5 0

Answer:

67\neq 0    i hope this helps!   :)

Step-by-step explanation:

given   91 = -1 + 21 + 4

lets combine like terms first   91 = -1 + 25

now add one to both sides   92 = 25

subtract 25 from both sides   67 = 0

67\neq 0 there is no solution to this problem

Marrrta [24]

Answer:

<h2>Island A, B and C has 10, 5 and 7 houses respectively.</h2>

Step-by-step explanation:

Let, the three islands A, B and C has a, b and c houses respectively.

According to the question, a + b = 15; a + c = 17; b + c = 12; a + b + c = 22.

Adding [ a + b = 15; a + c = 17]-these two, we get, a + (a + b + c) = 15 + 17 = 32\\a + 22 = 32\\a = 10.

Now, a + b = 15\\10 + b = 15\\b = 5.

a + c = 17\\10 + c = 17\\c = 7.

1 + 2 + 2^{2} + 2^{3} + 2^{x} = 1023 \\3 + 4 + 8 + 2^{x} = 1023 \\7 + 8 + 2^{x} = 1023 \\15 + 2^{x} = 1023 \\2^{x} = 1023 - 15 \\2^{x} = 1008 \ln(2^{x}) = ln(1008) \\xln(2) = ln(16 * 8 * 7) \\xln(2) = ln(2^{4} * 2^{3} * 7) \\\frac{xln(2)}{ln(2)} = \frac{4ln(2) + 2ln(3) + ln(7)}{ln(2)} \\x = 4 + \frac{2ln(3)}{ln(2)} + \frac{ln(7)}{ln(2)}

In the plane figure, only downward motion (movement leaving you relatively lower than where you were) is allowed. Find the total
bixtya [17]

<em>Plane figures</em> are shapes with <u>straight </u>sides. Considering the <em>movement</em> to be <em>lower</em> than the initial path, there are eleven (11) <u>paths</u> from A to B.

A <em>plane figure</em> is given shape with <u>straight</u> sides. And these <em>sides </em><u>connect</u> each edge of the figure one to another. Examples are triangles, quadrilaterals, polygons, etc.

A path is a <em>connection</em> or <u>link</u> between two <em>reference </em>points. This could be a <u>footpath</u> or a <u>motorable</u> path or <u>other</u> forms of the path.

Considering the given <em>plane figure</em> in the question, it can be observed that the <u>total</u> <u>number</u> of paths from A to B with respect to the given condition is eleven.
