The median is 32; list numbers least to greatest, which ever is in the middle is the median
1. 4n + 28
2. 30-10x
3. 3m+3n
4. 8+2j
Answer:
-0.5
Step-by-step explanation:
Use the simultaneous equations method:
x - 4y = 6
3x + 4y = 10
Add these two equations together to cancel out 'y':
4x = 16
Divide both sides by 4:
x = 4
substitute this value into one of the equations:
(4) - 4y = 6
Subtract 4 from both sides:
- 4y = 2
Divide both sides by -4:
y = -0.5
goodluck!
Answer:
<h2><u><em>
x =</em></u><u><em> </em></u><u><em>
3.75</em></u></h2><h2><u><em>
or</em></u></h2><h2><u><em>
x = 3 3/4</em></u></h2>
Step-by-step explanation:
4x - 7 = 8
What is the value of x? Show your working.
4x - 7 = 8
4x = 8 + 7
4x = 15
x = 15 : 4
x = 3.75
or
x = 3 3/4
--------------------
check
4 * 3.75 - 7 = 8
15 - 7 = 8
8 = 8
the answer is good
