Answer:

x+y+z=2 has no solutions. You can pick an arbitrary value for x4, and use that to calculate values for all the other variables so that all the equations will be satisfied. If you can set x4 to one of an infinity of real values, then you have an infinity of solutions

Solve the proportion. a. 4/x = 9 b. 7.5/26 = 75/p

lina2011 [118]

<u>ANSWER: </u>

The values of x and p after solving given equations are 0.445 or $\frac{4}{9}$ and 260 respectively..

<u>SOLUTION: </u>

Given, two proportions are $\frac{4}{x}$ =9 and $\frac{7.5}{26} = \frac{75}{p}$

We need to solve the given two proportions.

Let us solve the first proportion, $\frac{4}{x}$ = 9

$\frac{4}{x} = \frac{9}{1}$

On cross-multiplication, we get

4 $\times$ 1 = 9x

4 = 9x

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

x = 0.445

Now, let us solve the second proportion $\frac{7.5}{26} = \frac{75}{p}$

$\frac{\frac{75}{10}}{26}=\frac{75}{p}$

$\frac{75}{10 \times 26} = \frac{75}{p}$

$\frac{1}{260} = \frac{1}{p}$

On cross-multiplication, we get

p = 260

Hence, the values of x and p after solving given equations are 0.445 and 260 respectively.

A car factory can build 14 cars in 4 hours. <br><br> How many cars can it build in 7 hours?

inessss [21]

You can do rate. 14 divided by 4 equals 3.5. A car factory can build one car in 3.5 hours. 3.5 multiply by 7 equals 24.5.
