Solution: X=6

Detailed explanation:

In this problem we're asked to find "x" or the unknown.

The first step is to subtract 11x from both sides.

---\mapsto\boldsymbol{-11x+79=13}

Next, subtract 79 from both sides.

---\mapsto\boldsymbol{-11x=-66}

To finish this off, divide both sides by -11.

---\mapsto\boldsymbol{x=6}

Voila! There's our answer!

\large\green\longrightarrow \tt \large \:79 \:  -  \: 13 \:  =  \: 11x

\large\green\longrightarrow \tt \large \:66 \:  =  \: 11x

\large\green\longrightarrow \tt \large \:6 \:  =  \: x

Hence , the value of x is 6

Tcecarenko [31]
Rearrange equation.h=-16t^2-6t+110 h = 0 at the ground. divide both sides of the equation by (-2) to yield: 0 = 8t^2+3t - 55 and use quadratic equation h=<span>-b±√(b2 - 4ac)</span>                                                    2awhere a = 8, b= 3, c=-55 Substitute:  [-3 ± √(9 - 4*8*(-55))] / (16) = [6 ± √(36 + 1760)] / (16) = [6 ± √(1796)] /16 = (6 ± 42.3792)/16.  Time can only be positive for this problem...so discard negative answer. = 48.3792/16 = 3.02 seconds

Plz help...<br> 6b - 49 =2(b - 3)
wel
You always start by simplifying.
6b-49=2<span>(</span>b-3) becomes 6b-49=2b-6
From there you can group the b's together by subtracting 2b from both sides, leaving you with 4b-49=-6
Now you can get the b's alone by adding 49 (to cancel out -49) to both sides, giving you 4b=43, You're still trying to get b by itself, so what you'll do is divide both sides by 4, giving you b=10.75

If there are 42 boys and 54 girls in a room, fill out all of the possible
Setler79 [48]

Answer:

21:27 and 14:18

Step-by-step explanation:

We can solve this by using common factors

one of the common factors of 54 and 42 is 3

42/3=14

54/3=18

so one of the ratios is 14:18

another common factor is 2

42/2=21

54/2=27

so another ratio is 21:27

Find the area of the triangle below.
xenn [34]

Answer:

Well t find the area of a triangle, you need to multiple Base x height. That gives you 43.56. Now you divide by 2. So the end product will give you 21.78. Those same rules apply to every time you are finding the area of a triangle.

The equation y=x^3 + 3 is symmetric with respect to which of he following?
lianna [129]

y = x^{3} +3

Subtract 3 from both sides,

y-3=x^{3}

Let x = X and y - 3 = Y

Then,

Y = X^{3}

So, we have shifted the origin to a point (0, 3).

This is an odd function and the graph of an odd function is symmetrical about the origin.

That is, symmetrical about X = 0, Y = 0

Symmetrical about x = 0,, y - 3 = 0

Symmetrical about x = 0, y = 3.

Hence, the graph is symmetrical about the point (0, 3).
