25% of the 9th grade belongs to more than one club.
9th grade population 180
1 club = 90
2 clubs = 33
3 or more clubs <u>= 12</u>
Students w/ clubs 135
2 clubs + 3 or more clubs = 33 + 12 = 45 ÷ 180 = 0.25 x 100% = 25%
1 club = 90 ÷ 180 = 0.50 x 100% = 50%
no club = 180 - 135 = 45 ÷ 180 = 0.25 x 100% = 25%
First isolate y by adding x to both sides in y-x=3 and getting y=x+3
Step 1: substitute x+3 for y in 3y=x+6 to get 3(x+3)=x+6
Step 2: distribute 3x+9=x+6
Step 3: subtract like terms 2x=-3
Step 4: divide x=-3/2
substitute -3/2 for x in y=x+3 to get
y=-3/2+3
y=3/2
answer: y=3/2 x=-3/2
D 5/8 i believe
because 5 up and 8 down seems right
Let f=number of field goals and a=number of points after.
a+f=38
a+3f=70
.
a+3f=70
a+ f=38
-------subtract
2f=32
.
f=16 field goals he kicked last season.
Answer:
x=1
Step-by-step explanation:
14=12x+2
subtract 2 from both sides
12=12x
divide both sides by 12 and you get x=1
