Hallie bikes 1 5/8 km before lunch 6 1/4 km How much farther does hallies bike after lunch than before lunch? Express your answe

kondaur [170]

Distance biked before lunch = 1 $\frac{5}{8}$ km (the number is written in mixed fraction)

⇒ Distance biked before lunch = $\frac{13}{8}$

Distance biked after lunch = 6 $\frac{1}{4}$ km (the number is written in mixed fraction)

⇒ Distance biked after lunch = $\frac{25}{4}$

We need to determine how much farther does Hallie bike after lunch than before lunch

Extra distance biked after lunch vs. before lunch = $\frac{25}{4}$ - $\frac{13}{8}$

⇒ Extra distance biked after lunch vs. before lunch = $\frac{50-13}{8}$

⇒ Extra distance biked after lunch vs. before lunch = $\frac{37}{8}$

⇒ Extra distance biked after lunch vs. before lunch = 4 $\frac{5}{8}$ (in mixed fraction)

Hence, Hallie biked 4 $\frac{5}{8}$ km extra after lunch vs. before lunch.

Which of the following shows the prime factorization of 200 using exponential notation?

Vilka [71]

Answer:

The prime factorization of 200 using exponential notation is $2^{3}\times 5^{2}$ .

Step-by-step explanation:

First, we decompose the number given on statement by applying prime numbers in ascending order. We see that 200 is an even number, therefore, we infer that smallest prime number within is 2.

1) $\frac{200}{2} = 100$ (Even number)

2) $\frac{100}{2} = 50$ (Even number)

3) $\frac{50}{2} = 25$ (Even number)

4) $\frac{25}{5} = 5$ (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

5) $\frac{5}{5} = 1$ (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

Now, we construct the prime factorization using exponential notation:

$200 = 2^{3}\times 5^{2}$

The prime factorization of 200 using exponential notation is $2^{3}\times 5^{2}$ .

Answer:

Looking at the question and goin step by step

we get to know that equation formed wud be ->

product of nine and a number - 9*x = 9x

added to 6 => 9x+6

gives us 24

9x + 6 = 24

now 9x = 18 and x = 18/9 = 2

and now keeping x value = 9 *(2)+6 we get 18+6 = 24

so lhs = rhs = 24

9x+6=24 option a
