Answer:
A.5
B.12
C.42
Step-by-step explanation:
A. 5th time meaning 72-(0.75*5)=68.25
B.72-63=9 9/0.75=12
C.40*0.75=30 72-30=42
Answer:
e = 9
Step-by-step explanation:
ok e is just x, so we have to get it alone
4e - 10 = 2e + 8
We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..
2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..
2e = 18
18/2 = 9
simple explanation
4e - 10 = 2e + 8
2e = 18
e = 9
(does that make sense)
Angle b is 31
Angle ab is 72
Angle ca is 90+31 so 121
Answer:
D (last one)
Step-by-step explanation:
You figure out the ordered pair for E which is (3,-4)
Then you apply the rule given in the instructions.
so you do 3+8= 11 so x = 11
then -4+5= 1 so y = 1
So you get (11,1)
