I need help on the question up here
2x + 4a = 10
2x = 10 - 4a
x = 5 - 2a
What is 4=2x as a improper fraction or integer
Answer:
2/4 or 1/2
Step-by-step explanation:
Divide both sides by 2 and you get x=2/4. You can simplify further by dividing 2 and 4 by 2 to get 1/2
Solve for n in the literal equation a(n − 5) + 6 = bn.
Answer:
(6-5a)/(b-a) = n
Step-by-step explanation:
a(n − 5) + 6 = bn
Distribute
an -5a +6 = bn
Subtract an from each side
an -5a+6 -an = bn-an
6-5a = bn-an
Factor out n
6-5a = n(b-a)
Divide each side by (b-a)
(6-5a)/(b-a) = n
Answer:
[tex]a(n - 5) + 6 = bn \\ an - 5a + 6 = bn \\ an - bn = 5a - 6 \\ n(a - b) = 5a - 6 \\ n = \frac{5a - 6}{a - b} \\ thank \: you[/tex]
Need help with #12
Please help
Step-by-step explanation:
If the figure is triangle then,
Let PR be x
So,
PQ+QR+PR= 180 (Sum of all the angles of the triangle)
Therefore,
6x+25+16-3x+x=180
4x+36=180
4x= 180/36
x= 144/4
X= 36
NOW,
PQ= 6x+25
= 6(36)+25
= 216+25 = 241= PQ.
QR = 16-3x
= 16-3(36)
= 16-108
= -92
PR = 36
hope it helps
Answer:
PR = 36

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)

if f(x)=4x-5 what is the value of f(2)
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
Value of Polynomial :The value of a polynomial p(x) or f(x) at x = α is obtained by putting x = α in p(x) or f(x) and it is denoted by p(α) ...!
Required Solution :Let f(x) = 4x - 5
⇒f(2) = 4(2) - 5
= 4 × 2 - 5
= 8 - 5
= 3
Hence, If f(x) = 4x-5 then the value of f(2) will be 3 ...!

f(2) = 3Step-by-step explanation:
f(x) = 4x-5f(2) = (4×2)-5f(2) = 8-5f(2) = 3HOPE THIS HELPS YOU......the quotient of five times a number 7 is no more than 10
Answer:
[tex]x \ge3.5[/tex]
Step-by-step explanation:
First, write the given in the form of a mathematical equation rather than words. I'll call the mystery number given in the question [tex]x[/tex]:
[tex]\frac{5*7}{x} \leq 10[/tex]
Simplify:
[tex]\frac{35}{x} \leq 10[/tex]
Solve for x:
[tex]\frac{35}{x} *x\leq 10*x[/tex]
Simplify the fraction:
[tex]35\leq 10x[/tex]
Divide by 10 to isolate x:
[tex]\frac{35}{10} \leq x[/tex]
Flip the equation around to make it easier to read:
[tex]x \ge \frac{35}{10}[/tex]
Simplify the fraction:
[tex]x \ge \frac{7}{2}[/tex] or [tex]x \ge3.5[/tex]

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.

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
