A) 290 mod 26
We subtract the largest multiple of 26 which is less than 290. The answer we get after the subtraction is the answer.
Largest multiple of 26 is 286, because 26 * 11 = 286
290 - 286 = 4.
290 mod 26 = 4.
b). 9^(-1) mod 26 = 0.111 mod 26.
0 * 26 = 0.
The largest multiple of 26 which is less than 0.111 is 0.
We subtract this from 0.111
0.111 - 0 = 0.111
9^(-1) mod 26 = 9^(-1) = 0.111
c). -15 mod 26.
Take note this is negative numbers. But same rules applies here.
The largest multiple of 26 which is less than -15 is -26.
We subtract this from -15
-15 - (-26) = -15 + 26 = 11
-15 mod 26 = 11
Answer:
the value of X is 122
Step-by-step explanation:
First, all triangle angles add up to 180 so to find the missing angle we subtract 51 and 71 from 180 and get 58
Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x
Answer: 3 gallons/minute
Step-by-step explanation:
If it is 21 gallons per 7 minutes, that is equal to 21/7. You have to make that a unit rate. 21/7 = 21 divided by 7 = 3

Answer:
n=35; q=33 coins.
Step-by-step explanation:
1) if number of nickles is 'n' and the quaters is 'q' then it is possible to write:
n+q=68 - 'she counted 68 coins...' - the 1st equation of system;
0.25q+0.05n=10 - '10$ in it' - the 2d equation of the system.
2) it is possible to make up and solve the next system of two equations:
