Answer:
1/5
Step-by-step explanation:
There is five times as much water as lemon juice. So, for every part of lemon juice, there are five parts of water.
Answer:
![m\angle Y = 85\°](https://tex.z-dn.net/?f=m%5Cangle%20Y%20%3D%2085%5C%C2%B0)
Step-by-step explanation:
In Triangles YXZ and PMN
![XY \cong MP\\YZ \cong PN](https://tex.z-dn.net/?f=XY%20%5Ccong%20MP%5C%5CYZ%20%5Ccong%20PN)
Since the third side of triangle subtended by two congruent sides will always be congruent, the two triangles are congruent by SSS congruence theorem.
Therefore:![\triangle XYZ \cong \triangle MPN\\](https://tex.z-dn.net/?f=%5Ctriangle%20XYZ%20%5Ccong%20%5Ctriangle%20MPN%5C%5C)
If the measure of angle P = 85°
Since P and Y are in the same positions(as seen in the diagram) in the two triangles respectively, the measure of angle Y is also 85 degrees.
Answer:
a= -5/8
b= -4/7
c= -2/5
Step-by-step explanation:
8a + 5 = 7b + 4 =5c + 2
I'm not sure what you want with this incomplete question, but I assume it's to find the values of a, b, and c.
Therefore, to find the value of a,
8a+5=0
8a= - 5
a= -5/8
7b + 4=0
7b = - 4
b= -4/7
5c + 2=0
5c= - 2
c= -2/5
Therefore, the values of a, b, and c are -5/8, -4/7 and -2/5
