He has 20 guppies?
This is what I got from the information. Unless they had eggs.
Tim counts:
11 tens:
11x10=110
and 2 ones:
110+2= 112
Tim counted 112 bounces.
Answer:
Part #1: 13/15
Part #2: 11/45
Part #3: 23/45
Step-by-step explanation:
Part #1: So add the total amount of coins: 4 + 7 + 12 + 22 = 45
Since the only coins that are at most $1 are: The $1 coins, 50 cent coins, and the 20 cent coins. That is a total of 7 + 12 + 20 = 39
39/45
13/15
Answer: 13/15
Part #2: Since the only coins that are $1 or $2: The $1 coins and the $2 coins. That is a total of 4 + 7 = 11
11/45
Answer: 11/45
Part #3: Since the only coins that are at least 50 cents: The $1 coins and the $2 coins and the 50 cent coins. That is a total of 4 + 7 + 12 = 23
23/45
Answer: 23/45
1/3x+y=10/8
Times 1/2 for both side
1/6x+1/2y=5/8
-
1/6x+1/5y=13/6
=
3/10y=-1/2
Divided 3/10 for both side
y=-5/3
1/3x+y=10/8
1/3x-5/3=10/8
1/3x=70/24
1/3x=35/12
x=35/4
x=8 3/4. As a result, the solution set is (8 3/4,-5/3). Hope it help!
Slope of line y=-1/2 x-11 is -1/2
slope of line perpendicular to this line=2
eq. of any line through (-12,3) with slope 2 is
y-3=2[x-(-12)]
y-3=2x+24
y=2x+24+3
or y=2x+27
