The answer is 77 but i don't see it as an option here ;/
Since there are four suits, with each having a 4 and 5, we have 2+2+2+2=2*4=8
Answer:
x = 0.667 and y = -0.6
Step-by-step explanation:
Given that,
6x + 5y = 1 ....(1)
6x - 5y = 7 ...(2)
We need to solve the above equations.
Subtract equations (1) and (2)
6x + 5y -(6x - 5y) = 1-7
6x+5y-6x+5y = -6
10y=-6
y = -0.6
Put the value of y in equation (1).
6x + 5(-0.6) = 1
6x = 1-5(-0.6)
6x = 4
x = 0.667
Hence, first step is to subtract equation (1) and (2) then put the value of y in equation (1).
In the linear equation ; "y= mx + b" , "m" = the slope of the line , and "b" = the y-intercept . So the y-intercept is the value of y at the point where the line crosses the y axis .
"Z" would equal 8. 7 X 8 = 56
