Answer:
Step-by-step explanation:
let x = the number of pounds of cheaper coffee.
Since the merchant is mixing this with more expensive coffee, then
x + 60 = the number of pounds of medium priced mixed coffee.
The equation is gotten from this
+ =
(x)($40) + (60)($90) = (x + 60)($70) or
40x + 5400 = 70(x + 60)
Solve that equation and get x = 40
Answer: 40 pounds of $40 coffee.

which of the following situations describes a postive number
Answer:
B. Going up the elevator 14 floors
Step-by-step explanation:
Choice A can't be right because you are going below sea level (negative).
Choice C can't be correct either because the word "losing" let's you know that it's negative.
Choice D isn't right because if you are taking $20 from your checking account, it would be a negative number.
Hope this helps!
What is the inverse of v(x)= -3/4x - 1/3?
Step-by-step explanation:
v(x) = y = -3/4x - 1/3
y + 1/3 = -3/4x
x = -4/3 × (y + 1/3)
you see ? we only need to show how we calculate x out of y (instead of the normal direction of y or of x).
and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x
y = -4/3 × (x + 1/3) = -4x/3 - 4/9
Simplify: X + x =
5y + y =
Answer:
[tex]x + x = 2x \\ 5y + y = 6y \\ thank \: ou[/tex]

Which equation is an identity?
A. (9x/15) + 27 = (9x/15) + (27/15)
B. 3((x/2) + 16) - 16 = (3/2)x
C. -4(3 - 2x) = -12 - 8x
D. -5((x/15) - 16) - 30 = 50 - (1/3)x
E. 36((3/4)x- 2) + 72 =-72 + 27x
Answer:
C.
Step-by-step explanation:
An equation is an identity if the equation is always true regardless of what value you replace 'x' with.
This means we need to simplify the equations above to see which one will be true for any value of 'x'.
After simplifying equation C, we get -12-8x = -12-8x. Since both sides of the equation are the same, this equation will be true regardless of what value replaces x so this equation is an identity.

How do you solve this?
Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
Hello there!
We are given a function below:
[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]
To find f(-10), substitute n = -10.
[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]
Evaluate the f(-10)
[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]
Recall
Negative × Negative = PositiveTherefore,
[tex] \displaystyle \large{f( - 10) = 74}[/tex]
f(-10) = 74

Topic: Functions
the perimeter of a rectangular tray is 60in the length of the tray is double the width of a tray determine the dimensions of the rectangular tray
Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in

Answer:
x = 19.6
Step-by-step explanation:
If we need to find the value of x then first we need to
(7x-25) + (3x +9) = 180 (angles at the same side of transversal will be equal to 180 degree )
10x -16 = 180
10x = 180 +16
10x = 196
x = 196/10
x = 19.6

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked

Which of the following is a terminating decimal?
Together, two pipes can fill a tank in 3 hours.
One pipe alone can fill the tank in 5 hours.
How long does it take for the other pipe to
fill the tank alone?
Answer: 7.5 (h)
Step-by-step explanation:
Let say
a the outflow of the first pipe
b the outflow of the second pipe
T the volume of the tank.
x the time for filling with the second pipe
two pipes can fill a tank in 3 hours: a*3+b*3=T
One pipe alone can fill the tank in 5 hours : a*5=T
3*b=T -3a ==> 3b= 5a*3a=2a
b=2a/3
b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1
x=15/2 = 7.5 (hours)

Please solve this if you can
Answer:
d = 3
Step-by-step explanation:
(7d+3)/4 = 6
Multiply each side by 4
(7d+3)/4*4 = 6*4
(7d+3) = 24
Subtract 3 from each side
7d+3-3 = 24-3
7d = 21
Divide by 7
7d/7 = 21/7
d = 3
