An athlete eats 75 g of protein per day while training. How much protein will she eat during 21 days of training? Write your answer in kilograms.​

2/3x+6 = 8

subtract 6 from both sides

2/3x = 2

divide both sides by 2/3

x = 3

Answer:

x = 3

Step-by-step explanation:

Multiply both sides of the equation by 3

2x + 18 = 24

Move Constant to the right-hand side and change its sign

2x = 24 - 18

Subtract the numbers

2x = 6

Divide both sides of the equation by 2

x = 3

Solution

x = 3

Step-by-step explanation:

f(x) = 2x^4 − 5x^3 − 5x^2 + 20x − 12

Graph

We see that there is a zero at -2

Using synthetic division

-2      2   -5  -5   20  -12

             -4   18   -26  12

     ------------------------------  

         2   -9  13  -6     0

This gives us ( x+2) ( 2x^3 -9x^2 +13x -6)

We see that there is a zero at 2

Using synthetic division  ( 2x^3 -9x^2 +13x -6)

2       2   -9  13  -6

              4   -10  6

     ------------------------------  

         2   -5  3  0

This gives us ( x+2)   ( x-2) ( 2x^2 -5x+3)

We can factor  ( 2x^2 -5x+3)

( x+2)   ( x-2)  ( 2x -1) ( x-3)

Using the zero product property

( x+2)=0   ( x-2)=0  ( 2x -1)=0 ( x-3)=0

x=-2  x=2  x = 1/2   x=3

Answer:

21:24

Step-by-step explanation:

7:8 is your ratio

so if _:24 is equivalent, you have to figure out what 24 is divisible by to equal 8

8×3=24

so now we have to multiply 7 by 3

7×3=21

so your answer is 21:24 = 7:8

hope this helps :)

Answer: 5-4+7x+1 = [7]x+[not 2]

5-4+7x+1 = [not 7]x+[any number]

5-4+7x+1 = [7]x+[2]

Answer:

[tex] \frac{7}{9} [/tex]

Step-by-step explanation:

it seems like you're asking what the solution of each equation is put into a fraction

so, putting in 3 for g gives you

[tex]3(3) + 5 = 14[/tex]

which then goes over

[tex]((3) - 1 = 2)((3) + 6 = 9) = 18[/tex]

which gives

[tex] \frac{14}{18} [/tex]

however, this can be reduced to

[tex] \frac{7}{9} [/tex]

because both 14 and 18 can be divided by 2.

Answer:

More formally, statistical power is the probability of finding a statistically significant result, given that there really is a difference (or effect) in the population. ... So, larger sample sizes give more reliable results with greater precision and power, but they also cost more time and money.

∠2 = ∠3 ( vertically opposite angles )

= 112° = 112°

= ∠3 = ∠7 ( corresponding angles )

Answer:

2.25 and 11.25

Step-by-step explanation:

27/12=2.25 twelve is the number of hours and 27 is the total drop in price

2.25*5=11.25 because 2.25 is the drop per hour you want to multiple that by five hours.

step 1. Multiply the variable x with 13 .

step 2. Add 2 to it .

Step 1 : Subtract 2 from both sides : 13x + 2 - 2 = 41 - 2 = 39

Step 2 : Divide both the sides by 13 : 13x ÷ 13 = 39 ÷ 13 = 3

x = 3

Step 1. Subtract 3 from the variable .

Step 2. Divide the result by 5 .

[tex]Step \: 1. \: add\: 3 \: to \: both \: the \: sides : \frac{x - 3}{5} + 3 = - 1 + 3

[/tex]

Step 2 : Multiply both the sides by 5 : 5 × 1/5x = 5 × -2/5

x = -2

Answer:

3rd line

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

The value of the fraction that is equal to the number 0.16666... would be 5/30.

Given that,

Change the number 0.16666... into a fraction.

Used the concept of fraction which stated that,

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction.

Let us assume that the number 0.1666.. equal to x.

Hence,

x = 0.166666 .....  .. (i)

Multiply by 10 on both sides,

10x = 1.66666...  (ii)

Also, multiply by 100 in equation (i),

100x = 16.6666.. (iii)

Subtract equation (ii) from (ii),

100x - 10x = 15

90x = 15

x = 15/90

Simplify for the simplest form,

x = 5/30

Therefore, the value of the fraction is 5/30.
