Answer:

A triangle has to equal 180 degrees.

Brrunno [24]3 years ago

Answer:

90

Step-by-step explanation:

All three angles of any type of triangle should add up to 180 degrees

So if x (the degree of one angle)plus x+65(the degree of the other angle) plus 25(the degree for the third angle) equals 180, the equation should look like this

x+(x+65)+25=180

2x+65+25=180

2x+90=180

2x=90

x=45

So x equals 45, but we are not done yet

The question says to define x+65, so

x+65

45+65

110

110 is the answer

Answer:

3.5p ≤ 40

Step-by-step explanation:

The inequality that best describes this problem is 3.5p ≤ 40;

Given parameters:

Total amount with me = $40

Cost per package of hot dog  = $3.5

Unknown;

The inequality that represents the problem  = ?

Solution:

p is the number of hotdogs that can be bought.

  So, total hotdog that can be bought if each hotdog cost $3.5 per box is;

                    p x 3.5

Now,

    this will equal the total amount at hand;

       p x 3.5 ≤ 40

         3.5p ≤ 40

Please help me with the problem below! :)
Drupady [299]
First, lets subtract the goal by 3, because she already did them.

15 - 3
12

Now, lets divide by one because that will leave you with the number of days

12/1
12

So, It will take her 12 days if she keeps up with her goal.

Hope this helps!

Write the following quotient in the form a+bi.<br> -7i/2-7i
Helga [31]

Answer:

\large\boxed{\dfrac{49}{53}-\dfrac{14}{53}i}

Step-by-step explanation:

\text{Use}\\\\i=\sqrt{-1}\to i^2=-1\\\\(a-b)(a+b)=a^2-b^2\to(a-bi)(a+bi)=a^2+b^2\\\\\text{distributive property}\ a(b+c)=ab+ac\\---------------------\\\\\dfrac{-7i}{2-7i}=\dfrac{-7i}{2-7i}\cdot\dfrac{2+7i}{2+7i}=\dfrac{-7i(2+7i)}{2^2+7^2}=\dfrac{(-7i)(2)+(-7i)(7i)}{4+49}\\\\=\dfrac{-14i-49i^2}{53}=\dfrac{-14i-49(-1)}{53}=\dfrac{-14i+49}{53}\\\\=\dfrac{49}{53}-\dfrac{14}{53}i
