Hey there,
Question : <span>How to solve for x 5x-8=18+4,for x=6
Answer :
5x - 8 = 18 + 4
5(6) - 8 = 18 + 4
30 - 8 = 18 + 4
22 = 22
Thus we can say that 6x = 30
6x = 30
x = 30 / 6
= 5
Hope this helps :))

Answer: y=8.5x + 25.5
Step-by-step explanation:
y=mx+b
b= beginning number so thats
25.5 you start there
m= its slope so its 8.5
Answer:
288 pi or 904.22
Step-by-step explanation:
(4/3) × pi × r³
(4/3) × pi × 6³
288pi or
288 × 3.14 = 904.32 units³
Answer:
x1 = 2 -
x2= 2 +
Step-by-step explanation:
x/4 + 6 = 7 + 1/4x
(x^2 - 1)/4x = 1
x^2 - 1 = 4x
x^2 - 4x -1 = 0
x= (4+
)/2 = 2 -
x= 2 +
Answer: T = 4
Step-by-step explanation:
1. Write all the variables down
P = 8 V = 2X N = 2 R = 2X X = 3
2. Since you know that X = 3 substitute it in to find V and R
V = 2X = 2(3) = 6
R = 2X = 2(3) = 6
3. Find PV
PV = P x V
= 8 x 6
= 48
4. Find NRT
NRT = N x R x T
= 2 x 6 x T
= 12 x T
= 12T
5. Find T
PV = NRT
48 = 12T
12T = 48
divide both sides by 12
T = 48 ÷ 12
T = 4
