Answer:
Randy has to pay ![\mathbf{5b-7}](https://tex.z-dn.net/?f=%5Cmathbf%7B5b-7%7D)
Step-by-step explanation:
Cost of pear = b
Cost of apple =b-7
Randy buys pears = 4
Apple = 1
We need to find cost in terms of b
So, the equation will be:
![4b+1(b-7)\\4b+b-7\\5b-7](https://tex.z-dn.net/?f=4b%2B1%28b-7%29%5C%5C4b%2Bb-7%5C%5C5b-7)
So, Randy has to pay ![\mathbf{5b-7}](https://tex.z-dn.net/?f=%5Cmathbf%7B5b-7%7D)
Answer:
B. x = -1 or x = 4 1/3.
Step-by-step explanation:
2|3x -5| -8 =8
2|3x -5| = 16
|3x -5| = 8
The expression in the vertical lines can be positive or negative so we have 2 equations:
3x - 5 = 8 and 3x - 5 = -8
3x - 5 = 8
3x = 13
<u>x = 13/3 or 4 1/3</u>
3x - 5 = -8
3x = -8 + 5 = -3
x = -1.
Hi.
This is just messing around with exterior angles.
I say around 120 degrees, if I forgot what exterior angles were.
But <em>with quick calculation, it is probably 120 degrees</em>
