Soo lets take anna=2a sun=2a and amanda=a
2a+2a+a=45
5a=45
a=45/5
a=9
then anna and sun=18 and amanda=9
and if we compare the diff annas dollars from attachment and the work shown above = 18-15=3
soo the answer should be three
Answer:
y = -5 × 1 + 2
Step-by-step explanation:
- y = y, m = slope, x = x point given (1), b = y point given, unless a zero (2)
- Formula - y = mx + b
- Plug it in
- y = -5 × 1 + 2
Answer:
x = 2
Step-by-step explanation:
AB is given as 3(3x-1) multiply inside the parenthesis with 3
AB = 9x - 3
AC is given as 5(2x+2) multiply inside the parenthesis with 5
AC = 10x + 10
if B is midpoint of AC then AB = BC and AC = AB + BC if we write this equation using the given values
9x - 3 + 9x - 3 = 10x + 10 add like terms
18x - 6 = 10x + 10 transfer like terms to the same side of the equation
18x - 10x = 10 + 6
8x = 16 divide both sides by 8
x = 2 replace x with 2 in given expressions to find the value of each component
