Kim surveyed 80 students at her school and found that 0.65 of the students she surveyed said their favorite class is math. Another 15% of the students she surveyed reported that their favorite class is science. How many more students in the survey prefer math over science?



Plz Help me I don't understand-ish

[tex](2x - 9) + (3x - 6) = 110[/tex]

[tex]2x + 3x - 9 - 6 = 110[/tex]

[tex]5x - 15 = 110[/tex]

Plus sides 15

[tex]5x - 15 + 15 = 110 + 15[/tex]

[tex]5x = 125[/tex]

Divided sides by 5

[tex] \frac{5}{5}x = \frac{125}{5} \\ [/tex]

[tex]x = 25[/tex]

Thus ;

A = 2 ( 25 ) - 9°

A = 50° - 9°

A = 41°

_________________________________

B = 3 ( 25 ) - 6

B = 75° - 6°

B = 69°

_________________________________

C + 110° = 180°

because it is a straight line.

Subtract sides 110°

C + 110° - 110° = 180° - 110°

C = 70°

Answer:

1,280 cubic meters

Step-by-step explanation:

Length x Width x Height = Volume

The box on the left:

8m x 5m x 22m = 800[tex]m^{3}[/tex]

Box on the right:

12m x 5m x 8m = 480[tex]m^{3}[/tex]

Add them:

800[tex]m^{3}[/tex] + 480[tex]m^{3}[/tex] = 1,280[tex]m^{3}[/tex]

The volume of the figure is 1,280 cubic meters

Answer:

r= -3

Step-by-step explanation:

-3 r + 3(r-2) = -2(r+6)

-3r+3r-6= -2r-12

-6= -2r-12

2r=6-12

2r= -6

r= -3

Answer:

200,000 and 2005 which cant theoretically be done be P(t) which would increase in the population which would most likely be from 2005 to 2020. so you cannot do this because imagine it as X=(Y)x the mass of population which would be defined as (P) which will also be represented as a probable and physical change in the number. but not only the number, but the population. being have of the initial amount which you will take the variable (P) and have the exact amount which would be the population. Which would theoretically recon as a positive ID of the population.-Cj

Answer:

x=9

Step-by-step explanation:

First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.

You then come up with 13.5=1.5x

Divide both of them by 1.5 and then you get x=9

Answer:

X=9

Step-by-step explanation:

Okay first Hello! :)

so, B is the mid point of the segment midpoint means the half way

so, if AB= 5x+18 is the half to get the whole you would need to times it by 2

you get 10x+36

so now you equal them together

10x+36= 13x +9

Always move your smaller x, and now you got

3x+9=36

move your 9 over and switch the sign you get

3x=27

divide by three and you get

X=9

Answer: x=16

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -9/8*x-7-(-25)=0

simplify 9/8

((0 -  (9/8 • x)) -  7) -  -25  = 0

 Subtracting a whole from a fraction

Rewrite the whole as a fraction using  8  as the denominator

7 = 7/1 = 7*8/8

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

  -9x - 56  =   -1 • (9x + 56)

   Adding up the two equivalent fractions

(-9x-56) - (-25 • 8)/8     144 - 9x/8

  144 - 9x  =   -9 • (x - 16)

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, multiply both sides of the equation by the denominator.

Here's how:

 -9•(x-16)/8 • 8 = 0 • 8

Now, on the left hand side, the  8  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -9  •  (x-16)  = 0

   Solve  :    x-16 = 0  

Add  16  to both sides of the equation :  

                     x = 16

Answer: x=16
