Answer:

x = 5

Step-by-step explanation:

Since the base angles are congruent then the triangle is isosceles with the 2 legs being congruent, then

9x - 5 = 4x + 20 ( subtract 4x from both sides )

5x - 5 = 20 ( add 5 to both sides )

5x = 25 ( divide both sides by 5 )

x = 5

Answer:

Step-by-step explanation:

ok for this-

the equation is:

9x-5+4x+20

<u>Step 1: Combine like terms</u>

<u></u>

=9x+4x-5+20

<u>Step 2: Add the numbers: -5 + 20 = 15</u>

<u></u>

=9x+4x+15

=13x+15

<u>Step 3: Divide 13x by 13 and 15</u>

<u></u>

= \frac{13x}{13} + \frac{15}{13}

= 1.15 = x

<u></u>

The frequency table below shows the antenna careers among the incoming class of first-year college students. Every student is ch
neonofarm [45]

To solve this you must use a proportion like so...

\frac{part}{whole} = \frac{part}{whole}

The total number of students that can be chosen are 4,663. This number will represent the whole of one fraction in the proportion. We want to know what percent probability out of these students are engineer, medical doctor/surgeon. This would be considered the part of this fraction. Sum the number of engineering students (615) with medical doctors/surgeons (723) to find this number

723 + 615 = 1,338 students that want to be an engineer or medical doctor/surgeon

Percent's are always taken out of the 100. This means that the other fraction in the proportion will have 100 as the whole and x (the unknown) as the part.

Here is your proportion:

\frac{1,338}{4,663} =\frac{x}{100}

Now you must cross multiply

1,338*100 = 4,663*x

133,800 = 4,663x

To isolate x divide 4,663 to both sides

133,800/4,663 = 4,663x/4,663

28.7 = x

This means that there is a 28.7% of a student with the intent of becoming an engineer or a medical doctor/surgeon to be chosen at random

Hope this helped!

Solve these arithmetic: 2.75+0.003+0.158 =
olganol [36]
First, let's add 2.75 + 0.158.  First, we add the thousandths places.  Now, we have 2.758 + 0.15.  Next, let's add the hundredths place.  This is equal to 2.808+0.1.  Finally, we have the tenths place.  Now, our number is 2.908.

To finish this problem, we add 0.003.  2.908 + 0.003 = 2.911, so 2.911 is the answer to this problem.
