Answer:

-6 < x [tex]\leq[/tex] 6

Step-by-step explanation:

-5 < [tex]\frac{x-4}{2}[/tex] [tex]\leq[/tex] 1

Multiply all the sides by 2

-10 < x-4 [tex]\leq[/tex] 2

Add 4 to all the sides

-6 < x [tex]\leq[/tex] 6

Answer:

-6 < x < 6

Step-by-step explanation:

either way its still higher than -5 and lower than 1

Answer:

1, 1, 17

Step-by-step explanation:

17 is a prime number. This means the only factors are 1, and 17. This means that since only 17, and 1 multiply to 17, to get a volume of 17 you can only use 1, and 17 (1, 1, and 17)

Answer:

His brother gets 8 apples

His friends gets 4 apples

He gets 12 apples

Step-by-step explanation:

brother: friend himself::total

2                1          3        2+1+3 = 6

He has a total of 24 apples

24/6 = 4

Multiply each term by 4

brother: friend himself::total

2*4           1*4        3*4        6*4

8                4          12           24

His brother gets 8 apples

His friends gets 4 apples

He gets 12 apples

Answer:

0.6 OR 0.60

Step-by-step explanation

A trick to use is that always put the zero first. For example 50/100 would equal 0.50 because of those 3 digits.

Answer:

0.6

Step-by-step explanation:

Answer:

Therefore the least common denominator is 24.

Step-by-step explanation:

2/6 = 8/24

7/8 = 21/24

No more explanation.

Answer:

24

Step-by-step explanation:

Both denominators 6 & 8 have a LCM of 24

Therefore the least common denominator is...

Step-by-step explanation:

Let x, and x+1 be the consecutive numbers.

[tex]x + (x + 1) = 37[/tex]

[tex]2x + 1 = 37[/tex]

[tex]2x = 36[/tex]

[tex]x = 18[/tex]

Plug in 18 for x+1,

[tex]18 + 1 = 19[/tex]

So the numbers is 18,19

Answer:

18 and 19

Step-by-step explanation:

if you have two consecutive numbers, then using algebra, one unknown number is x and the other unknown consecutive number is x + 1

The equation x + x + 1 = 37

To solve this equation subtract 1 from both sides as one does in algebra.

x + x + 1 = 37 → x + x + 1 - 1 = 37 - 1

Now you have the equation x + x = 36

This can rewrite this as 2x = 36        2x means 2 times the value of x

To solve this part of the equation divide both sides by 2

2x / 2 = 36 / 2

x = 18

The next consecutive number x + 1 = 19, (18) + 1 = 19

check this by adding. 18 + 19 = 37.

Answer:

a. true

b. false

c. false

d. false

e. true

Step-by-step explanation:

a is true because the graph is measuring the weight of the box based on the number of cookies in it, and the box has weight even without cookies in it.

b is false because the slope of the line is 1/2, and each cookie weighs 1/4 oz.

c is false because there is an association between the number of cookies and the weight of the box.

d is false because that is the weight of one cookie, and doesn't take into account the weight of the box by itself.

e is true because the graph shows that at 13 cookies, the box weighs around 3.75 ounces.

Answer:

x = -8/3 and y = -49/3

Step-by-step explanation:

(Step 1) To solve using substitution, you first need to isolate a variable in one of these equations. I chose to isolate "y" in the following equation.

-8x + y = 5                                        <--- Original equation

y = 5 + 8x                                         <--- Add 8x to both sides

(Step 2) Now, substitute (5 + 8x) for "y" in the second equation.

5x - y = 3                                          <--- Original equation

5x - (5 + 8x) = 3                               <--- Substitute 5 + 8x for "y"

5x - 5 - 8x = 3                                  <--- Distribute (-) in the parentheses

-3x - 5 = 3                                        <--- Combine terms with "x"

-3x = 8                                              <--- Add 5 to both sides

x = -8/3                                             <--- Divide both sides by -3

(Step 3) Since you know the value of "x", plug it into one of the equations to solve for "y".

y = 5 + 8x                                         <--- Original (rearranged) equation

y = 5 + 8(-8/3)                                   <--- Plug (-8/3) for "x"

y = 5 - 64/3                                       <--- Multiply

y = 15/3 - 64/3                                   <--- Convert 5 into a fraction

y = -49/3                                           <--- Subtract

(Step 3.5) You can check your work by plugging "y" into the other equation to see if the answer for "x" is the same.

5x - y = 3                                             <--- Original equation

5(-8/3) - y = 3                                      <--- Plug (-8/3) for "x"

-40/3 - y = 3                                        <--- Multiply

-40/3 - y = 9/3                                     <--- Convert 3 into a fraction

-49/3 - y = 0                                        <--- Subtract both sides by 9/3

-49/3 = y                                             <--- Add both sides by "y"

The value of the system of equations is x = -8/3 and y = -49/3.

Answer:

A.) 15984.42cm^2/5088πcm^3

B.) 3466.56cm^2/1104πcm^2

Step-by-step explanation:

A.) fine the V of the cone and then cylinder then add them.

B.) The cone you have to find the LA (lateral area) to do that you would do is find S (slant) so you would do 12^2+16^2 which is 400 then u have to find the square root of it which is 20 which is that slant of the cone. After that you would do 12x20 which gives 240 that would be the LA of the cone.

Then you would find the LA of the cylinder which you have to do is 30x12 which is 360 then multiply it by 2 which gives 720.

Lastly you find the area of the base which in this case is a circle and that would be 144 add all of them then get the SA
