I'm assuming they are equivalent...

$5m + 1 = 3m + 7$

Solve for m and get 3.

The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?

lidiya [134]

This one is a bit confusing but I'll try to answer. Since the sum is given and one of the addend is given, we need to perform subtraction to get the other addend.

8d⁵ - 3c³d² + 5c²d³ - 4cd⁴ + 9 ⇒ SUM
- 2d⁵ - c³d² + 8cd⁴ + 1 ⇒ 1ST ADDEND
6d⁵ - 2c³d² + 5c²d³ -12cd⁴ - 8 ⇒ 2ND ADDEND

Answer:

Step-by-step explanation:

Break the problem up into two

Ignore the -1 for now

2+2=4 because if you separate 2 and 2, you get four ones, therefore it's four

Now that you have four, subtract 1

And you got 3

Two number cubes are rolled sequentially. What is the probability that the first number cube shows a five and the other number c

nexus9112 [7]

The probability of first number cube shows a five and the other number cube shows an even number is $\frac{1}{12}$ .

Solution:

Two cubes are rolled sequentially.

Sample space when two dies are rolled

$=\left\{\begin{array}{l}{(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)} \\{(2,1),(2,2),(2,3),(2,4),(2,5),(2,6)} \\{(3,1), 3(, 2),(3,3),(3,4),(3,5),(3,6)} \\{(4,1),(4,2),(4,3),(4,4),(4,5),(4,6)} \\{(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)} \\{(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}\end{array}\right\}$

Number of sample space = 36

Even numbers getting when two cubes rolled are 2, 4, 6.

First number cube shows a five and the other number cube shows an even number = {(5, 2), (5, 4), (5 6)}

Number of first number cube shows a five and the other number cube shows an even number = 3

Probability of first number cube shows a five and the other number cube shows an even number

$=\frac{\text{Number of outcomes}}{\text{Total number of sample space}}$

$$=\frac{3}{36}$

$$=\frac{1}{12}$

Hence, the probability of first number cube shows a five and the other number cube shows an even number is $\frac{1}{12}$ .
