Answer:
A) a>1
Step-by-step explanation:
2(a +8) >18
2a +16 >18
2a>18 - 16
2a>2
a>2:2
a>1
If RY + YC = RC
7x+4=10x-2
3x=6
x=2
18+18=36=RC
The value of RC is 36
Answer:
a) 3/100
Step-by-step explanation:
There are 25 total chips
P(Yellow) = 3/25
With no replacement P(Blue) = 6/24 = 1/4
Multiply 3/25* 1/4= 3/100
Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:

Answer: 13 - b., 19 - c.
