Mathematics
1 answer:
nexus9112 [7]2 years ago
6 0

Answer:

Step-by-step explanation:

2x + 3y = 2

x = 2 - 3y /2

x + y = 0

substitute the value of x

\frac{2 \\- 3y}{2} + y = 0

2 - 3y + 2y = 0

2 = y

again,substitute the value of y

x = 2 - 3y / 2

=2 - 3*2 / 2

=2 - 6 / 2

=-2

Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered t
alexgriva [62]

Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

Karina = 9 * 1\ unit^2

Karina = 9\ unit^2

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

Perry = 18 * 1\ unit^2

Perry = 18\ unit^2

Comparing both areas, we can conclude that <em>Perry's claim is correct while Karina is incorrect</em>

&lt;1 and &lt;2 are supplementary angles. The measure of &lt;1 is 87º. The measure of &lt;2 is 15x + 18º.
Kay [80]

Answer: x= 5

Step-by-step explanation: If angles 1 and 2 are supplementary, that means they add up to 180. So if angle 1 is 87, angle 2 has to be 180-87=93. Then the equation would be 15x+18=93. Subtract 18 on both sides. 15x=75. Divide by 15 and your answer is 5.

“Camilla makes and sells jewelry. She has 8,160 silver beads and 2,880 black beads to make necklaces. Each necklace will contain
Usimov [2.4K]
<h3>Answer:</h3>

96 necklaces

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

To find out how many necklaces Camilla can make, we need to see how many times the required number of beads "goes into" the available number of beads.

Silver: 8160/85 = 96

Black: 2880/30 = 96

Camilla has enough beads to make 96 necklaces.

_____

<em>Comment on this answer</em>

Obviously, if one of the quotients is smaller than the other, Camilla can only make as many necklaces as are supported by the constraining resource.

Even if she had 3000 black beads (way more than 2880), she could still only make 96 necklaces (for example) because she would run out of silver beads making that 96th necklace. (There would be 120 black beads left over in that scenario.)
