solve the equation,(112 - 38) x 14 divided by 7 + 142
may some one please help me with this complicated question???PLEASE
PLEASE
(112 - 38) x 14 divided by 7 + 142
74 * 14 / 149
1036 / 149 = 6.953
but the answer choices on my homework sheet said
A)178
B)278
C)290
D)390
there is no 6.953!!!
Most textbooks will give a the mnemonic BEDMAS to remember the order of operation
B -- brackets done first
E -- any exponents
D -- division in the order they come
M --multiplication in the order they come
A -- addition in the order they come
S -- subtraction in the order they come
= 74 * 14/7 + 142
= 74 * 2 + 142
= 148 + 142
= 290

i remeber it as
Please Excuse My Dear Aunt Sally
Please/P = Parenthesis
Excuse/E = Exponents
My/M = Multiplication
Dear/D = divide
Aunt/A = addition
Sally/S = subtraction
To solve the equation, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
Let's go step by step:
Step 1: Simplify within the parentheses:
(112 - 38) x 14 divided by 7 + 142
112 - 38 = 74
The equation now becomes:
74 x 14 divided by 7 + 142
Step 2: Perform multiplication and division (from left to right)
74 x 14 = 1036
1036 divided by 7 = 148
The equation now becomes:
148 + 142
Step 3: Perform addition
148 + 142 = 290
Therefore, the solution to the equation (112 - 38) x 14 divided by 7 + 142 is 290.
