Find the missing number of each unit rate. 155 = ?1 246 = ?1<br><br>worth 15 points!!!
alexgriva [62]

This is an incomplete question, the correct question is given below.

Find the missing number of each unit rate \frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1}

Answer : The missing number of each unit rate of \frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1} are, 3 and 4 respectively.

Step-by-step explanation :

As we know that a unit rate is a rate in which 1 is present in denominator.

Or we can say that,

A unit rate is also called a single unit rate that means it will compare 1 unit of some quantity to a different units of a different quantity.

As we are given that that unit rates:

\frac{15}{5}=\frac{?}{1} and \frac{24}{6}=\frac{?}{1}

Now we have to determine the missing number of each unit rates.

So, we can write the given expression as:

\frac{15}{5}=\frac{?}{1}

When are dividing 15 by 5, we get:

\frac{15}{5}=\frac{3}{1}

Thus, the missing number is, 3

And

\frac{24}{6}=\frac{?}{1}

When are dividing 24 by 6, we get:

\frac{24}{6}=\frac{4}{1}

Thus, the missing number is, 4

How do you solve for x?<br> 1953=x(x+1)/2
Alexxx [7]
*1953 = x(x + 1) /2 2* 1953 = x (x + 1) 3906 = x^2 + x x^2 + x - 3906 = 0 (X + 63) (x - 62) =0 X + 63 = 0. ^ x - 62 = 0 X = -63 ^ x = 62 :)
