Answer:
1) 24
2) 36
3) 144
Step-by-step explanation:
Order of operations are the operations in which you must complete multiple-operation equations.
Here's an acronym to help you remember the order of operations.
PEMDAS:
- Exponentiation (exponents)
----------------------------------------------------------------------------------------------------------------
7 × 3 + (18 - 9) ÷ 3
First, as stated by the order of operations, solve what is in parenthesis.
7 × 3 + (18 - 9) ÷ 3
7 × 3 + 9 ÷ 3
-------------------------------------------------------------------------------------------------------------
There are no exponents.
Further, we solve the multiplication problem(s).
7 × 3 + 9 ÷ 3
21 + 9 ÷ 3
-------------------------------------------------------------------------------------------------------------
Moreover, we solve the division problem(s).
21 + 9 ÷ 3
21 + 3
-------------------------------------------------------------------------------------------------------------
Lastly, we solve the remaining addition problem(s).
21 + 3
24
-------------------------------------------------------------------------------------------------------------
Now, we solve the remaining equations using order of operations (PEMDAS).
(7 × 3) + (18 - 9 ÷ 3)
21 + (18 - 9 ÷ 3)
21 + 18 - 3
39 - 3
36
-------------------------------------------------------------------------------------------------------------
7 × (3 + 18) - 9 ÷ 3
7 × 21 - 9 ÷ 3
147 - 9 ÷ 3
147 - 3
144
Equation of the line:
y = -4x + 1
Add the cost of all the items together
5.45 for cups + 4.75 for plates + 11.50 for the punchbowl + 2(7.80) for baloons = 37.3 Then divid 37.3 by the 10 friends, and each will pay $3.73
Answer:
f(6) = 0
x = 3 when f(x) = 2
Step-by-step explanation:
f(6) = -2/3(6) + 4
f(6) = -4 + 4
f(6) = 0
2 = -2/3x + 4
-2 = -2/3x
-2x = -6
x = 3
Just redraw it at a 180 degrees , it doesn’t say whether it goes clockwise or counterclockwise so I can’t give the exact answer
