Answer:
see below
Step-by-step explanation:
2x+8y=12 3x-8y=11
If we have to solve by substitution, Take the first equation and divide by 2
2x/2 + 8y/2 =12/2
x+4y = 6
Then subtract 4y from each side
x = 6 -4y
Then substitute this into the second equation
This is best solved by elimination
2x+8y=12
3x-8y=11
----------------
5x = 36
x = 36/5
Answer:
d= -16
Step-by-step explanation:
To answer this question you'll have to first simplify the equation to
0.2d+-1.2=0.3d+5-3+0.1d
then combining like terms you get
0.2d-1.2=(0.3d+0.1d)+(5+-3)
0.2d-1.2=0.4d+2
then subtract 0.4d from both sides leaving you with
-0.2d-1.2=2
then add 1.2 to both sides
-0.2d=3.2
after you divide both sides by -0.2
leaving you with the answer
D= -16
Answer:
The 2 in the hundreths is 10% of the 2 in the tenths
Step-by-step explanation:
We are given the number 15.2201
#The value of 2 in the tenths:

#The value of 2 in the hundredths:

The difference of the 2 in the tenths and in the hundredths is:

Hence, the difference between the 2 in the tenths minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.
