Answer: The answer is A. 1.

Step-by-step explanation:

-11 + 3(b + 5) = 7 Start by distributing the 3. 3xb and 3x5.

-11 + 3b + 15 = 7 Next combine all like terms. -11 + 15.

4 + 3b = 7 You want to get b by itself so move the 4 using subtraction. ..................................4-4 and 7-4

3b = 3 B is still not by itself. Now we must divide 3 by 3 and 3 by 3.

b = 1

Hope this helped. I explained the best I could.

Joe is playing a game with a regular die. If the number that turns up is even, he will gain 5 times the number that comes up. If

Answer:

30 dollars

Step-by-step explanation:

The question states that if an even number comes up then Joe will win 5 times of the number that shows up for example, if 2 comes up he will win 5×2 dollars i.e., 10 dollars. If an odd number shows up he will lose 10 times the number which i.e. if 1 shows up he will lose 1×10 = 10 dollars

It says in the question that Joe tosses a 3 which is an odd number so he will lose 10 times of 3

So he will lose 10×3 = 30 dollars.

What is 2/3, 7/6, 3 1/9, and 5 5/18 written as a decimal?

Paul [167]

Step-by-step explanation:

$\frac{2}{3} = 2 \times \frac{1}{3} = 2 \times 0.333 = 0.666 \\ \\ \frac{7}{6} = 7 \times \frac{1}{6} = 7 \times \frac{1}{2} \times \frac{1}{3} = 7 \times 0.5 \times 0.333 = 1.1655 \\ \\ 3 \frac{1}{9} = 3 + \frac{1}{9} = 3 + ( \frac{1}{3} \times \frac{1}{ 3} ) = 3 + (0.333 \times 0.333) = 3 \times 0.11088 = 3.11088 \\ \\ 5 \frac{5}{18} = 5 + (5 \times \frac{1}{18} ) = 5 + (5 \times \frac{1}{3} \times \frac{1}{3} \times \frac{1}{2} ) = 5 +(5 \times 0.333 \times 0.333 \times 0.5) = 5 + 0.27722 = 5.27722$
