Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

<u>       -7    -7</u>

2x = 8

divide by 2 to isolate x

<u>x = 4</u>

2nd pic) y - 3 <= 6

y - 3 <= 6

<u>   +3      +3</u>

<u>y <= 9</u>

<u />

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

<u>    -0.5         -0.5</u>

x = x + 5.5

NO SOLUTION

4th pic)  5m + 10 <= 130

5m + 10 <= 130

<u>       -10        -10</u>

5m <= 120

divide by 5 to isolate the m

<u>m <= 24</u>

5th pic) 2c - 8 > 0

2c - 8 > 0

<u>      +8   +8</u>

2c > 8

divide by 2 to isolate the c

<u>c > 4</u>

An angle measures <br> 49°<br> . What is the measure of its complement?
Viktor [21]
Well if t's a right angle then the answer would be 41° but if it's an obtuse angle the it could vary from 91°-179°. For a straight angle, the answer would be 51° and for an acute angle; it could vary from 1°-89° I hope this helped ^^

<h3>Answer:   0.5</h3>

This is equivalent to the fraction 1/2

==============================================================

Explanation:

The distance from A to B is 3 units. We can count out the spaces, or subtract the x coordinates of the two points and apply absolute value.

|A-B| = |-5-(-8)| = |-5+8| = |3| = 3

or

|B-A| = |-8-(-5)| = |-8+5| = |-3| = 3

We can say that segment AB is 3 units long.

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

The distance from A' to B' is 1.5 units because...

|A'-B'| = |-2.5-(-4)| = |-2.5+4| = |1.5| = 1.5

or

|B'-A'| = |-4-(-2.5)| = |-4+2.5| = |-1.5| = 1.5

The absolute values ensure the distance is never negative.

We can say A'B' = 1.5

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

Now divide the lengths of A'B' over AB to get the scale factor k

k = (A'B')/(AB)

k = (1.5)/(3)

k = 0.5

0.5 converts to the fraction 1/2.

The smaller rectangle A'B'C'D' has side lengths that are exactly 1/2 as long compared to the side lengths of ABCD.

There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716.
solniwko [45]

x = # of balcony seats

y = # of orchestra seats

We have to create a system of equations to solve this problem

x + y = 256

$8x + $12y = $2,716

We will solve this system of equations by elimination.

Multiply the first equation by -8

-8x - 8y = -2048

8x + 12y = 2716

Let's add the equations together

0 + 4y = 668

Simplify the left side

4y = 668

Divide both sides by 4

y = 167

We can subtract 167 from 257 to get the number of balcony seats.

257 - 167 = 90 balcony seats

There are 167 orchestra seats and 90 balcony seats
