Answer:

7*2 and then you would go from left to right, 7*2 =14 then it would be 5+14-9, then 19-9=10 and there you go.

Solve 4−|2x−1| = −3
Vanyuwa [196]
<h3>Given</h3>

... 4 - |2x -1| = -3

<h3>Find</h3>

... x

<h3>Solution</h3>

Add |2x-1|+3

... 7 = |2x-1|

This resolves to two equations:

... -7 = 2x-1

... -6 = 2x

... -3 = x

and ...

... 7 = 2x -1

... 8 = 2x

... 4 = x

The two solutions are x = -3 and x = 4.

(Please someone help me!) (No links!)

Answer: 1 4/5 / 2/7 = 63/

10

= 6 3/10  

= 6.3

Step-by-step explanation:

Conversion a mixed number 1 4/

5

to a improper fraction: 1 4/5 = 1 4/

5

= 1 · 5 + 4/

5

= 5 + 4/

5

= 9/

5

To find a new numerator:

a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 5/

5

= 5/

5

b) Add the answer from previous step 5 to the numerator 4. New numerator is 5 + 4 = 9

c) Write a previous answer (new numerator 9) over the denominator 5.

One and four fifths is nine fifths

Divide: 9/

5

: 2/

7

= 9/

5

· 7/

2

= 9 · 7/

5 · 2

= 63/

10

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/

7

is 7/

2

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, the fraction result cannot be further simplified by canceling.

In other words - nine fifths divided by two sevenths = sixty-three tenths.

Which is true about the slope of a line?
Inessa05 [86]

Answer:

Step-by-step explanation:

The slope of all lines in quadrant 1 is positive. FALSE

The slope of a line does not depend on the quadrant.

The slope of <u>all lines</u> that pass through the origin is undefined.FALSE

The slope of some lines that pass trough the origin are undefined ( lines that are vertical have undefined slope)

The larger the slope, the longer the line.FALSE

The lines do not get longer or shorter because they go to infinity in both directions.

The larger the magnitude of the slope value, the steeper the line. TRUE

The larger the absolute value of the slope the steeper the slope.
