No its 20 u should know that
Answer:
b=7
Step-by-step explanation:
5a(2b – 3a) = 40
Let a=4
5*4(2b-3*4) = 40
20(2b-12) = 40
Divide each side by 20
20/20 (2b-12) = 40/20
2b-12 =2
Add 12 to each side
2b-12+12 = 2+12
2b = 14
Divide by 2
2b/2 = 14/2
b = 7

3 years ago<span>Let x = a certain number of cookies
5x = 3x + 20
5x - 3x = 20
2x = 20
x = 20/2
x = 10
John: 5x = 5(10) = 50
Jerry: 3x + 20 = 3(10) + 20 = 30 + 20 = 50
They both have 50 cookies a piece</span>
