Answer:
Alex will need 14 bags
Step-by-step explanation:
B= 4(2x+7)+3(2x+7)
and
2x+7=2
First, we should solve the second equation to obtain x:
2x+7=2
2x=2-7
x= -5/2
Then, we use this answer to calculate B:
B=4(2(-5/2)+7)+3(2)
B=4(-5+7)+6
B=4(2)+6
B=8+6
B=14
Alex will need 14 bags
Answer: 26/52 or 0.5 or 50%
Step-By-Step:
So since there are 52 cards in a deck and half of them are red which does include the red ace that means you have 26/52 probability. The red aces are already including in this half of the deck and sense it is an or statement we do not need to add it back into the probability.
Answer:
38.88
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
15 - 23 = -8
To check, add 23.
-8 + 23 = 15
15 = 15.
