Answer:
x=104
Step-by-step explanation:
2/5(x-4)=20
2/5x-8/5=20
2/5x=20+8/5
=21/3/5
x=21/3/5÷2/5
=104
Answer:
Step-by-step explanation:
The first step is to take p on both sides:

On the right hand side, cancel p and -p, since
. The equation will be:

Then, divide both sides of the equation by p*t:

On the right hand side, p*t can be cancelled:

Answer: x = -7
Step-by-step explanation:
2.5x+10=x-0.5
Collect like terms
2.5x-x= -0.5 -10
1.5x= -10.5
X= -10.5/1.5
X= -7
Answer:
243.01.
Step-by-step explanation:
The first term (a) = 324.
The common ratio (r) = -108/324 = -1/3.
So sum of 9 terms is:
S(9) = 324 * (1 - (-1/3)^9) / ( 1 - (-1/3)
= 324 ( 1 - (-0.00005076)) / 4/3
= 324 * 1.00005076 / 1.33333
= 243.012.
