Answer:

Step-by-step explanation:

Given

Let the first number = x

Let the second number = 2x + 4

Let the third number = 3x -5

The sum of the three numbers = 101

Equation

x + 2x + 4 + 3x - 5 = 101 Combine like terms on the left

x + 2x + 3x + 4 - 5 = 101 Combine

6x - 1 = 101 Add 1 to both sides

6x = 101 + 1

6x = 102 Divide by 6

6x/6 = 102/6

x = 17

Answer

The first number = 17

The second number = 2*17 + 4 = 34 + 4 = 38

The Third number = 3*17 - 5 = 51 - 5 = 46

Check

17 + 38 + 46 = 101

-2/7 - (-4/3) -1/3 what is the answer

seraphim [82]

You have to first make like terms

$-\frac{2}{7} -(- \frac{4}{3})- \frac{1}{3} 
$
**you want the denominator to be 21

$\frac{-6+28-7}{21} = \frac{15}{21}= \frac{5}{7}$

Answers plz i cant do math

The slope of all parallel lines are equal.

The slope of a line in the form $y=mx+c$ is m.

1. The given equation is: $y=4x+2$ . The slope of this line is $m=4$ . The slope of the line parallel to this line is also 4.

2. The given equation is $y=\frac{2}{7}x+1$ . The slope of this line is $m=\frac{2}{7}$ .

The slope of the line parallel to it is also $\frac{2}{7}$ .

3. The next equation is $y+9x=13$ . The slope intercept form is $y=-9x+13$ .

The slope of this is $m=-13$ . The line parallel to it also has slope which is -13.

4. The given equation is $y=-\frac{1}{2}x+4$ . The slope of this line and the line parallel to it is $m=-\frac{1}{2}$

5. The equation is 6x+2y=4. We simplify to get: 3x+y=2.

The slope-intercept form is $y=-3x+2$ . The line parallel to this line has slope $m=-3$

6. Assuming the line is $y=-3x+9$ , then the slope is $m=-3$

7. Assuming the line is $-5x+5y=4$ , then the slope-intercept form is $y=x+\frac{4}{5}$ and the slope of the line parallel to this line is m=1

8. The equation is 9x-5y=4. The slope intercept form is $y=\frac{5}{9}x-\frac{4}{9}$ . The slope of the line parallel to this line is $m=\frac{5}{9}$

9. The given equation is $-x+3y=6$ . The slope intercept form is $y=\frac{1}{3}x+2$ . The line parallel to this line also has slope $m=\frac{1}{3}$ .

10. Assuming the given line is 6x-7y=10, then $y=\frac{6}{7}x-\frac{10}{7}$ and the line parallel to it has slope $m=\frac{6}{7}$

11. Assuming the line is $y-x=-3$ , then $y=x-3$ and the slope of the line parallel to it is $m=1$

12. The given line is 3x-5y=6. This implies that $y=\frac{3}{5}x-\frac{6}{5}$

How do I find the missing value

liberstina [14]

Okay. Since the "y" value and 82* are on the same straight line, their values will always add up to make a sum of 180. So if you subtract 82 from 180 you get 98*. So your "y" value is equal to 98*.

Now, all of the degree values added together should give you a sum of 360, so now we must add the values we know, in order to find the "x" value. So, 112*+82*+98*=292. Now we know that the difference of 360 and 292 will give us the x value. So finally, 360-292=68. So your "x" value is equal to 68.

y=98
x=68

find the y intercept of the line on the graph. Write your answer as a fraction or a whole number, not a mixed number or decimal.

Olin [163]

Answer:

3

Step-by-step explanation:

The answer is 3 because the blue line goes across the y - axis at 3.
