Answer:
cubes are 3-d while squares are 2-d so in order to solve them you need different equations.
Answer:
x = 3 or y = -3
Step-by-step explanation:
To find x, substitute y with a 0.
0=x-3. Minus the x on both sides and x will equal 3
To find y, substitute x with a 0.
y=0-3. 0-3 equals -3 which means that y will equal -3

<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The given expression can be simplified as,
A.) 7 3/4 - (√11)/5 = (155-4√11)/20
B.) 7 3/4 ÷ (√11)/5 = 155/(4√11)
C) 7 3/4 + (√16)/5 = 166/20
D.) 7 3/4 + (√16)/5 = 31/5
The option that will result in a rational number is C and D.

Answer:
The Answer is: the Number is -2
Step-by-step explanation:
Let n = the number.
Five times the number minus 10 is less than 6 times the number minus eight:
5n - 10 = 6n - 8
-1n = -8 + 10
-n = 2
n = -2, the value of the number is -2.
Proof:
5(-2) - 10 = 6(-2) - 8
-10 - 10 = -12 - 8
-20 = -20
Hope this helps! Have an Awesome Day!! :-)
