Number of ways of selecting 4 toy animals 


Hence Tiffany has 70 different ways to select group of 4 unique toys.
1 loaf equals 0.75 lbs of meat; multiply both sides by 8 to get the required number of loaves.
He will need 6 lbs of meat.
Answer:
y=1
Step-by-step explanation:
y = 11x + 1
11x + 12y = 12
Take the right side of the first equation, which is 11x + 1,
since y equals it, put it in parentheses like this (11x + 1)
and put it in place of y in the second equation.
The second equation is
11x + 12y = 12
Take out the y and put in (11x + 1) in place of the y:
11x + 12(11x + 1) = 12
Remove the parentheses by using the distributive principle:
11x + 132x + 12 = 12
Combine like terms on the left
143x + 12 = 12
Subtract 12 from both sides
143x = 0
Divide both sides by 143
x = 0
Now go back and get the very first equation:
y = 11x + 1
And substitute (0) for x:
y = 11(0) + 1
y = 0 + 1
y = 1
Answer:
1 
Step-by-step explanation:
There are a total of 2 friends, if they have 3 cereal bars and want to split it equally then we simply need to divide the number of cereal bars by the number of friends which would give us the number of cereal bars that each individual will get, which will be represented by x
x = 3 / 2
x = 1 
Finally, we can see that each friend will get a total of 1 and a half of a cereal bar.
Step-by-step explanation:
v=l×b×h
300cm²=4×3x×x
300÷12=x²
x=5
3x=3×5=15
a=15×5
