Answer:

(-1,-8)

Step-by-step explanation:

8x + y=-16

-3x + y=-5

Multiply the second equation by -1

3x - y=5

Add this to the first equation

8x + y=-16

3x - y=5

---------------------

11x    = -11

Divide each side by 11

11x/11 = -11/11

x = -1

Now we need to find y

-3x +y = -5

-3(-1) +y = -5

3+y = -5

Subtract 3 from each side

3-3+y = -5-3

y = -8

ivanzaharov [21]

Answer: 5 inches

Step-by-step explanation:

The x's denote the insects measured so the longest insects would be of lengths:

1³/₄ inch, 1³/₄ inch and 1¹/₂ inch.

Adding them together would require converting them to improper fractions first:

7/4, 7/4, 3/2

Pick a denominator that is both denominators' lowest common multiple = 4

Adding them:

Divide the LCM by the denominator of the fraction and multiply the result by the numerator:

= (7 + 7 + 6) / 4

= 20/4

= 5 inches
