10c+20c=40
or, 30c=40
or, c=40/30
Answer:
C= 2
Step-by-step explanation:
An advertising agency increased their fees to an $80 setup fee plus $4 for every advertisement. Write a rule for the new fee. Write ordered pairs for the fees for 10, 20, 30, and 40 advertisements.
a. y = 80 + 4 + x
(120, 10), (160, 20), (200, 30), (240, 40)
b. y = 80 + 4x
(10, 120), (20, 160), (30, 200), (40, 240)
c. y = 80 + 4x
(120, 10), (160, 20), (200, 30), (240, 40)
d. y = 80 + 4 + x
(10, 120), (20, 160), (30, 200), (40, 240)
please help !!!!
Answer:
b.
Step-by-step explanation:
As it says there is already a set up fee of $80 and it is $4 FOR EVERY advertisement, the equation would be y = 80 + 4x. Obviously, y should be greater than x since you are calculating the cost and not anything else, so b should be your answer. Even without logically guessing, the equation proves that b is correct.

Johnny's home is m miles from school. Johnny runs to school at a speed of 8 mph and then walks home from school at half that speed. Suppose it take johnny 15 longer to walk to home than to run to school. Write an equation that shows this relationship.
Answer:
first we know the speed from home to school is 8mph and from school to home is half that speed so 4 miles per hour
now,
from home to school it takes: m/8 hours
and from school to home m/4 hours
we can pass it to minutes multiplying by 60
so:
from home to school it takes: m*7.5 minutes
and from school to home m*15 minutes
and now the relations between these two amount of minutes is that takes 15 more from school to home so:
7.5m+17

Which values of k are solutions to the inequality?
k>12
Select each correct answer.
k = 11.9
k = 12.1
k = 13.0
k = 19.9
k = 10.2Which values of k are solutions to the inequality?
k>12
Select each correct answer.
k = 11.9
k = 12.1
k = 13.0
k = 19.9
k = 10.2
Answer: B. k = 12.1.
C. k = 13.0.
D. k = 19.9.
Step-by-step explanation: Which values of k are solutions to the inequality k>12 are B. k = 12.1 , C. k = 13.0 , and D. k = 19.9 because it literally says k>12 so every value of k that's solutions to the inequality k>12 have to be greater than 12. Due to this B. k = 12.1, C. k = 13.0, and D. k = 19.9 are the correct answer choices that you should choose and the incorrect answer choices that you shouldn't choose are A. k = 11.9, and E. k = 10.2 .
Answer:k + 13.0

What is the value of the expression 5(6/12-1/4) + 0.5
Answer:
5/8
Step-by-step explanation:
First you need to reduce the fractions then you choose a common denominator to calculate:6/12=1/2 then you see the you see 1/4 can be a common denominator so you equal 1/2 to the denominator by 4, which means multiplying 2 by both the numerator and denominator, we get 2/4 after that you add and subtract in parentheses and you will get 1/4 then you multiply by 5 to get 5/4 the finally you have to plus 0,5 you will get 7/4 done.

Answer: y = -3x - 6
Step-by-step explanation:
One way to write a linear equation is with slope-intercept form. Slope-intercept form is y = mx + b, where m is the slope, and b is the y-intercept.
Thus, the equation is y = -3x - 6
Hope it helps :) and let me know if you are confused anywhere.
Answer:
y = -3x - 6
Step-by-step explanation:
Insert the information into the slope-intercept form equation:
y = mx + b
m = slopeb = y-intercept valueIn this instance, the slope is -3 and the y-intercept value is -6. Therefore, the equation of the line is y = -3x - 6

tax+original price = total amount paid
4+40=44
what is the slop of the line that passes through the points (-2,3) and (-14,-5)? write your answer in simplest form.
Answer:
2 / 3
Step-by-step explanation:
( x1, y1 ) = ( - 2, 3 )
Here,
x1 = - 2
y1 = 3
( x2, y2 ) = ( - 14, - 5 )
Here,
x2 = - 14
y2 = - 5
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( - 5 - 3 ) / ( - 14 - ( - 2 ) )
= - 8 / ( - 14 + 2 )
= - 8 / - 12
Slope = 2 / 3

Safe Combination. The author owns a safe in which he stores all of his great ideas for the
next edition of this book. The safe combination consists of four numbers between 0 and 99. If
another author breaks in and tries to steal these ideas, what is the probability that he or she will
get the correct combination on the first attempt? Assume that the numbers are randomly
selected. Given the number of possibilities, does it seem feasible to try opening the safe by
making random guesses for the combination?
Answer: 1/96059601
Don't break in
Step-by-step explanation:
First we need to find how many combinations there are.
We can find that by multiplying the four different number of options which in this case are all 99.
99 * 99 * 99 * 99
= 96059601
There are 96059601 different combinations and one correct combination.
So, the chance of them getting it is 1/96059601
It is definitely not a nice number so probably don't try and break in.

Answer:
a) 1,144 rad/min
b) 182.1 rev/min
Step-by-step explanation:
d= 24 inches
radius = 24/2 or 12 inches
speed = 13mi/h
need to convert speed to inches/min
v = Θ * r
1 mile = 63360 inches, and 1 hour = 60 min
13 mi * (63360 in / mi)
= 823680 in / (1 hr * 60 min / hr)
=13728 in/min
Now go back to the equation
13728 in / min = ω * 12 in
13728 /12 = Θ
1,144 rad/min
b) 1 revolution = 2π
w= Θ/2π
w= 1,144rad/ min/2pi rad
w= 182.1 rev/min

What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Genesis mows in 1/6 hour =1/3 lawns
To find, mow per hour,
∴ in 1/6 hours =1/3 lawn,
⇒1 hour = 6×1/3 lawn
⇒1 hour = 2 lawns.

Answer:
x = 3Sides are 6, 8 and 10Step-by-step explanation:
Use Pythagorean to find the value of x:
c² = a² + b²Consider:
a = x + 3, b = 3x - 1, c = 4x - 2Substitute and solve for x:
(4x - 2)² = (x + 3)² + (3x - 1)²16x² - 16x + 4 = x² + 6x + 9 + 9x² - 6x + 116x² - 10x² - 16x + 4 - 10 = 06x² - 16x - 6 = 03x² - 8x - 3 = 03x² - 9x + x - 3 = 03x(x - 3) + (x - 3) = 0(x - 3)(3x + 1) = 0x - 3 = 0, 3x + 1 = 0x = 3, x = - 1/3Positive root is accepted only.
Sides of the triangle:
a = x + 3 = 3 + 3 = 6b = 3x - 1 = 3*3 - 1 = 8c = 4x - 2 = 4*3 - 2 = 10What is the value of cosx/tanx ....
