Hi Kristian
a - 3b = 22
a = b - 2
We need to solve a = b -2 for a
First, we need to substitute b - 2 for a in a - 3b = 22
a - 3b = 22
b - 2 - 3b = 22
-2b - 2 = 22
-2b = 22 + 2
-2b = 24
b = 24/-2
b = -12
Now substitute -12 for b in a = b - 2
a = b -2
a= -12 - 2
a= -14
Thus, the solution is a = -14 and b = -12
The correct option is the last one (-14,-12)
If you have questions about my answer, please let me know.
Good luck!
I maybe be wrong I think it is called a Divisor?
Answer: 10 4/5
Convert the mixed numbers to improper fractions
Use the algebraic formula for addition of fractions:
a/b + c/d = (ad + bc) / bd
Reduce fractions and simplify if possible
Answer:
1. Not rhombus
2. Rhombus
3. Rhombus
Step-by-step explanation:
The little lines you see represent the size. So if you see one line on all sides, its a rhombus. If you see 1 line on one side, 2 lines on two sides, and 3 on the last side, it is not a rhombus.
Look for the lines.
