Soulotion to equation if y is =15 when x=2 ,find y when x=8

skelet666 [1.2K]

Answer:

The value of y for x = 8 is 60 .

Step-by-step explanation:

Given expression as :

For x = 2 , y = 15

Let the equation be written with constant k'

So, y = k x

Or, k = $\dfrac{y}{x}$

∴ k = $\dfrac{15}{2}$

<u>Now, again </u>

For x = 8

equation can be written as

y = k x

Or, y = $\dfrac{15}{2}$ × 8

Or, y = $\frac{15\times 8}{2}$

∴ y = 15 × 4

I.e y = 60

Hence The value of y for x = 8 is 60 . Answer

Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of

saw5 [17]

Answer:

Osvoldo did not meet his goal

Step-by-step explanation:

To know the percentage of carbohydrates that Osvoldo ate from grains with respect to the total, we simply have to divide the amount of carbohydrates he got with the grains by the total

55 / 220 = 0.25

then to express it as a percentage this number has to be multiplied by 100

0.25 * 100 = 25%

Osvoldo wanted to reach 30% and only got 25%

25% < 30%
