Answer:

A. \frac{9}{5}

Step-by-step explanation:

-\frac{1}{4} ( -\frac{4}{5} / \frac{2}{3} ) 6

Note that when dividing fractions, you can flip one and multiply instead to gte the same answer.

-\frac{1}{4}*6( -\frac{4}{5} * \frac{3}{2} )

\frac{-6}{4} ( \frac{-4*3}{5*2} )

\frac{-6}{4} ( \frac{-12}{10} )

\frac{-6*-12}{4*10}

\frac{72}{40}

Divide top and bottom by 8.

\frac{72/8}{40/8}

\frac{9}{5}

Given f(x) =x-7 and g(x) =x2 find g(f(4))
8090 [49]

Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7            [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)²      [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.

Brian is 1 meter 87 centimeters tall. Bonnie is 58 centimeters shorter than Brian. Betina is 26 centimeters taller than Bonnie.
Blizzard [7]

Answer:

Betina is 1\ m\ 55\ cm tall

Step-by-step explanation:

let

x ----> Brian's height

y ----> Bonnie's height

z ----> Betina's height

we know that

1\ m =100\ cm

1\ m\ 87\ cm=100\ cm+87\ cm=187\ cm

so

x=187\ cm

y=x-58

substitute the value of x

y=187-58=129\ cm

z=y+26

substitute the value of y

z=129+26=155\ cm

155\ cm=100\ cm+55\ cm=1\ m\ 55\ cm

therefore

Betina is 1\ m\ 55\ cm tall

Please Help Fast!! 15 Point and brainiest if correct
iragen [17]

If a < b, then dividing both sides by a positive number will not flip the inequality sign. The inequality flips if you divide both sides by a negative number.

So if a < b, then a/3 < b/3 as well.

<h3>Answer: Less than sign (first choice)</h3>

Kyle says the number is greater when an object is measured in centimeters than in millimeters. Is Kyle correct? Explain
Lerok [7]
False.

1 centimeter = 10 millimeters.

with this knowledge, we can say, for example, that:

70 (in millimeters) as a number is greater than 7 (in centimeter), as 70 > 7


hope this helps
