Hello.
The answer is: 17.25
To get the answer
Hockey cards: x= 6y
baseball cards: x + y = 525
if u add them both you get 75 and 450 then times by 6
= 450 * .03+ 75 * .05
Have a nice day
Answer:
a. fly = 5.7
b. fly = 7.5
Step-by-step explanation:
a.
hoist/fly = 1 / 1.9
The new hoist is 3. To get this you have to multiply 1 by 3. That means you have to multiply 1.9 by 3 too.
1.9 * 3 = 5.7
b.
hoist/fly = 3/5 (this is the new ratio)
4.5 / 3 = 1.5
5 * 1.5 = 7.5
The last number will either be 5 or 0. For example 15, or 20.
Answer:
can u add a picture?
Step-by-step explanation:
"Will is twice as old as Jill."
Jill's age . . . . . J
Will's age . . . . 2J .
"Three years ago . . .
Jill's age then . . . . . J - 3
Will's age then . . . . 2J - 3
". . . Jill's age then was 2/5 of Will's age then."
J - 3 = (2/5) (2J - 3)
Multiply
each side by 5 : 5J - 15 = 2 (2J - 3)
Divide
each side by 2 : 2.5 J - 7.5 = 2J - 3
Subtract 2J
from each side: 0.5 J - 7.5 = -3
Add 7.5
to each side: 0.5 J = 4.5
Multiply
each side by 2 : J = 9
Jill is 9 y.o. now.
Will is 18 y.o. now.
