The goal of any equation is to get the VARIABLE by itself on one side of the equation.
Step-by-step explanation:

<u>This means that the side length of the cube is 3 units. The volume, which we previously stated was equal to s3, must then be 33, or 27 cubic units. The answer is 27.</u></h3>
Answer:
25 degrees
Step-by-step explanation:
Haha, awesome! Just did a problem like this!
All angles add up to 180, so set it up like this:
2x + 1 + 5x + 5 + 90 = 18
Combine like terms.
7x + 96 = 180
7x = 84
x = 12
Plug x back into 2x + 1
2(12) + 1
24 + 1
= 25 degrees
While we're at it...
5(12) + 5
60 + 5
= 65 degrees (for the other angle)
25 + 65 + 90 = 180
Math checks out & we're good to go!
Hope this helped. :) <3
Answer:
1/8
Step-by-step explanation:
When you are dividing by fractions you flip and multiply this also go's for when you multiply a fraction you flip and divide. what makes it easier is to put it in decimal form so 1/4 = .25 and 1/2 = .50 so what is 25/50? so it would come back to .125 which is equal to 1/8. If you are not very good at math just ignore this lol
Answer:
DA= $800 and DB= $1200
Step-by-step explanation:
Equation I (Interest of Bank A):
IA= 0.06/year*DA *1year (DA= Deposit in Bank A)
IA= 0.06*DA
Equation II (Interest of Bank B):
IB= 0.08/year*DB *1year (DB= Deposit in Bank B)
IB= 0.08*DB
Total interest:
TI=IA+IB=$144
Total deposit:
TD= DA +DB= $2000
Adding equations I and II:
IA+IB = 0.06DA +0.08DB
$144= 0.06DA+0.08DB
(DB= $2000-DA)
When replacing DB:
$144= 0.06DA + 0.08($2000-DA)
Applying distributive property:
$144= 0.06DA + (0.08*$2000) -0.08DA
$144= -0.02DA + $160
0.02DA= $160-$144
0.02DA = $16
DA= $16/0.02
DA= $800
DB= $2000-$800
DB= $1200
