Juliana wants to find the mass of a watermelon. what unit should she use?
Anton [14]
I would recommend her to use kilograms:

grams are the standard weight unit used in the majority of the countries and in science- that's why it's better than pounds.

But kilograms are better than grams, since a watermelon weights around 2 kg, so it's easier to remember than 2000 grams.

FOR 15 POINTS I WILL GIVE BRAINLEST IF YOU ARE CORRECT! What is the solution to the system that is created by the equation y = 2
goblinko [34]

The solution point is (4,2).

Step-by-step explanation:

Equation of straight line passing through the points (0,0) and (4,2) is given by

⇒ 2y = x ............ (1)

And the other straight line is y = - x + 6 .............. (2)

Now, solving equations (1) and (2) we get, y = - 2y + 6

⇒ 3y = 6

⇒ y = 2

And from equation (1) we get, x = 2y = 4

Therefore, the solution point is (4,2). (Answer)

Golf balls can be purchased in a 3-pack for $4.95 or a 12-pack for $18.95. Which is the better buy? Which Item cost less per gol
natka813 [3]
I think the better buy would be the 12-pack because the quality of the ball and the brand would determine the price. Golf balls do the same thing, you hit than lose it than buy a whole new pack of balls. The 3-pack cost less because it’s $4.95 and the 12-pack cost $18.95. By $14 much.

Given segment AC and point B that lies on AC,
ololo11 [35]

The total length of the segment AC is the sum of AB and CB, which gives, CB = 9

<h3>How can the length of CB be found?</h3>

The given parameters are;

  • AC = 17
  • AB = 32 + 3•x
  • CB = 57 + 6•x

Required: <em>CB</em>

Solution:

AC = <em>AB + CB</em> by segment addition property

Therefore;

AC = 17 = 32 + 3•x + 57 + 6•x = 89 + 9•x

17 = 89 + 9•x

x =  \frac{17 - 89}{9}  =  - 8

CB = 57 + 6•x = 57 + 6 × (-8) = 9

Therefore;

  • <u>CB = 9</u>
