Lines x and y are parallel and are cut by the transversal b. If the measure of angle 1 is 57°, what is the measure of angle 6? E

lana [24]

Answer:

$\angle6=123$

Step-by-step explanation:

Given

Lines x and y

Transversal b

$\angle 1 = 57$

Required

Find $\angle 6$

From the attachment, $\angle1$ and $\angle7$ are vertically opposite.

This means that

$\angle 1 =\angle 7 = 57$

Similarly

$\angle 7$ and $\angle 6$ are supplementary angles

So:

$\angle7 + \angle6=180$

Make $\angle6$ the subject

$\angle6=180-\angle7$

$\angle6=180-57$

$\angle6=123$

The relationship between $\angle1$ and $\angle6$ is that they are supplementary angles because:

$\angle6+ \angle1=180$

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,169 was collected on the sale of 1,325 ticket

eimsori [14]

Answer:

461 adults and 864 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 1,325 tickets were purchased, then s+a=1325.

We also know that a total of $3,169 was collected and adult tickets cost $5 each and students cost $1 each. We can write 1s+5a=3169.

We will solve by substituting one equation into the other. We first solve the first equation for s which is s=1325-a. Substitute s=1325-a into 1s+5a=3169. Simplify and isolate the variable a.

1(1325-a)+5a=3169

1325-a+5a=3169

1325+4a=3169

1325-1325+4a=3169-1325

4a=1844

a=461

This means that 461 adults attended and 864 students attended since 864+461=1325.

Inequalities are used to show the relationship between unequal expressions

<em>The set notation of (5) and (6) are: </em> $\{x : -6 > x \ge -2\}$ <em> and </em> $\{x:-4 < x \ge 6\}$ <em>.</em>
<em>See attachmen</em>t for the graphs

The following should be notated when plotting the graph of an inequality

< and > are represented with open circles, while $\leq$ and $\geq$ are represented with closed circles
The arrows of and $\le$ point to the left, while the arrows of $>$ and $\geq$ point to the right.

So, we have:

$(a)\ -8 < x$

Rewrite as:

$x > -8$

The graph of $x > -8$ will point to the right, and it will use an open circle

$(b)\ -6 > x \ge -2$

Split the inequality:

$-6 > x$ and $x \ge -2$

<em>It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.</em>

<em />

Hence. $-6 > x \ge -2$ cannot be represented on a graph

$(c)\ -4$

Split the inequality:

$-4 < x$ and $x \ge 6$

$-4 < x$ means that -4 is less than x or x is greater than -4.

So, we have:

$x > -4$ and $x \ge 6$

If $x > -4$ and $x \ge 6$ , then we make use of $x > -4$ because it contains more values of x.

The graph of $x > -4$ will point to the right, and it will use an open circle
