Nice so
remember
t=d/s
a(b+c)=ab+ac
time=distance/speed
lets say s=jamie's normal speed
speed agains wind=s-4
speed with wind=s+4
30 miles is agains wind
distance is 54 with wind
t=d/s
t=30/(s-4)
t=54/(s+4)
since they are both equal to t, set them equal to each other
30/(s-4)=54/(s+4)
multipliy both sides by (s+4)(s-4)
30(s+4)=54(s-4)
distribute
30s+120=54s-216
subtract 30s from both sides
120=24s-216
add 216 to both sides
336=24s
divide both sides by 24
14=s
answer is 14 miles per hour without wind
Answer : 32.5 g of sugar
Step-by-step explanation:
1 1/4 cup = (4+1)/4 = 5/4 cup
If 1/2 cup contains 13 g of sugar
Then 5/4 cup contains C g of sugar
C = 5/4 * 13g➗1/2 = 5*13*2g➗4 = 130g➗4 = 32.5 g of sugar
Answer : 32.5 g of sugar

In the first grid more squares are shaded than in the 2nd grid.
I believe it is the first one but I might be wrong.
