1a. x/20=52,5/75= 14
1b. 13/16=x/100= 81.25
1c. 18/25=1/x= 1.38
1d. 25/18=1/x= .72
I think you have a typo in 1 a.
1b. OK
1c. 1c. 18/25=1/x= 1.38888888 = 1.39
1d. OK
1a. x/20=52.5/75=14
Right.
Thanks
You're welcome.
To solve these equations, we can use cross-multiplication. Here's how to do it step-by-step:
1a. To find the value of x in the equation (x/20) = 52.5/75 = 14, we cross-multiply:
x * 75 = 20 * 14
Now we can solve for x by dividing both sides of the equation by 75:
x = (20 * 14) / 75
x = 2.96
Therefore, x = 2.96.
1b. To find the value of x in the equation 13/16 = (x/100) = 81.25, we cross-multiply:
13 * 100 = 16 * 81.25
Now we can solve for x by dividing both sides of the equation by 16:
x = (13 * 100) / 16
x = 81.25
Therefore, x = 81.25.
1c. To find the value of x in the equation 18/25 = 1/x = 1.38, we cross-multiply:
18 * x = 25 * 1.38
Now we can solve for x by dividing both sides of the equation by 18:
x = (25 * 1.38) / 18
x = 1.92
Therefore, x = 1.92.
1d. To find the value of x in the equation 25/18 = 1/x = 0.72, we cross-multiply:
25 * x = 18 * 0.72
Now we can solve for x by dividing both sides of the equation by 25:
x = (18 * 0.72) / 25
x = 0.5184
Therefore, x = 0.5184.
So, the solutions for the equations are as follows:
1a. x = 2.96
1b. x = 81.25
1c. x = 1.92
1d. x = 0.5184.
