Answer:
66
Step-by-step explanation:
the order of operations is the acronym PEMDAS which stands for:
P: Parentheses
E: Exponents
M & D: Multiplication and Division
A & S: Addition and Subtraction
we do these in order, from left to right in the equation
for the equation (14 - 8) x (15 - 4), we would start with solving the parentheses
there are 2 sets of parentheses, so we will go from left to right in solving it:
(14 - 8) = 6
(15 - 4) = 11
we replace the values we have found from the parentheses into the equation
6 x 11
now we go through the list
we can already eliminate exponents because there are none in this equation
the next step is multiplication & division, in this equation there is only multiplication, so we multiply 6 x 11 which gives us the answer 66
there is nothing left for us to do at this point, so 66 is our final answer
Step-by-step explanation:
part A:
part B:
yes because it contains a decimal
Answer:
The answer to this equation is D:6
Step-by-step explanation:
6+0.5(6-4(6))=2(0.25(6)-3) is true.
Answer:
k = 3
Step-by-step explanation:
Given
4.5 + 1.5k = 18 - 3k ( add 3k to both sides )
4.5 + 4.5k = 18 ( subtract 4.5 from both sides )
4.5k = 13.5 ( divide both sides by 4.5 )
k = 3
