Answer:
so x = 5 is not true statement
Step-by-step explanation:
well to prove x = 5 you need to get get alone or solve for x
3x = 10-5 --> 3x = 5
now you need to get x alone do this by dividing 3 by both sides
3x = 5 --> x = 5/3
x = 1.6
Answer:
1:3
Step-by-step explanation:
That ratio would be 5 :15 or 1:3
<span>X/2 = 4/16
This is where you would use cross-multiplication.
Multiply the x with 16 and the 2 with 4.
16x = 8
Now divide everything by 16.
x = 0.5</span>
Answer:
-11
Step-by-step explanation:
The generic solution to ...
- a + b = sum
- a - b = difference
Can be found by adding the two equations:
(a+b) + (a-b) = (sum) + (difference)
2a = (sum + difference)
a = (sum + difference)/2
___
Our particular solution is ...
a = (-44 +22)/2 = -11
The greater of the two numbers is -11.
___
The other number is -33.
