Write a real-world problem that can be modeled by the equation 1.25x=0.75x+50

1 answer:

7 0

We have such equation
1.25x=0.75x+50 /-0.75x (subtract 0.75 both sides)
1.25x-0.75x=0.75x-0.75x+50
0.5x=50 /*2 (multiply both sides times 2)
0.5x*2=50*2
x=100 - its the answer

Answer:

x=36

Step-by-step explanation:

So, lets go over what we know:

16 is equal to 4/9ths of x.

As a equation, this looks like:

$16 = \frac{4}{9}x$

We can begin to solve for x by multiplying both sides by the denominator, 9, which gets us:

$16*9 = 4x$

$144 = 4x$

Then we can divide by the coefficent of x, which is 4, to get our answer:

$\frac{144}{4} = x$

$36=x$

This is our answer! Hope this helps! :3

2) For which value of P and W is P + W a rational number? P = 1/(sqrt(3)) And W = 1/(sqrt(6)) 2) P = 1/(sqrt(4)) and w = 1/(sqrt

Answer:

P = 1/(sqrt(4)) and w = 1/(sqrt(9))

Step-by-step explanation:

Only the roots of perfect squares are rational numbers. 2, 3, 6, and 10 are not perfect squares, so their roots are irrational. Both 4 and 9 are perfect squares, so their roots are rational. The sum of rational numbers is a rational number.

$\dfrac{1}{\sqrt{4}}+\dfrac{1}{\sqrt{9}}=\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{5}{6}\quad\text{a rational number}$
