Pemdas? OK so how I would remember it by is "Please Excuse My Dear Aunt Sally"
So.. Parenthesis, Exponent(s), Multiplication, Division, Addition, Subtraction..
Example~~~~~
(
+ 4) ×12÷4 - 1= ? so first do parenthesis and then the exponents then add it to 4 and the divide 12 and 4 and then subtract 1 which is 2.. Then after take two and 13 and multiply which is 26~
Hope this helps! :)
Answer:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|
Step-by-step explanation:
Since DH=HF you set x+3=3y
<span>GH=HE so 4x-5=2y+3 </span>
<span>This gives you a system and I solved by substitution so I got x alone in the first equation-> x=3y-3 </span>
<span>then I plugged this x into the second equation so </span>
<span>4(3y-3)-5=2y+3 </span>
<span>12y-12-5=2y+3 </span>
<span>12y-17=2y+3 </span>
<span>10y=20 </span>
<span>y=2 </span>
<span>plug y into the first equation to find x </span>
<span>x=3(2)-3 </span>
<span>x=6-3 </span>
<span>x=3 </span>
<span>c. x=3, y=2</span>

a(b+c)=ab+ac
9(2+5m)=9(2)+9(5m)=18+45m
Answer:
125 people
Step-by-step explanation:
P( green) = number of green / total
= 25/120
=5/24
Multiply this probability by 600
5/24 * 600 =125
