Let n represent the number. You require
   7n - 2n = 55
   5n = 55 . . . . . . collect terms
   n = 11 . . . . . . . divide by 5

The number is 11.

Find the measures of the interior angles of the triangle.
Maurinko [17]

Answer:

A=45

B=110

Step-by-step explanation:

Interior angles of a triangle add up to 180.

So, do 180-25=155.

Then, 155-65=90.

90 divided by 2 is 45.

x=45 so B is 45+65, which is 110.

What are the intercepts of y=4x-2
Lemur [1.5K]
Answer:

To find the x-intercept, make y equal to zero, and solve for x. To find the y-intercept, make x equal to zero, and solve for y.

Explanation:

<span>y=4x−2</span>

<span>
</span>

X-Intercept


<span>0=4x−2</span>

<span>
</span>

Add 2 to both sides of the equation.


<span>2=4x</span>

<span>
</span>

Divide both sides by 4.


<span><span>2/4</span>=x</span>

<span>
</span>

Simplify.


<span><span>1/2</span>=x</span>

<span>
</span>

Switch sides.


<span>x=<span>1/2</span></span>

<span><span>
</span></span>

Y-Intercept


<span>y=4<span>(0)</span>−2</span>

<span>y=−2</span>

HELP PLEASE and show work
larisa86 [58]

Answer:

\boxed{\stackrel{\Large\frown}{PQS}\:= 222°}

Explanation:

Since \overline{PR} is a diameter, arc \stackrel{\Large\frown}{PQR}\:= 180°.

Given that \angle{SUR} = 42° is a subtended central angle by two diameters,

\stackrel{\large\frown}{RS} \:= 42°.

Using the rule of arcs, \stackrel{\Large\frown}{PQR} + \stackrel{\large\frown}{RS} \: = \: \stackrel{\Large\frown}{PQS} →

180° + \: 42° = \: \stackrel{\Large\frown}{PQS}

222° = \: \stackrel{\Large\frown}{PQS}

\stackrel{\Large\frown}{PQS} \: = \: 222°
