The expression 4(y + 6) would = 4y + 24
She would get £2.50
4 times 2 is 8
2 times 3 is 6
0.7 times 5 is 3.5
Add them together
Minus it from 20
It equals £2.50
The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!

Answer:
8
Step-by-step explanation:
3(y - 1) + 2x²
Let x =2 and y =1
3(1-1)+2 (2)^2
3(0) +2(4)
0+8
1. 11/(11+JG)=20/50
11+JG=27.5
JG=16.5
2. i still need some time.. is triangle RST a right-angled triangle or not?
