Answer:
121 1/2
Step-by-step explanation:
27/d = 4.5
*27 *27
d = 121.5
d = 121 1/2
Multiply 912 x 512 x 3 = ? then divide your answer by 12 .
Answer:
a = -14
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, divide 5 from both sides:
(5(a + 3))/5 = = (-55)/5
a + 3 = -55/5
a + 3 = -11
Next, fully isolate a by subtracting 3 from both sides:
a + 3 (-3) = -11 (-3)
a = -11 - 3
a = -14
a = -14 is your answer.
