Total = 14
jhon = 2 / 14 * 20 = 2.8
mina = 5 / 14 * 20 = 7.1
tim = 7 / 14 * 20 = 10
since sweet can't be divided in decimal places so it will be 3, 7, 10
Answer:
480
Step-by-step explanation:
Original Price = o = 400
% increase in price = i = 20% = 0.20
New Price = n = ?
n = o + (o x i)
n = 400 + (400 x 0.20)
n = 400 + 80
n = 480
Hence the new price is 480
Answer:
5 gallons of gas
Step-by-step explanation:
From the above question:
If:
80 miles = 4 gallons of gas
100 miles = x gallons of gas
Cross Multiply
80 × x = 100 × 4
x = 100 × 4/80
x = 5 gallons of gas
Therefore, Jackson would use 5 gallons of gas to get to Mount Highmore.
Answer:
3/10 4/10
Step-by-step explanation:
2/5*2/2= 4/10
So you want to make one of the equations equal to one of the placeholders exg y=x+3
so we have
x+y=2 and
-2x+y=2
I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x
subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0
subsitute x=0 in x+y=2
0+y=2
y=2
x=0
y=2
