Solve the system using elimination
Answer:
x = 5
y = 1/4
Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are
(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2
-10a - 16b = -66
-20b = - 80
b = 4 5a + 8(4) = 33
5a + 32 = 33
5a = 1
a = 1/5
a = 1/x = 1/(1/5) x = 5
b = 1/y = 4 y = 1/4

Given that, nine actors audition for four different parts in a play.
What is a combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by nCr and it is given by, nCr=n!/r!(n−r)!,where 0 ≤ r ≤ n.
Here, 9 actors audition for 4 different parts in a play is
9C4 = 9!/4!(9-4)!
= (9×8×7×6×5!)/(4×3×2×1)5!
= (9×8×7×6)/(4×3×2×1)
= 3×2×7×3

How do you do 4 divided by 0.8 in place value
Answer:
5
Step-by-step explanation:
because that is the correct answer
4 divided by 0.8 is equal to 5.
To divide 4 by 0.8 using place value, you can follow these way
Convert the decimal divisor, 0.8, into a whole number by multiplying both the tip and the divisor by a power of 10.
Since there's only one decimal place in0.8, you can multiply both figures by 10 to exclude the decimal
0.4 x 10 = 40( multiplying the tip by 10)
0.8 x 10 = 8( multiplying the divisor by 10)
Now we've the division problem as 40 divided by 8.
Divide the converted tip by the converted divisor
= 40 ÷ 8
= 5
Thus, 4 divided by 0.8 is equal to 5.
