Answer:
5 bags
Step-by-step explanation:
Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags
The above provides 10pounds of potting soil already
Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil
We know that 1 bag contains 5/8 pounds of potting soil
x bags contain 3 pounds of potting soil
On cross multiplication we get
![\frac{5x}{8}=3](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B8%7D%3D3)
x =
since x is an integer x = 5 bags
Note that an extra amount of soil will be remained unused
Answer:
x = -6
Step-by-step explanation:
The triangle in the picture is an isoceles triangle in which the measure of top vertex angle is given and one of the base angles is also given.
According to angle sum property of triangle , sum of measure of all the angles of traingle is 180°. Also, in isosceles triangle , the base angles are always equal to each other .
So,
![34 + (x + 79) + (x + 79) = 180](https://tex.z-dn.net/?f=34%20%2B%20%28x%20%2B%2079%29%20%2B%20%28x%20%2B%2079%29%20%3D%20180)
![= > 2x + 158 + 34 = 180](https://tex.z-dn.net/?f=%20%3D%20%20%3E%202x%20%2B%20158%20%2B%2034%20%3D%20180)
![= > 2x +192 = 180](https://tex.z-dn.net/?f=%20%3D%20%20%3E%202x%20%2B192%20%3D%20180)
![= > 2x = 18 0 - 192 = - 12](https://tex.z-dn.net/?f=%20%3D%20%20%3E%202x%20%3D%2018%200%20-%20192%20%3D%20%20-%2012)
![= > x = \frac{12}{ - 2} = - 6](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20x%20%3D%20%5Cfrac%7B12%7D%7B%20-%202%7D%20%20%3D%20%20-%206)
