Answer:
x = 24 + y
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
Perpendicular lines have gradients that multiply to give -1
So, the gradient of the line we need is -1/0.2 = -5
If we have the gradient and a point in the line, we can work out the equation using the formula:
y - y1 = m(x - x1)
where m = gradient, y1 = y-coordinate and x1 = x-coordinate of the same point
So, we substitute in our values, and we get:
y - -8 = -5(x - -7)
y+8 = -5x-35
y = -5x-43

Answer:
B 126, 126+7 equals 18 so thats the answer
Glens equation:
common factor between our denominators is 30 so multiply 3/10 by 3 to get 9/30 and 1/3 by 10 to get 10/30 and multiply 1/2 by 15 to get 15/30
(3 9/30 + 4 1/30) = 7 10/30
7 10/30 + 2 15/30 = 9 25/30
simply 25/30 by dividing by 5 to get 5/6
glens sum: 9 5/6 or 9 25/30
anas equation:
common factor between our denominators here is also 30 so 1/3 times 10 is 10/30 and 3/10 times 3 is 9/30 and 1/10 times 3 is 3/30
(4 10/30 + 3 9/30) = 7 19/30
7 19/30 + 2 3/30 = 9 22/30
simplify by dividing by 2 to get 11/15
anas sum: 9 11/15 or 9 22/30
now add 9 25/30 and 9 22/30 to get the total sum - 18 47/30 or 19 17/30
