HELP QUICK!! solve by substitution and show work please

Answers

Answer:  You should solve by equal method not substitution.  y=7     x=2

Step-by-step explanation: Equal value method is when two things equal each other and in this case both 3x+1 and 5x-3 equal y so they also equal each other.   3x+1=5x-3                  add 3 to each sides

                      3x+4=5x                     subtract 3x from each side

                      4=2x                           divide by 2

                        x=2                                                             solve for y=3x+1

                                                                                                           y=3(2)+1

select all the numbers between 80 and 100 that have exactly 4 factors, one of which is 5.
80
85
90
95
100

Answers

Answer:

90.

Step-by-step explanation:

Here 5 is one of the 4 prime factors, so dividing the lower (80) and upper limit (100) by 5 we have new lower limit 16 and new upper limit 20.

So the product of other 3 factors should be greater than 16 and less than 20. And we can have it from 18 only. Hence the number is 90.

The numbers between 80 and 100 having factor 5 are

80,  85, 90, 95, 100

16 = [tex]2^{4}[/tex]

17 = 17

18 = 2× 3 × 3

19 = 19

20 = [tex]2^{2}[/tex] × 5

90 = 2 × [tex]3^{2}[/tex] × 5

Find the value of x.

Answers

Answer: x = 20

Step-by-step explanation:

The angle is 90 degrees so we can make an equation

with it.

3x + 10 + x = 90

Combine like terms

4x + 10 = 90

subtract 10 from both sides to cancel it out

4x = 80

Now divide by 4 to leave x by itself

x = 20

Now you can check if it's correct by plugging in x to the equation given

3(20) + 10

60 + 10

70

20 + 70 = 90 degrees

Answer:

D: 20 degrees

Step-by-step explanation:

First, we add 3x+10 and x together because they are within a right angle, which is 90 degrees. This gives the equation 4x+10=90. We solve from here.

We subtract 10 from both sides to isolate the x-variable. 90 minus 10 equals 80. This gives us the equation 4x=80. To further isolate the x-variable, we divide both sides by 4. 80 divided by 4 equals 20.

This leaves us with x=20.

Hope this helped!

Write 34% as a fraction or mixed number in simplest form.
The simplest form is
Basic

Answers

Answer:

17/50.

Step-by-step explanation:

In order to write 34% as a fraction or mixed number in simplest form, the following calculation has to be done:

34% = 0.34 = 34/100

34/100 = 17/50

Thus, given that 17 is a prime number that cannot be divided by other number than 1 or 17, the simplest form to write 34% as a fraction is 17/50.

What is an equation of the line that passes through the points (-6, -2) and

Answers

Answer:

y=5/6x+b

Step-by-step explanation:

use formula (y2-y1)/(x2-x1) to look for the slope:

(8-(-2))/(6-(-6))

=10/12

=5/6 (simplified)

then, use the formula y=mx+b to get the equation by substituting m and x, y to either (-6, -2) or (6, 8):

8=5/6(6)+b

8=5+b

3=b (subtract 5 on both sides)
