Answer:
One piece of pizza = $2.5
One candy bar = $1
Step-by-step explanation:
Call 1 pizza a, 1 candy bar b. We have:
2a + 3b = $8
=> 3(2a+3b) = 3. $8
= 6a + 9b = $24
and
6a + 5b = $20
=> (6a + 9b) - (6a + 5b) = 9b - 5b = 4b = $24 - $20 = $4
=> b = $1
=> 2a + $3 = $8
=> 2a = $5
=> a = $2.5
So one piece of pizza = $2.5, one candy bar = $1
Answer:
Step-by-step explanation:
The previous solar eclipse occured on March 7 , 1970 .
saros cycle has duration of 18 years , 11 + 1/3 days
So the earth goes 1 / 3 of its daily rotation beyond its previous location in the next solar eclipse on the earth . In order that we get solar eclipse on the same point on the earth , we shall have to wait for third solar eclipse
So total period of wait = 18 x 3 years + 11 x 3 + 1 = 54 years and 34 days
Date of next solar eclipse on the same spot = 1970 + 54 = 2024
7 th March + 34 days = April 10
likely date = April 10 , 2024 .
Gerry folded 3/8 of the pile of shirts and Molly folded 1/8 of the pile of shirts, so in total they folded 4/8 of the pile of shirts.
4 is half of 8, but it is not more than half of 8, so, together, Gerry and Molly did NOT fold more than half the shirts.
Step-by-step explanation:
to divide by a fraction is the same as to multiply by the upside-down fraction.
in your example
4 / 2/5 = 4 × 5/2 = 20/2 = 10
by the way, also a whole number is a fraction.
4 = 4/1
so, fully formal, the whole operation above looks like
(4/1) / (2/5) = (4/1) × (5/2) = (4×5) / (1×2) = 20/2 = 10/1 = 10
