25+10+10+10+1+1= 57
165
25 as 10+10 is 20 plus 5 is 25
So, laying out the question in traditional format: 2 + -25 + 22 + -9 = ? Starting from the left, 2 + -25 = -23 -23 + 22 = -1 -1 + -9 = -10 The solution is -10.
25 + 10 = 35
-Y + 10 = 25; first subtract 10 from each side of eq: -Y + 10 - 10 = 25 -10; and simplify:-Y = 25 - 10 = 15; last, multiply each side by -1: -1*(-Y) = -1*15 --> Y = -15
25 + 15 + 21 + 10 + 11 = 82
10 plus 25 divided by 5 is 15
10+(-25)=(-15)
25 + 2*10 + 1 = 46 cents
25/20 or 1 and 1/4
It is: 25+10+5 = 40
The answer is 43. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
