Answer:
Step-by-step explanation:
132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have 540 degrees. Remove the brackets.
132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540 Collect like terms
13x + 241 = 540 Subtract 241 from both sides.
13x = 540 - 241
13x = 299 Divide by 13
x = 299/13
x = 23
<P = 4x + 2
<P = 92 + 2
<P = 94
If we take 12450 to be the 100%, what is 622.50 off of it in percentage then? let's check.
Answer:
72g
Step-by-step explanation:
I hope it's right I figured it out by common factor
3(x+2)-6x+6<0 "< is like equal sign bruv"
3x+6-6x+6<0 "do group so ( ) so multiply and bring everything else down"
-3x+12<0 "add all like terms so "3x-6x" and "6+6" since they cancel out you get "
-3x< 0-12 "to get rid of 12 you subtract 12 and subtract it from the other side so 0 aswell
-3x<-12 "you would end up with this"
-3x/-3 < -12/-3 "since dividing or multiplying by a negative you flip the arrow"
x > 4 "this is the answer"
