Hey There,

This is a subtracting fractions problem.

Solutions-

1. Convert $5 \frac{7}{10}$ to an improper question. You do this by multiplying the denominator and the whole number and adding that number to the numerator. The improper fraction would be $\frac{50}{7}$ 

2. Now, subtract $\frac{140}{0}- \frac{15}{10}$

3. The answer to step two should be $\frac{125}{10}$

Thus, the answer should be $\frac{125}{10}=12 \frac{1}{2}$

In conclusion, Jeff drives $12\frac{1}{2}$ miles farther then her sister.

Thank You!

Write the equation for the perpendicular bisector of the given line segment.

Anon25 [30]

Answer:

$y=\frac{1}{3}x+\frac{5}{3}$

Step-by-step explanation:

Let

A(-5,5),B(-2,-4) ----> the given segment

step 1

Find the slope AB

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{-4-5}{-2+5}$

$m=\frac{-9}{3}$

$m=-3$

step 2

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

the slope of the perpendicular bisector is equal to

$m_1*m_2=-1$

we have

$m_1=-3$

substitute

$(-3)*m_2=-1$

$m_2=\frac{1}{3}$

step 3

Find the midpoint segment AB

A(-5,5),B(-2,-4)

The formula to calculate the midpoint between two points is equal to

$M(\frac{x1+x2}{2} ,\frac{y1+y2}{2})$

substitute the values

$M(\frac{-5-2}{2} ,\frac{5-4}{2})$

$M(-\frac{7}{2} ,\frac{1}{2})$

step 4

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=\frac{1}{3}$

$M(-\frac{7}{2} ,\frac{1}{2})$

substitute

$y-\frac{1}{2}=\frac{1}{3}(x+\frac{7}{2})$

step 5

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y-\frac{1}{2}=\frac{1}{3}x+\frac{7}{6}$

$y=\frac{1}{3}x+\frac{7}{6}+\frac{1}{2}$

$y=\frac{1}{3}x+\frac{10}{6}$

simplify

$y=\frac{1}{3}x+\frac{5}{3}$

I need help with this question

rosijanka [135]

(a) yes. The figures have different orientations, but that doesn't prevent them from being congruent.

(b) The 3rd selection is appropriate.

(Also the figure can be reflected across the line y = -x to get the same result.)

Compare partial products and regrouping how the methods are alike and different

melomori [17]

Partial products are different in regrouping in terms of how numbers are clustered from a set equation as a whole delivering it individual but naturally to all the numbers involved in the set.
Regrouping is just like the commutative or associative property of numbers.
Associative property of addition is used when you want to group addends. This is mainly used to cluster set of numbers or in this case, addends. How do you use the associative property when you break apart addends? Simple you group them using the open and closed parentheses or brackets. Take for an example 1 + 1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4 or 1 + (1 + 2) = 4 clustered into place.
