Answer:
D/z
Step-by-step explanation:
Since D and z are variables, we can express the division as a fraction:
D/z
Let's look at the equation:
0.243x=117.369
Divide each side by 0.243.
X=483
So, the number is 483.
Answer:
y = -1.0
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 4y and subtract 14 from both sides:
1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)
1y + 4y = 9 - 14
Combine like terms:
5y = -5
Isolate the variable, y. Divide 5 from both sides:
(5y)/5 = (-5)/5
y = -5/5
y = -1
y = -1 is your answer.

This equation has one solution which is -1.5
3x+7=-3x-2
+2. +2
3x+9=-3x
-3x. -3x
9= -6x
/-6. /-6
X= -1.5
Answer:
The answer is 7.
Step-by-step explanation:
When two letters in an equation are put together that means you must multiply them. So 5×3=15. y=8 so you subtract 15-8=7.
