Answer:

\frac{7}{-6}

Step-by-step explanation:

To do this you are basically dividing the fractions so when you set up the equation it will look like this \frac{1}{2}/\frac{-3}{7} now that we have this we will take the reciprocal of -3/7 which is 7/-3 and than multiply the 2 fractions we we get 7/-6

Find X, and the two angle measures.
Snowcat [4.5K]

Answer:

x = -4

m<LMP = 77°

m<NMP = 103°

Step-by-step explanation:

Straight angles by definition have a total measure of 180°.

This means that m<LMP and m<NMP are 180° together.

Therefore m<LMP + m<NMP = 180°.

[substitution property]

(-16x + 13)° + (-20x + 23)° = 180°

[associative property of addition]

(-36x + 36)° = 180°

-36x + 36 = 180

–36 –36

-36x = 144

÷-36 ÷-36

x = -4

_________________

Since m<LMP = (-16x + 13)°.

Using substitution with x = -4:

m<LMP = (-16(-4) + 13)° = (64 + 13)° = 77°.

Since m<NMP = (-20x + 23)°.

Using substitution with x = -4:

m<NMP = (-20(-4) + 23)° = (80 + 23)° = 103°.

This is true because 77° + 103° = 180°.

In the park, Bryce hikes 4 1/2 mi and Jessie hikes 6 7/16 mi. How much farther does Jessie hike than Bryce? Express your answer
soldier1979 [14.2K]

is simply the difference of both amounts, but firstly let's convert the mixed fractions to improper, and subtract.


\bf \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}}&#10;\\\\\\&#10;\stackrel{mixed}{6\frac{7}{16}}\implies \cfrac{6\cdot 16+7}{16}\implies \stackrel{improper}{\cfrac{103}{16}}&#10;\\\\[-0.35em]&#10;\rule{34em}{0.25pt}\\\\&#10;\stackrel{Jessie}{\cfrac{103}{16}}-\stackrel{Bryce}{\cfrac{9}{2}}\implies \stackrel{\textit{our LCD is 16}}{\cfrac{(1)103-(8)9}{16}}\implies \cfrac{103-72}{16}\implies \cfrac{31}{16}\implies 1\frac{15}{16}

HELP FAST WILL MARK BRAINLEIST
ValentinkaMS [17]

Step-by-step explanation:

The given inequality is

10 + 5x \leqslant 35

Subtract 10 from both sides

5x \leqslant 35 - 10

5x \leqslant 25

Divide both sides by 5 to get:

x \leqslant 5

We draw a closed circle at 5 and draw the arrow to the left.

See it in the attachment.
