X-3=5 what does x equal

Mathematics

Neporo4naja [7]3 years ago

Answer: X = 8

Step-by-step explanation: To solve for <em>x</em> in this equation, we want to get <em>x</em> by itself on the left side of the equation. Since 3 is being subtracted from <em>x</em>, to get <em>x</em> by itself, we need to add 3 to the left side of the equation. If we add 3 to the left side, we must also add 3 to the right side.

Notice that on the left side -3 and +3 cancel each other out so we're simply left with <em>x</em>. On the right side, 5 + 3 gives us 8 so we have x = 8.

We can check our answer by substituting 8 back into the original equation. So we have (8) - 3 = 5 or 5 = 5 which is a true statement so our answer is correct.

Answer:

8

Step-by-step explanation:

x-3=5

add the 3 to both sides of the equal sign

x-(3+3)=(5+3)

x=8

a school science fair has 24 projects about Earth Science in 36 projects about physical science the projects will be displayed i
Dafna1 [17]
24 =
{2}^{3}  \times 3
36 =
{2}^{2}  \times  {3}^{2}
The greatest common factor of 24 and 36 is
{2}^{2}  \times 3
Thus 12 is the greatest number of projects that can be in a row.

In a conjunction, / is true when both / and / are _____; otherwise, / is _____.
Crank
So from the onset, the answer to this question would be OPTION B.In a conjunction, / is true when both / and / are<span> TRUE</span>; otherwise, / is FALSE.

A conjunction refers to a compound statement, developed by combining two statement often through the use of the word 'AND'.  For example, the two statements, 'Roses are Red' (statement p) .... 'Violets are Blue' (statement q), can be combined to form a conjunction that reads 'Roses are Red and Violets are Blue.'  When it comes to conjunctions, it is or equivalent to the intersection of the two sets of statements (p and q → p ∩ q) which therefore means that <span>in order for the conjunction to be true, both statements must be true, otherwise, the conjunction is false.
</span>
Attached below is a truth table that seeks to further explain the point (note: ^ represent the conjunction).

1. Bob tried to answer the following question by finding the missing angle and rounding the answer to the nearest degree.
iren2701 [21]

Answer:

Part 1)

Bob's mistake was to have used the cosine instead of the sine

The measure of the missing angle is 53.13\°

Part 2) The surface area of the pyramid is 288\ cm^{2}

Step-by-step explanation:

Part 1)

Let

x----> the missing angle

we know that

In the right triangle o the figure

The sine of angle x is equal to divide the opposite side angle x to the hypotenuse of the right triangle

sin(x)=\frac{16}{20}

x=arcsin(\frac{16}{20})=53.13\°

Bob's mistake was to have used the cosine instead of the sine

Part 2) we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces

so

SA=b^{2}+4[\frac{1}{2}(b)(h)]

where

b is the length side of the square

h is the height of the triangular lateral face

In this problem

h=b/2 -------> by an 45° angle

so

b=2h

sin(45\°)=\frac{h}{6\sqrt{2}}

h=6\sqrt{2}(sin(45\°))=6\ cm

Find the value of b

b=2(6)=12\ cm

Find the surface area

SA=12^{2}+4[\frac{1}{2}(12)(6)]=288\ cm^{2}
