XLiV represents 64 true ya false

V125BC [204]

Answer:

False

Step-by-step explanation:

Given

$XLIV = 64$

Required

True or False

The above numeral can be split as follows:

$XLIV = XL + IV$

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

$XL = -10 + 50$

$XL = 40$

In Roman numerals;

$IV = 4$

Substitute 40 for XL and 4 for IV.

$XLIV = 40 + 4$

$XLIV = 44$

Hence;

$XLIV = 64$ is false

What is -2 1/2 + 1 1/3 in fraction form?

olga nikolaevna [1]

$-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}$

Solution:

Given expression is $-2\frac{1}{2} +1\frac{1}{3}$ .

Let us first convert mixed fraction into improper fraction.

$-2\frac{1}{2} +1\frac{1}{3}=\frac{(-2\times 2) +1}{2} +\frac{(1\times 3) + 1}{3}$

$=\frac{-4 +1}{2} +\frac{3 + 1}{3}$

$=\frac{-3}{2} +\frac{4}{3}$

Take LCM for the denominators (LCM of 2, 3 = 6) and make the same.

$=\frac{-3\times3}{2\times3} +\frac{4\times2}{3\times2}$

$=\frac{-9}{6} +\frac{8}{6}$

$=\frac{-1}{6}$

$-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}$

Hence the fraction form of $-2\frac{1}{2} +1\frac{1}{3}$ is $\frac{-1}{6}$ .

Solve for n: 3n + 2n - 17 = 38

Lyrx [107]

Get all the n together so 3n+2n=5n
5n-17=38
Minus 17 from both sides
5n= 55
N= 11
