1 one is the answer
2 is the answer either
all the equations are in it's simeplest form
Answer:
That is true.
Step-by-step explanation:
A supplementary angle equals 180 degrees and and a right angle is 90, so 90+90=180
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
(left to right)
4²-(3.1+6.4)+4.5
According to PEMDAS, we will do what is inside the parenthesis.
3.1+6.4 = 9.5
<em>4²-9.5+4.5</em>
Then we do figure out the exponent.
4² = (4)(4) = 16
<em>16-9.5+4.5</em>
Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.
16-9.5 = 6.5
<em>6.5 + 4.5 = 11</em>
11 is your answer :)

“Divide 40 by 9” means 40÷9
Axel did 9÷40
9 goes outside the dog house (⬜️)
9 can’t go into 4 so move to the next number
9 goes into 40 4 times.
9 times 4 equals 36
40 minus 36 equals 4
There are no other numbers under the house can’t go into four and 9 can’t go into 4. That means there is a remained of four.
