Answer:
90
Step-by-step explanation:
3600 / 40 = 90
so
90 x 40 = 3600
X = (Y - 5) / 6 so X is that
The denominator is the bottom portion of the fraction. Example 4/6, the 6 is the denominator. The easiest way to start out in finding the common denominator is to see what number, 8 and 14, go into equally. Example: 1/4 and 1/3, 3 and 4 both go into 12. If you multiply 4 by 3 as well as 3 by 4 you get 12 both times. Now try it with 8 and 14.
What number can 8 and 14 go into equally? (56)
8x7=56...14x4=56
Answer:
x - 5 = 9
x = 14
Step-by-step explanation:
On the left side, there are 5 -1's and 1 x. On the right side, there are 9 1's. Then we set them equal and solve
Problem:
x - 5 = 9
+ 5 + 5
x = 14
Solve 5y - x = 1 for y such that y = mx + b so we can extract the slope.
y = 1/5x + 1/5
Perpendicular lines have opposite signed reciprocal slopes.
1/5 would have an opposite signed (-) reciprocal (5) slope of -5
Now let's find b by substituting the values of y, m, and x into y = mx + b:
-1 = -5(2) + b
-1 = -10 + b
9 = b
So the equation is y = -5x + 9 or 5x + y = 9
