What is -3/4 + 3/8? Thanks.

AURORKA [14]

Answer:

$- \frac{3}{8}$

Step-by-step explanation:

First, we change both denominators to the LCM (lowest common multiple) which is 8.

$- \frac{3}{4} + \frac{3}{8} = - \frac{6}{8} + \frac{3}{8}$

Since the denominators are the same, we can add the numerators.

$\frac{ - 6 + 3}{8}$

$\frac{ - 3}{8}$

or it can be written as

$- \frac{3}{8}$

A small theater with 200 seats sells two kinds of tickets for a performance. Premium tickets sell for $20 each and Standard tick

KATRIN_1 [288]

P + s = 200......p = 200 - s
20p + 15s = 3400

20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold

p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold

Triangle LMN is positioned inside rectangle LKPN as shown in the diagram. Which is the area of △LMN?

Sati [7]

Step-by-step explanation:

The formula of a triangle is A=½bh

Base=6.5

Height=4.8(since the height if the triangle and the width of the rectangle are same)

A=½(6.5)(4.8)

A=½(31.2)

$a = \frac{31.2}{2}$

A=15.6

Therefore, the area of the triangle LMN is 15.6

I hope this helps.
