Answer:
7/25
Step-by-step explanation:
Probability = # of favorable outcomes / # of possible outcomes
Favorable outcomes = # of blue and yellow marbles
There are 3 yellow marbles and 4 blue marbles
There are 7 blue and yellow marbles so the favorable outcome is 7
Possible outcomes = total number of marbles
12 + 3 + 6 + 4 = 25
There are a total of 25 marbles
So possible outcomes = 25
If probability= favorable outcomes / possible outcomes then the probability of pulling a blue or yellow marble is 7/25
Answer:
There are 21 skateboards and bicycles in the shop.
A bicycle has two wheels, and a skateboard has four wheels
54 new wheels are needed
Number of bicycles = 15
Number of skateboards = 6
Step-by-step explanation:
Number of bicycles and skateboards = 21
Number of new wheels ordered = 54
Number of wheels in a bicycle = 2
Number of wheels in a skateboard = 4
Number of skateboards and bicycles in shop?
Let number of bicycles = b
Number of skateboards = s
b + s = 21 - - - (1)
(2*b) + (4*s) = 54
2b + 4s = 54 - - - - - - (2)
From (1)
b = 21 - s
2(21 - s) + 4s = 54
42 - 2s + 4s = 54
42 + 2s = 54
2s = 54 - 42
2s = 12
s = 6
From : b = 21 - s
b = 21 - 6
b = 15
Number of bicycles = 15
Number of skateboards = 6
Answer:
c=-5
Step-by-step explanation:
2c-3=12-2c+7c
2c-3=12+5c
2c-5c-3=12
-3c-3=12
-3c=12+3
-3c=15
c=15/-3
c=-5
