Answer:
9
Step-by-step explanation:
Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
Answer:
a = 100
b = 5
Step-by-step explanation:
Just plug this into the equation it shows:
R(1) = (500 + (100)(1)) (50 - (5)(1))
You must buy 4 packages of hot dogs and 5 packages of hot dog buns. The LCM of 30 and 42 is 2⋅3⋅5 ⋅7 = 210.
Answer:
Assume the pair of dice are fair; if not, all bets are off!
Color one die green (G) and the other one red (R). There are 36 possibilities in throwing one green and one red die, eg (G1, R1), (G1, R2), etc; (G2, R1), (G2, R2), etc; etc; (G6, R1), (G6, R2), etc.
In the set of possible numbers from throwing a die, there are only 3 possibilities that sum to to 4: (G1, R3), (G2, R2), (G3, R1).
So the answer is 3/36, or one-twelfth.
