Step-by-step explanation:
1 pound is equal to 16 oz.
So 98 pounds is equal to 1568 oz.
Answer:
cups
Step-by-step explanation:
We are told that a recipe calls for one half cup of ingredient A for every 1 and two thirds cups of ingredient B.
To find the number of cups of ingredient B we will use proportions.
![1\frac{2}{3}=\frac{5}{3}](https://tex.z-dn.net/?f=1%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B5%7D%7B3%7D)
![\frac{\text{Number of cups of ingredient A}}{\text{Number of cups of ingredient B}} =\frac{\frac{1}{2}}{\frac{5}{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20A%7D%7D%7B%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20B%7D%7D%20%3D%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7D%7D%7B%5Cfrac%7B5%7D%7B3%7D%7D)
Now let us substitute our amount of Ingredient A =4 in our proportions.
![\frac{4}{\text{Number of cups of ingredient B}} =\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20B%7D%7D%20%3D%5Cfrac%7B3%7D%7B10%7D)
![\frac{\text{Number of cups of ingredient B}}{4}=\frac{10}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20B%7D%7D%7B4%7D%3D%5Cfrac%7B10%7D%7B3%7D)
Multiplying both sides of our equation by 4.
![4*\frac{\text{Number of cups of ingredient B}}{4}=4*\frac{10}{3}](https://tex.z-dn.net/?f=4%2A%5Cfrac%7B%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20B%7D%7D%7B4%7D%3D4%2A%5Cfrac%7B10%7D%7B3%7D)
![\text{Number of cups of ingredient B}=\frac{40}{3}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20B%7D%3D%5Cfrac%7B40%7D%7B3%7D)
![\text{Number of cups of ingredient B}=13\frac{1}{3}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20cups%20of%20ingredient%20B%7D%3D13%5Cfrac%7B1%7D%7B3%7D)
Therefore, we need
cups of ingredient B to make our recipe.
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.

Answer:
-1/7=n
Step-by-step explanation:
We can use cross products to solve
5 7
-------- = ------
n+3 4
5*4 = 7*(n+3)
20 = 7*(n+3)
Distribute
20 = 7n+21
subtract 21 from each side
20-21 = 7n+21-21
-1 = 7n
Divide each side by 7
-1/7 = 7n/7
-1/7=n
