10 - 4 = x
10 - 4 = 6
x equals 6
Answer:
<em>x is 12 and y is 3</em>
Step-by-step explanation:
Given a parallelogram LMNO,
LM = ON and OL = NM
Given;
ON = 9x - 8
LM = 8x + 4
NM = x - 8, and
OL = 3y - 5
Substitute into the expression
LM = ON
8x + 4 = 9x - 8
8x - 9x = -8 - 4
-x = -12
x = 12
Also OL = NM
3y - 5 = x - 8
3y - 5 = 12-8
3y - 5 = 4
3y = 4+5
3y = 9
y = 9/3
y = 3
<em>Hence the value of x is 12 and y is 3</em>

The relationship between them is that one of them is 600 and the other 60. 60 times 10 is 600 so it is the next multiple of 10 of 60 is 600.
That is the most important relationship. Everything divisible by 60 is divisible by 600 and anything multiple of 600 is a multiple of 60.

Answer:
correct / incorrect / incorrect
Step-by-step explanation:
5a - 8 + 2a² + 2a - 1 ← collect like terms
= 2a² + 7a - 9 ← correct
-------------------------------------
b² + 6b - 4 - (3b + b²) ← distribute parenthesis by - 1
= b² + 6b - 4 - 3b - b² ← collect like terms
= 3b - 4 ≠ 2b² + 3b - 4
---------------------------------------
9c - 4c² - (2c² + c) ← distribute parenthesis by - 1
= 9c - 4c² - 2c² - c ← collect like terms
= - 6c² + 8c ≠ - 6c² + 10c
Another way of writing it is in expanded notation
