I don't have a calculator with me, but that should get you going
Answer X = 2
Step-by-step explanation:
-30 + -18 - X + - 24,
+ 30 +30
0 6
-18 -x = -6
DIVIDE
3 -x = -1
BRING THE 3 OVER TO THE NEGATIVE ONE
YOU GET
X = 2
Well if you subtract 7/8 from 2/5 you get 19/40 which is 47 muffins Maria can make
Answer:
$15.21
Step-by-step explanation:
17% of $13=0.17*13=2.21
13 (the price of the actual lunch) +2.21= 15.21
Alternatively, you can just do the operation:
13*(1+0.17)=15.21
This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip
Add the total faces: 30 + 20 + 12 = 62
Using the given equation: V + F = E +2
You have F = 62, V = 120
Now solve for E:
120 + 62 = E +2
Simplify:
182 = E +2
Subtract 2 from both sides:
E = 182 - 2
E = 180
It has 180 edges.
