Answer: C is the correct answer
Step-by-step explanation:
To solve this is you have to find the price per ounce for each item by simply dividing the price by the ounces.
For the oat cereal divide $3.90 by 15
3.90/15
.26 per ounce
For the rice cereal divide $3.30 by 11
3.30/11
.30 per ounce
The oat cereal costs less per ounce since it is only .26 per ounce whereas the rice cereal is .30 per ounce.
Hope this helps!
First of all, you organize all of the info that you're given. We know that the points are (x, y). Therefore, 8 is x and 5 is y. 5/7 is your m, since m represents the slope.
x = 8
y = 5
m = 5/7
b = y-intercept, which is the missing info
Then, you put it into a multi-step equation.
The slope equation formula is y = mx + b. Now, we solve for the equation.
y = mx + b
5 = 5/7(8) + b (missing info is the y-intercept, so that's why it stays as "b")
5 = 5/7(8/1) + b (any whole number converted into fractions always have a denominator of 1)
5 = 40/7 + b At this point, since 5 as a fraction is 5/1, you need to
-40/7 -40/7 + b multiply the numerator and denominator by 7 so that
_____________ you're able to subtract 40/7 from it. So, 5 x 7 = 35 and
1 x 7 = 7, giving you the fraction of 35/7. 35/7 - 40/7 =
-5/7.
-5/7 = b
Finally, you've got all the info you need to write the equation. As a result, you just substitute the letters with the numbers:
m = 5/7
b = -5/7
y = 5/7x - 5/7
I hope I helped and that you understood my explanations! :)
Answer:
(2/3)r=30
r=45cm
Step-by-step explanation:
When trying to find a fraction of something, multiply to get your answer:
(2/3) of r = (2/3)r
The blue ribbon can be represented by both 30cm and (2/3)r cm:
(2/3)r=30
2r=90
r=45cm
Answer:
x > 8
Step-by-step explanation:
x + 5 > 11
x > 6 --- subtract 5 from both sides
x > 8 --- divide both sides by ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
