Answer:
3 = x
Step-by-step explanation:
0 > 3x - 3 - 6
You want to group up the -3 and -6 first
0 > 3x - 9
Then you want to add 9 to each side to cancel out the negative 9 on one side.
0 > 3x - 9
+9 +9
9 > 3x
Now you just divide by 3 on each side
3 = x
<span>4y - 12x = 20
4y = 12x + 20
y = 3x + 5
parallel has same slope = 3
answer
</span><span>A. Y = 3x - 1 </span>
Answer:
Step-by-step explanation:
we know that
Let
x-------> the number of nickels
y-------> the number of dimes
------> isolate the variable y
--------> equation A
------> multiply by both sides
-------> equation B
Substitute equation A in equation B and solve for x
That would be -9 (because theres a +9y in first equation).
Answer:
9.0333
Step-by-step explanation:
Given the mixed number:
To find:
The number to four decimal places.
Solution:
First of all, let us learn the method converting the mixed fraction number to a fractional number.
If a mixed fraction is of the form:
Then first, we will multiply with and then add to get the numerator of the simple fraction.
Denominator will be the same i.e. .
Therefore
can be written as:
Numerator = = 271
Denominator will be the same i.e. 30
Simple fraction equivalent will be:
And up to, 4 decimal points, the number can be written as:
<em>9.0333</em>
