Answer:
3 =n
Step-by-step explanation:
-3 +3(n+8)= 2(1 + 6n) - 8
Distribute
-3 +3n +24 = 2 +12n -8
Combine like terms
21+3n = 12n -6
Subtract 3n from each side
21+3n-3n = 12n-3n -6
21 = 9n -6
Add 6 to each side
21+6 = 9n-6+6
27 = 9n
Divide each side by 9
27/9 = 9n/9
27/9 =n
Divide the top and bottom by 3
3 =n
Answer:
<h2>≈ 13</h2>
Step-by-step explanation:
First ,we round 1.79 to the nearest whole dollar:
since 7 ≥ 5 then 1.79 rounded to the nearest whole dollar is 2
now ,we can estimate the greatest number she can download:
26/2 = 13
Answer:
The value of the constant of proportionality r is 1
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Find the value of the constant of proportionality r
For x=5.8, y=5.8
substitute
The linear equation is
therefore
The value of the constant of proportionality r is 1
3(x + 4) = x/2 - 8
First, we can multiply both sides by 2:
6(x+4) = x - 16
6x + 24 = x - 16
Isolate x:
5x = -16 - 24
5x = -30
x = -6
