Answer:
1.
a = 112
b = 68
c = 68
2.
a = 127
3.
a=35
b=40
c=35
d=70
4.
a= 30
b=70
c = 30
d=70
e = 130
I'll help you with the rest later
Step-by-step explanation:
a = 112 because of allied angles rule
b and c = 68 because of angles at a point
360-112-112 ÷2
2. a = 127 because of angles on a straight line rule.
180-38-15
3. d= 70, vertically opposite angle
using angles on a straight line, 180 - 70 - 40 ÷ 2
we now have the two angles and because they are vertically opposite a and c = 35
b = 40 because of vertically opposite angles
4. a=30 because 90-70
since a=30, take 90 - 30 to get b, 70
d= 70, vertically opposite angles
e = 130 because a+b+c, vertically opposite angles
5 parts of water plus 2 parts of vinegar.
1 part of water = (2/5) parts of vinegar
= 0.40 parts of vinegar.
So Tim mixed 0.40 parts of vinegar with each (1) part of water.
Answer:
3

Step-by-step explanation:
You can solve for any variable. From the first equation, let's solve for c :

Now, replace the value of c into the other equation:

Using distributive property

However, keep in mind that this is true for:
