Answer:
x = 5
Step-by-step explanation:
The sides are in proportion.
The proportion is 20/36
The other sides must be in the same proportion: 5x / 45
5x/45 = 20/36 You can reduce the left side by dividing top and bottom by 5
1x / 9 = 20/36 You can reduce the right side by dividing by 4
x / 9 = 5/9 at this point you should be able to see that x = 5, because the denominators are the same.
That is the answer.
However you can extend this by cross multiplying
9x = 45 Divide by 9
x = 45/9
x = 5
Answer:
simple
Step-by-step explanation:
t=b×h/2 and p= b×h
Answer:
y = 1.5x + 4
Step-by-step explanation:
Slope = (y2-y2)/(x2-x1)
= (1-4)/(-2-0) = -3/-2 = 3/2
y = (3/2)x + c
When x=0, y=4 (y-intercept is 4)
y = (3/2)x + 4
y = 1.5x + 4
