10. Write a word problem for this equation: n ($25) = $125

Andrei [34K]

Answer:

The word problem is "How many $25 are there in $125?"

Step-by-step explanation:

Given

$n(\$25) = \$125$

Required

Write a word problem for the expression

We start by solving the given equation

$n(\$25) = \$125$

Divide both sides by $25

$\frac{n(\$25)}{\$25} = \frac{\$125}{\$25}$

$n = \frac{\$125}{\$25}$

$n = 5$

This implies that there are 5, $25 in $125

Hence; The word problem is "How many $25 are there in $125?"

Solve for q. √3q + 2 = √5

34kurt

Answer:

$q = 0.0186$

Step-by-step explanation:

To solve for q, we initially place everything with the term q to one side of the equality, and everything without the term q to the other side of the equality.

$\sqrt{3q} + 2 = \sqrt{5}$

$\sqrt{3q} = \sqrt{5} - 2$

We find the square of both sides of the equation. So

$(\sqrt{3q})^{2} = (\sqrt{5} - 2)^{2}$

$3q = 0.0557$

$q = \frac{0.0557}{3}$

$q = 0.0186$

In the equation 9 more than 3 times a number is -6, what does a number equal

atroni [7]

So 9 more than 3 times a number, would be:
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5

your welcome!!!! :)
