I am pretty sure that the right answer for the first question which is being asked is the second option - <span><span>b. 3 / 7, 18 / 42
</span>What about the next one, I bet it's </span> d. 60 / 100. 3
And the last one is a. 5/8=15/24
There are 5280 ft in a mile. 55*5280=290400. So the car is travelling 290,400 ft/hour
Let the two numbers be x and y
(x+y)-18=2x
x+y-18=2x
x+y-2x=18
-x+y=18_______(1)
(x-y) -32=2y
x-y-32=2y
x-y-2y=32
x-3y=32_______(2)
from eqn (1) y=18+x____(3)
substitute eqn (3) into eqn(2)
x-3{18+x} = 32
x-54-3x=32
-2x=32+54
-2x = 86
x= -43
sub x=-43 into eqn (3)
y=18+(-43) = 18-43 = -25
Answer:
the answer is 15 i hope this correct
Y = 8(49) + 9(7) + 11
y = 466
