3 1/2 = 7/2
so than 7/2 pounds cost 1,96
than 1 pound cost x
-----------------------------------------
x = 1*1,96/(7/2) = (1,96 *2)/7 = 3,92 /7 = 0,56 so will cost $,56 so choice a. is right sure
from the graph we can see that the vertex is at h = -2 and k = - 4, we also know that the parabola runs through the point (-1 , 0)

Answer:1.2192 Meters
Step-by-step explanation:
45.2/0.2= something
we might like to make all the numbers whole numbers (1,2,3,4,5,..)
to keep fractions the same, we must multiply the top number and bottom number by the same number if we want to manipulate it
we want to move the decimal place 1 place to the right so we multiply by 10
do the same on top and bottom so 10/10 times 45.2/0.2=452/2=226
Answer + Step-by-step explanation:
GRASS method is an acronym for Given, Required, Analysis, Solution, and Statement.
<u>G</u><u>iven:</u>
- Charles has $50.00 (total)
- Charles spent 1 / 4 on a gift card (spent means subtract from total)
- Charles spent 5 / 8 on a new wallet (spent means subtract from total)
<u>R</u><u>equired:</u>
- The question asks: “How much money is leftover?” From this we know we have to find the leftover amount. Find: x = ?
<u>A</u><u>nalysis:</u>
50 (total) = x + 1/4 + 5/8 than solve for x
how much money leftover (x)
= total - spent on gif card - spent on new wallet
x = 50 - 1 / 4 - 5 / 8
<u>S</u><u>olution:</u>
x = 50 - 1/4 - 5/8
- 1/4 of 50 is 50 / 4 = 12.5
x = 50 - 12.5 - 5/8
- 5/8 of 50 is 50/8 = 6.25 <em>this is 1/8 of the price</em>
- than multiply by 5 to get 5/8, 6.25 x 5 = 31.25
x = 50 - 12.5 - 31.25
x = 6.25
<u>S</u><u>tatement:</u>
We found that the leftover amount is $6.25.
Therefore, the leftover amount of money with a starting amount of $50.00 and purchasing a gift card and new wallet is in fact $6.25.
