Answer:
a) a = 12s
Step-by-step explaination:
Answer:3/20
Step-by-step explanation:
Heads=Boy
Tails=Girl
If the first 3 students are boys, all 3 coins must be heads.
Because in 3 of these experiments, the coins all land on heads, and there are 20 experiments completed, 3 out of the 20 experiments are 3 boys; 3/20.
Step-by-step explanation:
r-5r-6s+8s-15
-4r+2s-15
= 2s-4r-15
It would be zero because x can’t be less or more in this particular situation.
Answer:
There are no solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(9x−6)=6(3x−2)+2
(2)(9x)+(2)(−6)=(6)(3x)+(6)(−2)+2(Distribute)
18x+−12=18x+−12+2
18x−12=(18x)+(−12+2)(Combine Like Terms)
18x−12=18x+−10
18x−12=18x−10
Step 2: Subtract 18x from both sides.
18x−12−18x=18x−10−18x
−12=−10
Step 3: Add 12 to both sides.
−12+12=−10+12
0=2
