Answer: a=2/5b + 1/5c (I may have answered your question but idk if I did)
Step 1: Add -4a to both sides.
9a−2b+−4a=4a+c+−4a
5a−2b=c
Step 2: Add 2b to both sides.
5a−2b+2b=c+2b
5a=2b+c
Step 3: Divide both sides by 5.
5a/5=2b+c/5
a=2/5b+1/5c
Its simple, graph them.
For the first equation, go on the Y-Axis (the vertical one) and go to 4. Then from there go up 1, right 6.
For the second equation go on the Y-Axis (the vertical one) and plot a point at 1 (aka 0,1) Now you go up 1, right 3.
When you see an equation like y=2x+3, the 3 represents the point (0,3) as when the x is 0, y=3. Just plug the numbers in. And as for the "2x" 2 is the slope. Slope is always rise/run or up, then right. So if its 2 your slope is 2/1, rise 2, over 1. If it "-2x" is your slope then all you have to do is go down 2, right 1.
I hope this cleared up your confusion, brainliest/heart would help.
Answer:
Option C
Step-by-step explanation:
Exteriore angle property: Exterior angle equals the sum of opposite interior angles.
∠I = 77° + 56°
= 133°
11183333.3/10^7 = 1.11x10^-7.
