SIMPLIFY 7/10+1/4-1/5=
Strike441 [17]

Answer:

3/4

Step-by-step explanation:

Q = \frac{7}{10} +\frac{1}{4} -\frac{1}{5}      

{the smallest common multiple of 10, 4 and 5 is 5×2×2 = 20 (denominator)}

Q =\frac{7×2}{10×2} +\frac{1×5}{4×5} -\frac{1×4}{5×4}

=\frac{14}{20} +\frac{5}{20} -\frac{4}{20}

=\frac{14+5-4}{20}

=\frac{15}{20}

=\frac{3×5}{4×5}

=\frac{3}{4}

weeeeeb [17]

Answer:

Proper Subsets = 1023

Step-by-step explanation:

GivenW= \{Hampton\ Hotels, Anytime\ Fitness, Subway, Jack\ in\ the\ Box, Supercuts, \\Jimmy\ Johns, Servpro, Denny's, Pizza\ Hut, 7-Eleven\}

Required

Determine the proper subsets

Proper Subset (P) is calculated using;

P = 2^n - 1

Where

n = number\ of\ elements

In this case;

n = 10

So:

P = 2^n - 1

P = 2^{10} - 1

P = 1024 - 1

P = 1023

Hence;

<em>Proper Subsets = 1023</em>

What is the value of x in the diagram?
PilotLPTM [1.2K]

Answer:

65

Step-by-step explanation:

They are vertical angles; so angles are congruent

*<em>Vertical angles are always congruent*</em>

<em>Congruent means equal or same.</em>

1) Since they are congruent, you form an equation.

<h2>145 = 2x + 15</h2>

2) Solve by subtracting 15 from both sides.

<h2>145 = 2x + 15</h2><h2>- 15            -15</h2><h2>----------------------</h2><h2>130 = 2x</h2>

3) Solve by dividing 2 from both sides

<h2>130/2 = 2x/2</h2>

4) Simplify

x = 65
