Step-by-step explanation:

abs(-4)=4

Answer:

Si recuerda, el valor absoluto de un número es el número "hecho positivo" al eliminar el signo menos si el número es negativo y simplemente dejar pasar el número si es positivo. Entonces, por ejemplo, el valor absoluto de -3 es 3 y el valor absoluto de 3 es 3.

Answer:

it's B

Step-by-step explanation:

the easiest why to tell is that, the slope intercept form y=mx+b is the form the equations are b is the y-intercept. If you look at the graph it crosses y at +16 not -16

Answer:

B. 7/16

Step-by-step explanation:

The answer to this question is the option whose value is closest to 1/2.

We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5

10/12 = 0.833

7/16 = 0.43

2/9 = 0.222

1/8 = 0.125

The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.

Answer:

For 90 students, 12 adult chaperones are required.

Step-by-step explanation:

90 (students) divided by 15 gives us a proportion to multiple the amount of adults by.

90/15 = 6

Since there are 6 times as many students as the question provided, we will multiply the amount of adults in the question by 6.

2 x 6 = 12

Answer:

the balance in the account after 20 years is $819

Step-by-step explanation:

The computation of the balance in the account after 20 years is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $500 × (1 + 2.5%)^20

= $500 × 1.025^20

= $819

Hence, the balance in the account after 20 years is $819

Answer:

[tex] \frac{1}{9} [/tex]

Step-by-step explanation:

We can multiply all exponents together

[tex] - \frac{3}{4} \times \frac{1}{3} \times 2[/tex]

-1/2

We then do

[tex] {81}^{ - 1 \div 2} [/tex]

Which is

[tex] \frac{1}{9} [/tex]

Step-by-step explanation:

= 30m² + 6√35m²

= 30m² + 6×5.91m² ---------( √35 = 5.91 )

= 30m² + 35.49m²

= 65.49m²

Answer: Jane is 10 9/30 years  old

Step-by-step explanation:

Given that Jeremy is 12 4 /5 years old

  Carl is 1 1/6 years younger than Jeremy  which is  why we would subtract giving us

=12 4/5 - 1 1/6

= 11    (24- 5)/30

= 11 19/30 years

and  Jane is 1 1 3 years younger than Carl  which is why we would subtract giving us

=11 19/30 - 1 1/3

= 10 ( 19 - 10)/ 30

=10  9/30 years

Answer:

Answer:

Step-by-step explanation:

Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.

(-3f - 4g + 9) - (2 - 6f + 5g)

-3f - 4g + 9 - 2 + 6f - 5g

+3f - 9g + 7 is your answer.

Answer:

3f−9g+7

Step-by-step explanation:

(−3f−4g+9)−(2−6f+5g)

To find the opposite of 2−6f+5g, find the opposite of each term.

−3f−4g+9−2−(−6f)−5g

The opposite of −6f is 6f.

−3f−4g+9−2+6f−5g

Subtract 2 from 9 to get 7.

−3f−4g+7+6f−5g

Combine −3f and 6f to get 3f.

3f−4g+7−5g

Combine −4g and −5g to get −9g.

3f−9g+7
