the answer is 0.25,0.5,1,2,2

Answer:

x = -1

Step-by-step explanation:

use the value of y and plug it in

2 = 2x + 4

-4. -4

-2 = 2x

divide each side by 2

-1 = x

you can plug it back in to see if it is right

Answer:

y=2x+4       y=2

2=2x+4

-4      -4

2x= -2

----   ----

2      2

x = -4

Step-by-step explanation:

CHECK:

step 1: Plug everything in.

2=2 correct   y=2x+4

                     2=2(-4)+4

                    2= -8+4

                    2= -4

                   divide 4 by 2

                     2= -2 correct      pls mark as brainliest!

Step-by-step explanation:

-48/192=-1/4

Answer:

-12

Step-by-step explanation:

Let x be "the number."  

"Three times a number" means 3x

"is 24 less than the number" means = x-24

Put them togehter:

3x = x-24

2x = -24

x = -12

Check:  Is 3(-12) = 24 less than -12?  YES.

If factors are only rounded up, then the estimate is an overestimate. If factors are only rounded down, then the estimate is an underestimate. If factors are rounded up and down, it is more difficult to determine whether the estimate is an overestimate or an underestimate.

Answer:

Theater: Comedy 61% Drama 39% Home: Comedy 60% Drama 40%

Step-by-step explanation:

Theater: first add 57 and 36 to get the total amount, then do comedy/total, which is 57/93, when you divide this it equals 0.612. Multiply this by 100 and you get 61.2 %, repeat this formula for the rest: x or y/x+y x being one amount and y another amount. x+y is just the total amount. *If you don't care about how to do it look below*

Theater:

Comedy: 57/93 x 100=61%

Drama: 36/93 x 100=39%

Home:

Comedy: 78/131 x 100=60%

Drama: 53/131 x 100=40%

The numbers of new CDs is 30 and the old CDs is 21.

To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.

This is used to solve a series or complex of word problems in which we can represent in a mathematical statements;

The equations can be represented as

[tex]n + u = 51 ...equation(i)\\15n + 6u = 576 ... equation(ii)[/tex]

Let's take equation (i)

Making n the subject of formula

[tex]n + u = 51\\n = 51 - u...equation(iii)[/tex]

we can put equation (iii) into equation (ii)

[tex]15n + 6u =576\\n = 51 - u\\15(51 - u) + 6u = 576\\765-15u + 6u = 576\\collect like terms\\765-576=15u - 6u\\189=9u\\9u/9 = 189/9\\u = 21[/tex]

Let's put the value of u into equation (i)

[tex]n + u = 51\\u = 21\\n + 21 = 51\\n = 51 - 21\\n = 30[/tex]

From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.

Triangular prism has 4 sides, including the base. The lateral area of the considered triangular prism is given by option B: [tex]12x^2 \: \rm inch^2[/tex]

Lateral area of the considered triangular prism is the sum of areas of the triangles it is made up from except that of the base triangle.

The lateral area of a right prism which is regular (all lateral sides congruent) is given by:

[tex]A_L = P \times h[/tex]

where, P = Perimeter of the base

h = height of that prism

For the given case, we have the base of the triangular prism of side length x units.

Thus, perimeter of the base = x + x + x = 3x

Height of the base = h = 4 times x = 4x

Thus, we get:

Lateral area of the prism = [tex]3x \times 4x = 12x^2 \: \rm inch^2[/tex]

Thus, The lateral area of the considered triangular prism is given by option B: [tex]12x^2 \: \rm inch^2[/tex]

Answer:

the answer to the first one is 118 the value of x is 113

Step-by-step explanation:

SOMEONE DELETED MY ORIGINAL ANSWER

The two angles will be linear pairs if the sum is 180° therefore,linear pair of 62° is 118° so option [A] is correct.

The value of x in the figure is 113° so option [C] is correct.

The m∠EXD and m∠AXE are the supplementary angles so option (B) is correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

01)

Two angles will be linear pairs if their sum is 180°.

If the first angle is 62° then the second will be 180° - 62° = 118°

Hence "The two angles will be linear pairs if the sum is 180° therefore, linear pair of 62° is 118°".

02)

The angle x is in the same line with supplementary angle 67° so

x = 180 - 67 = 113°.

Hence "The value of x in the figure is 113°".

03)

In the figure, AXD is a straight line, therefore,

m∠EXD +  m∠AXE  = 180°

Since the sum of two angles is 180° then they are called supplementary angles.

Hence "The m∠EXD and m∠AXE are the supplementary angles".

Answer:

240 m

Step-by-step explanation:

Figure is attached.

The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min.  The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).

What's the area under the graph?

The red outline forms a trapezoid.  The area of a trapezoid is  [tex]A=\frac{1}{2}h(b_1+b_2)[/tex]  where the b's are the lengths of the two parallel base and  h  is the height (the distance between the bases).

Reading the graph carefully (notice the scales!)...

Calculate distances

Opposite sides are equal so it's rectangle

Answer:

5572.45

Step-by-step explanation:

the formula to calculate the colume of a sphere is (4/3)πr², where r is the radius of the sphere.

to find r (radius):

- divide the diameter by 2 because d = 2r, where d is the diameter and r is the radius

r = 22/2

= 11 in

to find volume of the globe:

- substitute r = 11 into (4/3)πr³

v = (4/3)π(11)³

= 5324π/3

≈ 5575.27976 in³

hence, the best approximation of the globe is 5572.45 in³.

Answer:

tn=a+(n-1)d
