7x + 3x - 18 = 6(x + 3)
Answer:
x=9, therefore 72=72
Step-by-step explanation:
I just distributed.
Answer:
x = 9
Step-by-step explanation:
7x + 3x - 18 = 6(x + 3) ← distribute parenthesis by 6
10x - 18 = 6x + 18 ( subtract 6x from both sides )
4x - 18 = 18 ( add 18 to both sides )
4x = 36 ( divide both sides by 4 )
x = 9

How do I get the x and y intercepts to graph this equation?
Y=-1/2x-3
Answer: x intercept is (-6,0) and y intercept is (0,-3)
Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.
to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)
to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)

How do you solve -13+x=23+2x
Answer:
[tex]\boxed {x=-36}[/tex]
Step-by-step explanation:
[tex]\sf -13+x=23+2x[/tex]
[tex]\sf -13+x+13=23+2x+13[/tex]
[tex]\sf x=2x+36[/tex]
[tex]\sf x-2x=2x+36-2x[/tex]

3. In a figure a small square is cutting out from the largesquare. The area of the remaining part is 91 cm². The sum of Sides equal to 52cm.
(a). If the side of large square is x and the side of smallest square is y then find the area of the remaining part?
(b). Find the sides of the smallest square?
(c). Find the areas of the two squares?
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given that,
ABCD is a square of side x cmEFGH is a square of side y cmFurther given that,
Sum of all sides = 52 cmIt means
Perimeter of square ABCD + Perimeter of square EFGH is 52 cmWe know,
[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ Perimeter_{[square]} \: = \: 4 \times side \: }}}[/tex]
So, using this, we have
[tex]\rm :\longmapsto\:4x + 4y = 52[/tex]
[tex]\rm :\longmapsto\:4(x + y) = 52[/tex]
[tex]\rm\implies \:\boxed{\tt{ x + y = 13}} - - - - (1)[/tex]
Now, Further given that,
If square EFGH is cutting out from square ABCD, the area of remaining part is 91 square cm.
It means
[tex]\rm :\longmapsto\:Area_{[ABCD]} - Area_{[EFGH]} = 91[/tex]
We know,
[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ Area_{[square]} = 4 \times side}}}[/tex]
So, using this, we get
[tex]\rm :\longmapsto\: {x}^{2} - {y}^{2} = 91[/tex]
can be further rewritten as using algebraic Identity,
[tex]\rm :\longmapsto\:(x + y)(x - y) = 91[/tex]
[tex]\rm :\longmapsto\:13(x - y) = 91[/tex]
[tex]\red{ \bigg\{ \sf \: \because \: using \: equation \: (1) \bigg\}}[/tex]
[tex]\rm\implies \:\boxed{\tt{ x - y = 7}} - - - - (2)[/tex]
On adding equation (1) and (2), we get
[tex]\rm :\longmapsto\:2x = 13 + 7[/tex]
[tex]\rm :\longmapsto\:2x = 20[/tex]
[tex]\rm\implies \:\boxed{ \: \bf \: \: x \: = \: 10 \:cm \: \: }[/tex]
On substituting the value of x in equation (1), we have
[tex]\rm :\longmapsto\:10 + y = 13[/tex]
[tex]\rm :\longmapsto\:y = 13 - 10[/tex]
[tex]\rm\implies \:\boxed{ \: \bf \: \: y \: = \: 3 \:cm \: \: }[/tex]
So,
[tex]\rm\implies \:\boxed{Side_{[square \: EFGH]} = y \: = 3 \: cm}[/tex]
and
[tex]\rm\implies \:\boxed{Side_{[square \: ABCD]} = x \: = 10 \: cm}[/tex]
Also,
[tex]\rm :\longmapsto\:\boxed{Area_{[square \: ABCD]} = {10}^{2} = 100 \: {cm}^{2} }[/tex]
[tex]\rm :\longmapsto\:\boxed{Area_{[squareEFGH] }\: = {3}^{2} = 9 \: {cm}^{2} }[/tex]

The speed of light is 299 792 458 m / s
Which decadic units can you round to so that only one non-zero digit is produced?
Answer:
299,792,460
Step-by-step explanation:
just round to the nearest 10th
Answer:
The speed of light is exactly 299,792,458 m/s because that is how a meter is defined. A meter is defined as the distance light travels in 1/299792458 seconds in vacuum. Why was this particular number chosen? To keep the definition of meter consistent with the old standard which was an actual physical bar. The length of this bar was arbitrary though.

5/6x -4 =6
how do you solve for x?
Answer:
x=12
Step-by-step explanation:
so first you add 4 to both sides:
[tex]\frac{5}{6}[/tex]x - 4 = 6
+4 +4
= [tex]\frac{5}{6}[/tex]x = 10
now you divide 10 by [tex]\frac{5}{6}[/tex] or you can flip the fraction upside down and multiply it by 10:
[tex]\frac{6}{5}[/tex] × 10 = [tex]\frac{60}{5}[/tex] = 12
x = 12
Solve for x:
Add 4 to both sides-
5/6x - 4 = 6
+4 +4
5/6x = 10
Now divide 5/6 on both sides-
(5/6)/(5/6) = 10/(5/6)
x = 12
