Answer:
Remember that £ has a greater value compared to $ and vice versa.
Multiply 2/1 or 2 on both sides to get "y" by itself
![(2)\frac{1}{2}y\leq -7(2)](https://tex.z-dn.net/?f=%282%29%5Cfrac%7B1%7D%7B2%7Dy%5Cleq%20-7%282%29)
y ≤ -14
Answer:
1.ABC is equilateral triangle because all sides are equal
3.because they are the joined figure of a triangle
Here is the equation:
![-15.6 = -3.9r](https://tex.z-dn.net/?f=%20-15.6%20%3D%20-3.9r%20)
Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
Divide both sides by -3.9 to leave the variable alone:
![-15.6 \div -3.9 = -3.9r \div -3.9 \\ 4 = r](https://tex.z-dn.net/?f=%20-15.6%20%5Cdiv%20-3.9%20%20%3D%20-3.9r%20%5Cdiv%20-3.9%20%5C%5C%204%20%3D%20r%20)
r is equal to 4 → r = 4
