What is 5/8 divided by 1/4

Llana [10]

Answer:

Exact form: 5/2

Decimal form: 2.5

Mixed number form: 2 and 1/2

Step-by-step explanation:

when you divide a fraction you keep, change, flip

Equation: 5/8 ÷ 1/4

keep 5/8 the same

change the divide symbol into a multipulcation symbol

flip 1/4 the other way, so it's 4/1 (it's a whole number now)

then just multiply across

Equation now: 5/8 × 4/1

What is the solution of log (t minus 3) = log (17 minus 4 t)?<br> 4<br> 5<br> 15<br> 20

Tcecarenko [31]

Option A: 4 is the solution

Explanation:

The given expression is $\log (t-3)=\log (17-4 t)$

We need to determine the solution of the expression.

<u>Solution:</u>

The solution of the expression can be determined by solving the expression for t.

Let us solve the given expression.

Applying the log rule, if $\log _{b}(f(x))=\log _{b}(g(x))$ then $f(x)=g(x)$

Thus, we have;

$t-3=17-4 t$

Adding both sides of the equation by 4t, we get;

$5t-3=17$

Adding both sides of the equation by 3, we have;

$5t=20$

Dividing both sides of the equation by 5, we get;

$t=4$

Hence, the value of t is 4.

Therefore, the solution of the given expression is 4.

Thus, Option A is the correct answer.

Aaden wants to get a subscription to an online library. There are two subscription options, one of which charges a fixed 96 doll

bogdanovich [222]

Using a system of equations, the meaning of point R is given as follows:

A number of books and their cost where both subscriptions cost the same.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable. In a graph, the solution to the system is the intersection point of the two equations.

In this problem, the point R is the point in which:

3y = 96.

That is, the point in which the prices are equal, hence:

A number of books and their cost where both subscriptions cost the same.
