pshichka [43]

Answer:

$6981

Step-by-step explanation:

A line passes through the point (-3, -3) and has a slope of 1/2. What is the equation of the line? A y= 1/2x + 3/2 B y= 1/2x -3/
garik1379 [7]

Answer:

(B.) y= 1/2x -3/2

Step-by-step explanation:

(-3, -3) = (x_1,y_1)\\m = 1/2\\\\y-y_1=m(x-x_1)\\\\y -(-3)=\frac{1}{2} (x -(-3)\\\\y+3 = \frac{1}{2}(x+3)\\\\ y+3 = \frac{1}{2} x+\frac{3}{2}\\\\ y = \frac{1}{2} x +\frac{3}{2} -3\\\\y = \frac{1}{2} x - \frac{3}{2}

If an average orange weighs 75 g, how many oranges would weigh 4.5 kg?​
sashaice [31]

Answer: 60 oranges

Step-by-step explanation:

<u>Given information</u>

Weight = 75 g / orange

Total = 4.5 kg

<u>Given formula</u>

Total = Number of oranges × Average weight

<u>Convert Kilogram unit to Gram</u>

1 kg = 1000 g

4.5 kg = 4.5 × 1000 = 4500 g

<u>Substitute values into the given formula</u>

Total = Number of oranges × Average weight

Number of oranges = Total / Average weight

Number of oranges = 4500 / 75

<u>Simplify by division</u>

\Large\boxed{Number~of~oranges~=~60}

Hope this helps!! :)
