The answer is B. 4 3⁄8 yards. The amount of material needed for the jacket is: x = 2 5/8 yd = 2 + 5/8 = 16/8 + 5/8 = (16+5)/8 = 21/8 yd. The amount of material needed for the skirt is: y = 1 3/4 yd = 1 + 3/4 = 4/4 + 3/4 = (4+3)/4 = 7/4 yd. The total amount of material Jane needs is: x + y = 21/8 + 7/4 = 21/8 + 14/8 = (21+14)/8 = 35/8 = (32+3)/8 = 32/8 + 3/8 = 4 + 3/8 = 4 3/8 yd.
Answer:
-1 is the inverse of 16 modulo 17.
Step-by-step explanation:
To find : An inverse of 16 modulo 17 i.e.
?
Solution :
First we find the GCD of (17,16) using Euclid's algorithm,

Remainder is 1.
Which means, GCD(17,16)=1
Using back substitution we get,



i.e. -1 is the inverse of 16 modulo 17.
On comparing with 
The value of x=-1.
The answer is 2/5. Divide both the numerator and denominator by 7. :)
3+2•6/3
first you multiply the 2 and 6 on the top to get 12
so now it’s
3+12/3
now add the 12 and 3
15/3
now divide
so your answer is 5
