Figure out the rest of them
Fine, I'll give you the rest.
4. d= 170/300
5. x= 600/1000
1. no, x = 15
To find the value of x in each equation, we'll use a cross-multiplication method. Here's how you can solve each equation step by step:
1. 3/4 = x/20
Cross-multiplying, we get:
3 * 20 = 4 * x
Simplifying further, we have:
60 = 4x
Divide both sides of the equation by 4:
x = 60/4
x = 15
2. 5/4 = a/36
Cross-multiplying, we get:
5 * 36 = 4 * a
Simplifying further, we have:
180 = 4a
Divide both sides of the equation by 4:
a = 180/4
a = 45
3. 18/20 = n/9
Cross-multiplying, we get:
18 * 9 = 20 * n
Simplifying further, we have:
162 = 20n
Divide both sides of the equation by 20:
n = 162/20
n = 8.1
4. 17/30 = d/300
Cross-multiplying, we get:
17 * 300 = 30 * d
Simplifying further, we have:
5100 = 30d
Divide both sides of the equation by 30:
d = 5100/30
d = 170
5. 15/25 = x/1,000
Cross-multiplying, we get:
15 * 1000 = 25 * x
Simplifying further, we have:
15000 = 25x
Divide both sides of the equation by 25:
x = 15000/25
x = 600
