A is additive equality, where -x and x adds to 0
b is distributive, where x(y+z)=xy+xz
c is multiplicative equality, where x*1=x
d is subtracting both sides by 3.
Answer:
Part A: He can use distance formula. The formula is: 
Part B: 41.63 (rounded to nearest hundredth)
Step-by-step explanation:
Plug this into the formula. First, subtract the numbers in the parentheses. Then, square them. Add those totals together. Lastly, take the square root using a calculator.
Hey there!
Let's look at this one answer at a time.
2(5 - 3) = 10 - 6 would classify as the distributive property because 2 times 5 is 10 and 2 times negative 3 equals negative 6.
-7 + (19 + 5) = (-7 + 19) + 5 would classify as an example of the associative property of equality because both sides of the equation simplify to equal the same number, 17.
11 + (6 + 8) = 11 + (28 + 6) is not a property of equality because it simplifies out to be 25 = 45 which is not true. 25 can never be equal to 45. It's no solution.
1/3 * 3 = 1 would be a great example of the inverse property of multiplication because one third is the reciprocal of three. In other words the equation could look like this: 1/3 * 3/1 = 3/3 = 1
Hope that helps! Thanks for using Brainly!
Answer:
12.5x-5(x-1)
Step-by-step explanation:
you can find the pattern easily
it simplifies as
12.5x-5x+5=7.5x+5
First multiply 2x - 5 by 3 amd will open the brackets
3(2x-5)-4=33
6x - 15 - 4 = 33
6x - 19 = 33
Take -19 to other side and its sign will be become +
6x = 33 + 19
6x = 52
x = 8.6
