Answer: x=10
Step-by-step explanation:
The angles added together are going to be 360
360=120+11X+13X
240=24x
x=10
Answer:
b=4, h=5
Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5
Answer:
3/10
Step-by-step explanation:
Part I: 2/5 = 4/10
Part II: 3/4(2/5) = 6/20 or 3/10
Part III: 10/10 - (4/10 + 3/10) = 3/10
Answer:
There is a 5.56% chance of rolling a three.
Answer:
pretzels = 10
drinks = 6
Step-by-step explanation:
Let d = number of drinks
p = number of pretzels
4d+ 4.75p = 71.50
d+p = 16
Solving this for d
d = 16-p
Substituting this into the first equation
4(16-p)+ 4.75p = 71.50
Distribute
64 - 4p +4.75p = 71.50
Combine like terms
64 +.75p = 71.50
Subtract 64 from each side
64 -64 +.75p = 71.50-64
.75p = 7.5
Divide each side by .75
.75p/.75 = 7.5/.75
p =10
Now we can find the number of drinks
d = 16-p
16-10
