Answer:

100,000

Step-by-step explanation:

[tex]10^{5}[/tex] = 10 × 10 × 10 × 10 × 10

10 × 10 × 10 × 10 × 10 = 100,000

Answer:

9.5

Step-by-step explanation:

improper to mixed fraction

[tex]\sf \dfrac{19}{2} = 9\dfrac{1}{2}[/tex]

Long division work out:

explanation using sentences:

18 is divisible by 9 = 2, left 1, so 1 divided by 2 is 0.5,   total: 9 + 0.5 = 9.5

Recheck: 9.5 * 2 = 18 + 1 = 19

Step-by-step explanation:

4*6 - 5*0 = 24

24 - 0 = 24

24 = 24

Answer:

I think it would be 4,8

Step-by-step explanation:

Hopes this helps

Step-by-step explanation:

first derive a formula from that expression

y=kx

in this case k its a constant so we will find a constant first in order to derive a formula

substitute the variables with numbers been given

5=k(8) then make k subject of the formula

k=58 then make a formula from the constant

y= 58x

now this is your direct linear equation y= 58x

then use that equation in order to find the x value

finding x value, substitute the formula with the value given in this case y=15

then

y= 58x

15= 0.625x

150.625=x

24=x

therefore x =24

Answer: Antonio and Josue have 40 tickets left

Step-by-step explanation:

2 x ( 3 x 15 ) + ( 2 x 10 )

3 x 15 = 45

2 x 10 = 20

2 x 45 = 90

90 + 20 = 110

150 tickets is what they started with and they used 110 tickets 150 - 110 equals 40

It should be 110

2 x ( 3 x 15 ) + ( 2 x 10 )

3 x 15 = 45

2 x 10 = 20

2 x 45 = 90

90 + 20 = 110

110 = 40

Answer:

79/100 should be right

Step-by-step explanation:

Answer:

20/100+59/100=79/100

Step-by-step explanation:

100/10=10

ten is what they have in common

what you do to the bottom you have to do to the top

2x10=20

10x10=100 so 20/100 is equivalent to 2/10

Answer:

To factor out -1/3 out of the expression -1/3x - 8, first divide -8 by -1/3 to get 24. Now just put 24 in the place of -8 in the original expression. Your final answer should be -1/3(x + 24). Hope this helps and have a phenomenal day!

Step-by-step explanation:

Answer:

1/3(x-7)

Step-by-step explanation:

If you divide both the x value (1/3) and the constant value (7/3) by 1/3, you will get 1/3(x-7).

Answer:

5/12, 6/12, 7/12, 8/12, mm might fit.

Step-by-step explanation:

make 6/8 and 1/3 the same fractions by finding the least common multiple (which is 12)  so 6/8 becomes 9/12 and 1/3 becomes 4/12. and then all the fractions between 4/12 and 9/12 might fit.

Answer:

C

Step-by-step explanation:

A division equation can be rephrased (i guess thats what you call it) into fraction form. The equation for C is 3 divided by 8, which can be put into fraction form as 3/8. Hope this helps!

Answer:

The answer is C

Step-by-step explanation: When your doing something like this, it's best to be practical and pay attention to the wording

A says 16 pieces of candy shared with 6 friends which is 16/6 which can't be represented by 3/8

B would be represented by 8/3 due to it's wording and the order of which the words are

However C would be 3/8 since the words say, a 3 day trips divided into 8 segments which is 3/8 unlike B which said an 8-foot piece of wood cut into 3 pieces which would be 8/3

D is just 3x8 since he consistanly saves 3 dollars for 8 weeks

I hope this makes sense and I'm sorry if this is confusing
