Kate and kelvin played a shooting game. Kevin got 52 points which was 54 points less than 2 times that of kates points. How many

Hunter-Best [27]

Answer: 53 points

Step-by-step explanation:

Let the number of points gotten by Kate be represented by x.

Since we are given the information that Kevin got 52 points which was 54 points less than 2 times that of kates points. This can be formed into an equation as:

(2 × x) - 54 = 52

2x - 54 = 52

2x = 52 + 54

2x = 106

x = 106/2

x = 53

Kate got 53 points

What is 3 1/8 - 1/2

irina1246 [14]

Answer:

$\frac{21}{8}$

Step-by-step explanation:

Given: $3\frac{1}{8} - \frac{1}{2}$

Let's changed that mixed number to an improper fraction. Now we get:

$\frac{25}{8} - \frac{1}{2}$

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

$\frac{25}{8} - \frac{4}{8}$

We can use $\frac{4}{8}$ because it is equal to $\frac{1}{2}$ . Now, all we need to do is subtract the numerators:

$\frac{25}{8} - \frac{4}{8}=\frac{21}{8}$
