The answer to this is -700
F ≤ 13 (add the 4 to the 9 to make 13)
<span>2y = x + 3 then x = 2y - 3
5y = x - 7 then x = 5y + 7
so
</span>2y - 3 = 5y + 7
2y - 5y = 7 + 3
-3y = 10
y = -10/3
y = -3 1/3
<span>2y = x + 3
</span>2 (-10/3) = x + 3
-20/3 - 3 =x
-29/3 = x
-9 2/3 =x
or
x = -9 2/3
solutions: x = -9 2/3 and y = -3 1/3
Answer:
£108.90
Step-by-step explanation:
![121 \times 10\% \\ = 121 \times 0.10 \\ = 108.90](https://tex.z-dn.net/?f=121%20%5Ctimes%2010%5C%25%20%5C%5C%20%20%3D%20121%20%5Ctimes%200.10%20%5C%5C%20%20%3D%20108.90)
0.41, 0.5, 3/5
convert all to decimals
0.5=0.5
0.41=0.41
3/5=0.6
