Solve for n. 170-4n=120
Answer:
n = 12.5 or 25/2
Step-by-step explanation:
170-4n = 120
1. Subtract 170 from both sides to isolate -4n.
-4n = -50
2. Divide both sides by -4 to isolate the n.
n = 12.5 or 25/2
Hope this helped!
Answer:
12.5
Step-by-step explanation:
170 - 4n = 120
-170 -170
-4n = -50
4n = 50
n = 12.5

some number is added to itself the result is multiplied by eight is four what is that number
Answer:
X=1/4
Step-by-step explanation:
(x+x)*8=4
(2x)*8=4
16x=4
X=4/16=1/4
Answer:
0.25
Step-by-step explanation:
First...
Assume that the number is x and make an equation.
(x + x) 8 = 4
Next...
Add.
(2x) 8 = 4
After that...
Divide.
2x = 4/8 so 2x = 1/2
Finally...
Divide more
x = 1/4 or 0.25
So your answer is 0.25.
I did double-check.

Daniela and Jack are hiking a steady incline. They use their GPS device to determine their elevation every 15 minutes. At 15 minutes and 30 minutes they were at elevations of 10,300 and 10,900 feet, respectively. Write an equation expressing their elevation in relation to time.
Answer:
[tex]h=40t+9700[/tex]
where the elevation, h, is in feet and time, t, is in minutes.
Step-by-step explanation:
At the time, [tex]t_1=15[/tex] min, the elevation, [tex]h_1= 10,300[/tex] feet and
at the time [tex]t_2= 30[/tex] min, the elevation, [tex]h_2=10,900[/tex] feet.
As they are hiking a steady incline, so the change in the elevation with respect to time will be constant.
So, there will be a linear relationship between the elevation and the time.
Let [tex]h[/tex] be the elevation at any time instant [tex]t[/tex], so the linear relation among these quantities is
[tex]h=mt+C_0\;\cdots(i)[/tex]
where [tex]m[/tex] is the rate of change of elevation with respect to time and [tex]C_0[/tex] is constant.
The change in the elevation, [tex]\Delta h=h_2-h_1= 10,900-10,300=600[/tex] feet.
and the change in time, [tex]\Delta t=t_2-1_1=30-15=15[/tex] min.
So, change in the elevation in unit time,
[tex]m=\frac{\Delat h}{\Delta t}=\frac{600}{15}=40[/tex] feet/min.
Now, from equation (i)
[tex]h=40t+C_0[/tex]
As the elevation, [tex]h=h_1[/tex] at time [tex]t=t_1[/tex], so
[tex]10,300=40\times15+C_0[/tex]
[tex]\Rightarrow C_0=9700[/tex]
Hence, the required equation is
[tex]h=40t+9700[/tex]
where the elevation, [tex]h[/tex], is in feet and time, [tex]t[/tex], is in minutes.

calculate E, the amount of euros that has the same value as D U.S. dollars, using the equation E=17/20D=
The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
E=17/20(1)
E=1/20=0.85
0.85 Euros have the same amount as 1 U.S dollar.

q log a -3 log b
Condense logarithm
Answer:
Step-by-step explanation:
q log a is equivalent to log a^q. Note: This assumes that the base of your logarithmic system is 10.
-3 log b is equivalent to log b^(-3)
and so q log a -3 log b in condensed logarithm form is
log {a^q*b^(-3)}
a^q
or log -----------------
b^3
There is a daily fee for renting a moving truck, plus a charge of $0.50 per mile driven. If driven 48 miles, it costs $64 to rent a truck.
Answer:
The total would be $88
Step-by-step explanation:
First multiply $0.50 and 48 miles
$0.50x48=$24.00
Then add $24.00 and $64.00
$24.00+$64.00=$88.00
Hope this helps :)

What is the equation of a line with a
slope of -2 and crosses the vertical axis
at the point (0, 5)?
Answer:
y=-2x+5
Step-by-step explanation:
the slope is m and the y-intercept is b in the form y=mx+b, and -2 is the slope and 5 is the y-intercept in this equation, so y=-2x+5
Answer:
y=-2x+5
Step-by-step explanation:
y=mx+b
m is the slope which is -2
b is the y intercept which is given in the problem, 5
through: (-3, 2), parallel to y = -
4
5
x + 1
Answer:
[tex]y=\frac{-4}{5}x-\frac{2}{5}[/tex]
Step-by-step explanation:
passes through (-3,2), parallel to y=-4/5x + 1
[tex]y-y_{1} =m(x-x_{1} )\\y-2 =\frac{-4}{5} (x+3)\\y-2=\frac{-4}{5}x-\frac{12}{5}\\y=\frac{-4}{5}x-\frac{2}{5}[/tex]

3-(2)/(9)b=(1)/(3)b-7
Answer:
b=18
Step-by-step explanation:
factorise
a) 4p²-81
b) x²-13x+36
Answer:
A = (2p + 9) (2p - 9)
B = (x - 9) (x - 4)
Step-by-step explanation:
For A : Rewrite 4p^2 as (2p)^2.
(2p)^2−81
Rewrite 81 as 9^2.
(2p)^2−9^2
Since both terms are perfect squares, factor using the difference of squares formula, a^2 − b^2 = ( a + b ) ( a − b ) where a = 2p and b = 9 .
(2p + 9) (2p − 9)
For B : Consider the form x^2 + bx + c . Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 36 and whose sum is − 13 .
-9, -4
(x - 9) (x - 4)

Hello! I need help with my math homework! I need it ASAP.
6x - 3 = -18 + x
Answer:
x = -3
Step-by-step explanation:
6x - 3 = -18 + x
Subtract x from each side
6x-x - 3 = -18 + x-x
5x -3 = -18
Add 3 to each side
5x-3+3 = -18+3
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
Solve for m.
m+9=-2
m=?
Answer:
