Answer:
Sophomore=S
Juniours =J
there are 22 more S than J means,
J=S+22.....................................................................1
total is 48 means
J+S=48
S+22+S=48 (put the value of J here from 1)
2S=48-22
2S=26
S=26/2
S=13
now put the value of S in 1 to find juniours
J=S+22
J=13+22
J=35
so, in the cooking class sophomores are 13 and juniors are 35.
Step-by-step explanation:
As a percent : 124%
As mixed fraction : 1 6/25
As improper fraction : 31/25
Remember, you can do anything to an equation as long as you do it to both sides
0.6x-10=1.4x-(-14)
and minusing a negative means adding
0.6x-10=1.4x+14
minus 0.6x from both sides
0.6x-0.6x-10=1.4x-0.6x+14
0-10=0.8x+14
-10=0.8x+14
minus 14 both sides
-14-10=0.8x+14-14
-24=0.8x+0
-24=0.8x
multily both sides by 10
-240=8x
divide both sides by 8
-240/8=(8x/8)
-30=(8/8)x
-30=1x
-30=x
x=-30
Answer:
The function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
Step-by-step explanation:
As given
If 30 gumballs can be purchased for 3 dollars .
i.e
30 gumballs = $3
Now find out the cost of one gumballs .
As 1 dollar = 100 cents
1 gumballs = 10 cents
Thus the cost of one gumball is 10 cents .
As d = dozen gumballs.
Let us assume that the cost for ‘d' dozen gumballs = y
Than the function becomes
y = 10d
Therefore the function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
