Step-by-step explanation:

Divide them up, and then after that, the parenthesis mean that you need to multiply them! So I hope that helps!

Answer:

Step-by-step explanation:

57) Order of operation: First what is inside the parenthesis - so division and then subtraction

For fraction division use KCF method

Keep the first fraction

Change division to multiplication

Flip the second fraction

[tex](\frac{5}{8}[/tex] ÷ [tex]\frac{1}{4})[/tex] - ([tex]\frac{4}{5}[/tex] ÷ [tex]\frac{1}{2})[/tex] = [tex](\frac{5}{8}*\frac{4}{1})-(\frac{4}{5}*\frac{2}{1})[/tex]

                      [tex]= (\frac{5}{2})-(\frac{8}{5})[/tex]

                      [tex]= \frac{5*5}{2*5} -\frac{8*2}{5*2}\\\\=\frac{25}{10}-\frac{16}{10}\\\\= \frac{9}{10}\\[/tex]

59)

[tex]\frac{3}{4} +\frac{1}{3} = \frac{3*3}{4*3}+\frac{1*4}{3*4}\\[/tex]

         [tex]=\frac{9}{12}+\frac{4}{12}\\\\= \frac{9+4}{12}\\\\= \frac{13}{12}[/tex]

[tex](\frac{3}{4}+\frac{1}{3})-\frac{9}{15}=\frac{13}{12}-\frac{3}{5}\\[/tex]

                    [tex]= \frac{13*5}{12*5}-\frac{3*12}{5*12}\\\\= \frac{65}{60}-\frac{48}{60}\\\\= \frac{65-48}{60}\\\\= \frac{17}{60}[/tex]

Answer:

less than

Step-by-step explanation:

4000 ft

-------------

minute

We need to convert minutes to hours and ft to miles

60 minutes = 1 hour and 5280 ft  = 1 mile

4000 ft         60 minutes       1 mile

------------- * --------------- -----  * -----------

minute         1 hour                   5280 ft

45.454545 miles / hour

Answer:

11/100

Step-by-step explanation:

11% =0,11

=11/100

[tex] \frac{11}{100} [/tex]

Answer:

1° you transform in 11/100, then you divide to get 0,11, then multiply to get 11 and this is the way you transform fraction in percentage

Answer:

1: Lowest-77 Higest: 99 Center: 88 Spread: 22

Step-by-step explanation:

Answer:

1)

Lowest: 77

Spread: 77 through 99

Highest: 99

Center: 88

2)

Lowest: 24

Spread: 24 through 84

Highest: 84

Center: 52

Step-by-step explanation:

The spread is just the numbers you are counting to so like in number 1 it is 77 through 99, does that make sense? Hope this helps!

Answer:

Ok so they had 100 cats in total so that mean each row meaning 1 row equals 5 cats so that mean's that 2, 3 or 4 didnt work.

Answer:

42%

Step-by-step explanation:

I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:

(34+8)÷100×100 = 42%

Answer:

12 balloons cause 3x4=12

Answer:

Step-by-step explanation:

Answer:

put it all together and write normally

Step-by-step explanation:

Answer:

12x + 8 = 12 x 6 + 8 = 80

8x-3 = 8 x 6 - 3 = 44

Step-by-step explanation:

(12x+8) + 55 + (8x-3) = 180 (Angle Sum Property)

(8+55-3) + (12x + 8x) = 180( group the variables)

(60) + (20x) = 180

20x = 180 - 60

20x = 120

x = 120/20 = 6

x=6

Answer:

Positive

Step-by-step explanation:

Since x > 0 =  x is positive

Since y < 0 = y is negative

Product of positive and negative number is negative.

Therefore,

       xy = - xy

    - (xy) = -( -xy)

    - (xy) = xy              [since product of negative and negative is positive]  

Answer:

429 meters

Step-by-step explanation:

half her maximum speed is 33 so multiply it by 13

Answer:

First Question = 16 Second Question = 8

Step-by-step explanation:

First one

32+48=x(2+3)

80=5x

Divide each sides with 5 and you have x=16

Second one

32+48=4(x+12)

80=4x+48

subtract 48 from 48 and 80 and you have 32=4x.

Divide it with 4 both side and you have x=8

Answer:

It is the third option.

Step-by-step explanation:

Since when making an angle of 90º an equivalence is formed between the three points and when joining them the order of the figures is given.

Answer:

12

Step-by-step explanation:

16 times 0.75 = 12

Answer:

12

Step-by-step explanation:

75%=3/4.

So, we can simplify it to 3/4 of 16

4/4 of 16 is 16.

So, 3/4 of 16 is 1/4 less than that.

1/4 of 16 is 4. We want 3/4 so we multiply 4*3=12

Hope this helps!

This line is as close as possible to all of the points. Ideally, we'd want all the points to be on the same line, but this is the next best thing.

Something like line C is close to only the left-most point, while the other points are left out. Lines A and B are a similar story to line C.

Answer:

The independent variable is the m, which is the number of minutes the hose has been running. The dependent variable is the g, which is the gallons per minute.

Answer:

g=36

Step-by-step explanation:

so if g=6m you would do 6x6 as 6 gallons per minute and g is the amount in the pool so you times them to get 35 so g=36

15 hundreds = star

Step-by-step explanation:

Move 1 thousand into hundreds place with the 5 hundreds that were already there. 5 plus 10 =15. We just don't usually think of it like that because of place value.

Answer:

I guess the answer is or the ★=2
