Hi there! A = 78
A + 44 = B
We can plug in the values of A and B into the equation. We then get an equation with only one variable (x), which we can solve.
1x + 76 + 44 = - 6x + 134
Collect terms.
1x + 120 = - 6x + 134
Add 6x to both sides.
7x + 120 = 134
Subtract 120 from both sides
7x = 14
Divide both sides by 7
x = 14 / 7 = 2
A = 1x + 76
Now plug in the value of x we just found
A = 2 + 76 = 78
The answer would be 1/9 since the line over it is called repeating.
Answer:
-98
Step-by-step explanation:
hope this is right
Answer:
3(2y+1)-3y=15 y=4
Step-by-step explanation:
substitute x=2y+1 into x then solve for y
The computed chi-square value is positive because the difference between the observed and expected frequencies is squared.
The formula for chi-square is the sum for all values of (observed - expected)^2 / expected.
Hope this helps!! :)
