mary has y m of cloth.she used 2 m to sew a skirt.she used the remaining cloth to make 5 jackets.
(a) find the amount of material that was used to make each jacket in terms of y.
(b) if she has 17 m of cloth.how much material was used for each jacket?
a. Bal. = ym - 2m.
Amt per jacket=(ym-2m)/5 = m(y-2) / 5.
b. Amt per jacket = (17m-2m) / 5 = 15m / 5 = 3m.
To find the amount of material used to make each jacket in terms of y, we need to figure out how much material is left after Mary sews the skirt.
(a) Since Mary used 2 meters of cloth to sew a skirt, she will have y - 2 meters of cloth remaining.
To find out how much material was used for each jacket, we divide the remaining cloth by the number of jackets, which is 5. Therefore, each jacket is made with (y - 2) / 5 meters of cloth.
(b) If Mary has 17 meters of cloth, we can substitute y with 17 and calculate:
Each jacket is made with (17 - 2) / 5 meters of cloth.
Simplifying the expression, we get: 15 / 5 = 3 meters of cloth were used for each jacket.
=(17)_2/5=3
Cloth Mary has = ym
used (skirt) = 2m
Used for jacket = 5
A.) ym-2m/5 or the substitute m(y-2)/5
B.)Substitute 17 to ym
(because that's the cloth Mary has)
= (17)-2m/5
= 15m/5
= 3m
a.y-2/5
b.17-2/5
15/5
3
Just the basics
