Answer:

C. 1/2

There are many ways to do this but I'll use substitution.

Step-by-step explanation:

Bottom equation yields x = 4 - 8y

plug that into the top equation results in:

4(4 - 8y) - y = 3y + 7

Simplify this to find y:

-36y = -9

y = 1/4

Plug that into the bottom equation we get:

x = 4 - 2 = 2

Thus, xy = 2(1/4) = 1/2 (C)

11. The table shows the lengths of fish caught by three,
blsea [12.9K]

Numbers can be ordered in ascending or descending order.

The length of fishes from greatest to least is

  • Emily = 12 \frac 34.
  • Emma = 12.7.
  • Anne = 12 \frac 35

Given

Emma = 12.7

Anne = 12 \frac 35

Emily = 12 \frac 34

Convert all fractions to decimals

Emma = 12.7

Anne = 12.6

Emily = 12.75

Arrange from greatest to least

Emily = 12.75

Emma = 12.7

Anne = 12.6

<em>Hence, the length of fishes from greatest to least is </em>

Emily = 12 \frac 34     Emma = 12.7       Anne = 12 \frac 35

The answer is C
If the two chords intersect each other, that means that they must both be diameters. That means that JL + NL has to be equal to KL + ML. Because they are both diameters, they both have to be equal to each other. The only choice that satisfies this condition is C where both of the diameters are 16 in long.

Hope this helps :)

Which expression is equivalent to 12•2•3
Ivahew [28]

Answer:

4 x 3 x 2 x 3

Step-by-step explanation:

4 x 3 = 12

12 x 2 = 24

24 x 3 = 36

It doesn't matter what order it will come out to be 36 in every situation, since PEMDAS isn't needed.
