Answer:

A

Step-by-step explanation:

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Step-by-step explanation:

Answer:

[tex]8x[/tex]

Step-by-step explanation:

[tex]x+7x[/tex]

[tex]8x[/tex]

The answer is [tex]8x[/tex] when you simplify because you are adding another [tex]x[/tex] to [tex]7x[/tex] so it becomes [tex]8x[/tex]

Answer:

It is A.

Step-by-step explanation:

100 pencils are $12, so just move the decimal 2 times to the right and there you have it.

Answer:

Triangle

base 8  

Height 6

Area 48

Rectangle

Length 16

Width 10

Area 160

48+48+160=256

Total Area of the Hexagon

256

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

b is your answer today because it is the right anawer

Answer:

I got Tuesday.

(dont count the weekends)

Answer:

Volume = 66

Surface are = 144

Step-by-step explanation:

1. Volume

The formula to find the volume of a triangular prism is the following,

[tex]A=\frac{l*w*h}{2}[/tex]

The following information is given,

lenght = 4

width = 11

hieght = 3

Substitute these numbers into the formula and solve for the heihgt,

[tex]A=\frac{l*w*h}{2}\\\\A=\frac{4*11*3}{2}\\\\A=66[/tex]

2.Surface area

The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.

The formula to find the area of a rectangle is the following,

[tex]A_r=(lenght)(width)[/tex]

The formula to find the area of a triangle is the following,

[tex]A_t=\frac{(legnth)(width)}{2}[/tex]

Substitute in the give values and add up the results to find the total surface area of the rectangle,

[tex]((5)(11))+((4)(11))+((3)(11))+(\frac{(3)(4)}{2})+(\frac{(3)(4)}{2})\\\\=55 + 44 + 33+ 6 + 6\\\\= 144[/tex]

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:

well the height of the triangle would be 5, the base is 12. The area of a triangle is the height times the base divided by 2 so 12 times 5 = 60 divided by 2= 30.

Answer:

A=30

Explanation:

b Base

12

hb Height

5

Solution

A=hbb

2=5·12

2=30

For example- 2/1 × 1/2 = 1 . Every number has a reciprocal except 0 (1/0 is undefined)

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

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

Please mark as brainlist

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:

The answer is C because how much each girl paid for each pound of cherries has the variable C attached, and the rest of the money spent added to it. Also looking in the equation the sign tells us that they paid the same price for everything totaled in all.

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:

44 miles

Step-by-step explanation:

He bikes 4 miles for every mile he runs so 11 times 4 = 44.

====================================================

Work Shown:

55% = 55/100 = 0.55

55% of 200 = 0.55*200 = 110 people prefer dogs

30% of 200 = 0.30*200 = 60 people prefer cats

Subtract the results: 110-60 = 50

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.

Step-by-step explanation:

Ok so 5 cats are in 1 row so that mean that mean there are 100 cats and in total there are 10 rows of cats so there was 5 cats on each row so the answer is 10 rows. 10 is the answer, I hope this helped!! ^^

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

Answer:

[tex]\frac{times}{days}[/tex] = [tex]\frac{20}{5}[/tex] = [tex]\frac{m}{30}[/tex]

you need to be consistant when setting up the proportions. The times always need to be on top and the days needs to always on bottom.

Cross multiply and solve for the variable.

20(30) = 5(m)

600 = 5m

120 = m

So, in 30 days the theatre showed 120 movies.
