Answer:

y =x-12

Step-by-step explanation:

$(x_1, y_1) = (16, 4) \ \ \ and \ \ \ (x_2, y_2) = (17, 5)$

Equation of straight line is

$y-y_1 =\frac{y_2-y_1}{x_2-x_1} (x-x_1)$

$y-4 =\frac{5-4}{17-16} (x-16)$

$y =(x-16)+4$

$y =x-12$

Mason loves collecting sea glass from the beach. He recorded the weight of each jar full of sea glass. If he decided to distribu

lara31 [8.8K]

<em>The missing weights are:</em>

Answer:

$Average = 12\frac{4}{7} \ lb$

Step-by-step explanation:

Given

Weight of sea glass

To solve this question, we have to calculate the mean of the weight of the sea glass as follows;

$Average = \frac{\sum x}{n}$

Where n = number of sea glass

$n = 14$

So:

$Average = \frac{\sum x}{n}$ becomes

$Average = \frac{2 +2 + 2 + 1 + 11 +12 +12 +2 +24+22 +24 +3 +37+ 22}{14}$

$Average = \frac{176}{14}$

$Average = 12\frac{8}{14}$

Simplify fraction

$Average = 12\frac{4}{7}$

<em>Hence; the weight of the sea glass would be </em> $12\frac{4}{7}\ lb$ <em> </em><em>when evenly distributed...</em>

Solving for y what is 3x-4y=-8<br> solving for y what is 3x-4y=-8

Sati [7]

Answer:

y=2+0.75x

Step-by-step explanation:

3x-4y=-8

first, subtract 3x from both sides

-4y=-8-3x

Alex, Bob, and Claudia split 126 cm wire evenly among themselves. They then proceeded to cut their pieces of wire into smaller,

Westkost [7]

<h3>Answer:</h3>

Bob
18 cm

<h3>Step-by-step explanation:</h3>

If Alex cut his wire 18 times, he ended up with 19 equal pieces. He kept 7, so has 7/19 of his 1/3 of the wire.

Bob cut his wire 20 times, so ended up with 21 pieces, of which he kept 9. So he has 9/21 = 3/7 of his 1/3 of the wire.

Claudia kept 1/13 of her 1/3 of the wire, so has the smallest piece.

Bob kept (3/7)·(1/3)·126 cm = 18 cm.

Alex kept (7/19)·(1/3)·126 cm ≈ 15.47 cm.

Bob kept the longest part of the original wire.
