help, again my brain is useless

Answer:

let Karen's music library be represented by K

let Clarann's music library be represented by C

C = K +18

C +K =40

put C = K +18 into (C +K =40)

K + 18 +K =40

2K +18 = 40

collect like terms

2K =40 -18

2K =22

divide both sides by 2

K =11

since C = K+18

C= 11 +18

C =29

Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

Answer:

f(12) = 185

Step-by-step explanation:

Plug 12 into every n variable of the given equation:

20 + 15(n - 1)

20 + 15(12 - 1

20 + 15(11)

20 + 165 =

f(12) = 185

Hope this helps!

Answer:

Step-by-step explanation:

Calculate f(12) if f(n) = 20 + 15(n-1) *

Answer:

A:4

Step-by-step explanation:

3/4 divided by 3/16

3/4 times 16/3

reduce

4

Answer: 4

Step-by-step explanation: do the brackets first. which is (1/2 * 3/8) to multiply these two together multiply numerator by numerator and denominator by denominator. Or, top * top / bottom * bottom

so we'd do 1*2 / 3*8. so it would give you 3/16.

now all we have left to do is divide 3/4 by 3/16.

to do this you can multiply by the reciprocal of the second value(3/16 will become 16/3)

now we have [tex]\frac{3}{4}[/tex] * [tex]\frac{16}{3}[/tex]  you can cancel out each 3 to give you 1/4 * 16/1

and you can also divide both 16 and 4 by 4 (16/4=4)

this gives you a final equation of 1 * 4 for a final answer of 4

The additional of a triangle's degree measure will always equal 180˚

When the question asks you if a triangle with 112˚, 57˚, and 11˚, you have to add them up and make sure they equal to 180˚

In this case, 112˚ + 57˚ + 11˚ DO add up to 180˚, and is indeed a triangle.

Answer: 20

Step-by-step explanation:

*This is a supplementary Angle (adds up to 180 degrees)

5x+12+68=180

5x+80=180

*subtract 80 on both sides

5x=100

*divide both sides by 5

x=20

Answer:

D) -2.14< root10 <|-2.8|

Step-by-step explanation:

the value for -2.14 is as plain as you can see, the negative version of 2.14.

The square root of 10 is 3.16227766.

The lines next to -2.8 is asking for the absolute value of -2.8, or the distance between that number and zero. The distance between -2.8 and 0 is positive 2.8, because distance can't be negative.

The 3 numbers taken from the explanations are -2.14, 3.16, and 2.8. Ranking them from least to greatest would give you -2.14, 2.8, 3.16, or -2.14< root10 <|-2.8|

Answer:

Step-by-step explanation:

c is correct.  To verify this, look at the point (4, 4) on the black graph.  For the same x value (4), we have on the red graph the point (4, 2).  If we now look at this point (4, 2) on the red graph we see that the y-value (2) is half that of the point (4, -4) on the black graph:  f(x) = (1/2)y

Answer:

m = 5 / 2

Step-by-step explanation:

Given

(4, 10)

Here,

x=4 and y=10

Given equation,

y=mx _ equation 1

putting the value of x and y in equation 1. we get,

y = mx

or, 10 = m4

or, 10 / 4 = m

or, 5 / 2 = m

therefore, m = 5 / 2
