The answer would be d , because you have to add how many of each fish to equal up to the sum of 420 . which is x y . so the first equation is x + y = 420 . then it says he bought 6 times as many parrotfish as he did angelfish so you would have to multiply x which represents angelfish by 6 . to get the second equation of y = 6x .
Answer:
x% of $900=$810
x/100×$900=$810
x=$810/9=90% required percentage is 90%.
Answer:
a- Slope-intercept form (y = + ) ::=> 1
b- Slope of Line = m = : From Equation 1
Step-by-step explanation:
a- We have following equation:
7x + 6y = 5
Here if we re-arrange for y:
6y = 5 -7x :: Compare it with y = mx + b
y = +
b-Compare y = mx + b and y = +
m= -7/6 and Slope of lines parallel to the given line is shown in the equation
