5 (x + 30) is your answer

you will distribute the 5 to both x and 30, as there are 5 thirty's and 5 x's

hope this helps

So first, he could reorder everything, into:

x + x + x + x + x + 30 + 30 + 30 + 30 + 30

And then if you add all the xs and 30s up,

5x + 150.

So therefore we now know it isn't the first, second, or third choices because those aren't remotely close.

The third one, however, is the correct choice, because:

5(x+30), if you use the distributive property, equals 5x + 150.

It's due in 5 hours help
adell [148]

Answer:

Step-by-step explanation:

Things to remember:

1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.

Example:    \frac{2.0}{100}=0.02

2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.

Example:   2.0 × 100 = 200

In this question, 0.014 × 100000 = 1400.000

Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.

A single die is rolled. How many ways can you roll a number that is prime, followed by a 6?
Nutka1998 [239]

Answer:

yes, the answer is 3 because prime numbers are numbers greater than one and can only be multiplied by one to get it, so in this case 2, 3 and 5 are prime, and they are the only ones that can be followed by a 6.
