and this is the best I can

From his house, Manuel could drive due north to get to his parents' house or he could drive due east to get to his grandparents'
maxonik [38]

Answer:

The distance is 8 miles.

Step-by-step explanation:

Manuel's house, his parents house, and grandparents house can be expressed as the three vertices of a right angled triangle. Thus, Pythagoras theorem can be applied to determine the distance from Manual's house to that of his grandparents.

Let the distance from Manuel's house to that of his grandparents be represented by x, so that;

/Hyp/^{2} = /Adj 1/^{2} + /Adj 2/^{2}

/10/^{2} = /x/^{2} + /6/^{2}

100 = x^{2} + 36

x^{2} = 100 - 36

   = 64

⇒ x = \sqrt{64}

      = 8

x = 8 miles

Thus, Manuel's house is 8 miles from his grandparents house.

Hello everyone can you answer this for me? What is A in the equation attached? Please and thank you.
lapo4ka [179]

Answer:

a = 6

Step-by-step explanation:

Hello!

Solve:

  • 4(3a - 4) = 56
  • 3a - 4 = 14          (factoring out 4)
  • 3a = 18               (adding 4 to both sides)
  • a = 6                   (dividing by 3)

Another way:

  • 4(3a - 4) = 56
  • 12a - 16 = 56        (distributive property)
  • 12a = 72               (moving like terms)
  • a = 6                    (dividing by 12)

Distributive Property of Multiplication:

The process of distributing the outside factor to the terms in the parenthesis.

Example:

4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16
