Answer:
a = d+c - r
Step-by-step explanation:
a - c = d - r
Add c to each side
a - c+c = d - r+c
a = d+c - r
A transformation like this would be a reflection across the Y access. If you flip this point about the Y access, the Y will not change but you will get the inverse of the X.
Hope this helps! :D
Answer:
Step-by-step explanation:
The principal, real, root of:
= 0.164316767
All roots:
0.164316767

0.027 is not a perfect square
Answer:
500 students.
Step-by-step explanation:
300 votes is 60%.
100%-60% is 40%
so 40% voted for the other person.
Work backwards:
x * 0.6=300
0.6x=300
x=300/0.6 which is 500.
500*0.4 is 200.
300+200 is 500.
Hope this helps :) I am terribly sorry if it is wrong or not using the number line.
2(3x-4) = 5x+6
First, expand the bracket.
6x-8=5x+6
Next, move the variables to the same side.
x-8=6
Move the -8 to the other side, change to +
x=6+8
x=14
Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.
