Answer:
x=-15/8
Step-by-step explanation:
Hi there!
We're given the equation -2(5x+8)=14+6x and we need to find the value of x
we do this by isolating the variable so that x is on one side, and everything else is on the other
First, we need to do the distributive property on the left, as the -2 is factored out of 5x+8 and it makes solving for x harder
-2(5x+8)=14+6x
multiply both 5x and 8 by -2
-10x-16=14+6x
add 16 to both sides to clear it from the left side (-16+16=0)
-10x-16=14+6x
+16 +16
_____________
-10x=30+6x
subtract 6x from both sides (6x-6x=0)
-10x=30+6x
-6x -6x
_____________
-16x=30
now, we do have x by itself, but we have -16 attached to it; we need the value of 1x, or x without any coefficient in the front of it
divide both sides by -16
x=30/-16
simplify (divide both sides by -2)
x=-15/8
we can leave it as an improper fraction
Hope this helps! :)
Answer:
x = 15 / 8
Step-by-step explanation:
−2(5x+8) = 14 + 6x
Simplify both sides of the equation.
−2(5x+8) = 14 +6x
(−2)(5x) + (−2)(8) = 14 +6x (Distribute)
−10x +−16 = 14 +6x
−10x −16 = 6x +14
Subtract 6x from both sides.
−10x −16 −6x = 6x + 14 −6x
−16x −16 = 14
Add 16 to both sides.
−16x −16 +16 = 14 + 16
−16x=30
Divide both sides by -16.
-16 x / - 16 = 30/-16
Simplify ( divide RHS side by - 2 )
x = 15 / 8

Answer:
2.478 million at the end of 2015
Step-by-step explanation:
Multiply the amount of population at the end of 2012 times 6%
2.1 times 0.06 = 0.126 million
So, at a constant rate, yearly, the population of Dubai increases 0.126 million
2015-2012 = 3
0.126 times 3 = 0.378 million
2.1 + 0.378 = 2.478 million

The theater sells two types of tickets: adult tickets for $15 and
child tickets for $11.
Last night, the theater sold a total of 147 tickets for a total of
$1889. How many adult tickets did the theater sell last night?
Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets

The cost to play the game is $2. The winner gets $6 for making green. Suppose 36 people play the game. How much money will the school take in from this game before giving out prize money? *
Answer:
$72
Step-by-step explanation:
I did 36 x 2. I did not subtract the -6 for the prize money because it says not to.
Answer:
$72
Step-by-step explanation:
You are trying to determine how much money the school will take in before giving out prize money. Knowing this, you can actually ignore the $6 that the winner will get because you are not worried about giving out the prize money yet. You are only worried about how much you will make before the prize money.
So, you can do simple multiplication to find the answer:
price per game * amount of people playing game = money made from games
$2 * 36 = x
$72 = x

At the beginning of spring, Bilquis planted a small sunflower in her backyard. When it was first planted, the sunflower was 10 inches tall. The sunflower then began to grow at a rate of 0.5 inches per week. How tall would the sunflower be after 8 weeks? How tall would the sunflower be after w weeks?
Height After 8 weeks: ?
Height After w weeks: ?
Answer:
Height After 8 weeks: 14 inches
Height after w weeks: y=0.5w+10
Step-by-step explanation:
The equation of the sunflower is y=0.5x+10.
Height after 8 weeks: y=0.5(8)+10
y=4+10
y=14
Height After 8 weeks: 14 inches
Height after w weeks: y=0.5w+10

Answer:
4y+x - 16 = 0
Step-by-step explanation:
Given the equaton y - 2 = 4 (x-1)
Get the slope of the line
y - 2 = 4x - 4
y = 4x - 4 + 2
y = 4x - 2
Since y = mx+b for a line
mx = 4x
m = 4
Slope of a line perpendicular M = -1/4
If the line passes through the point (-4, 5)
The equation in point slope form is expressed as y-y0 = m(x-x0)
Substitute;
y - 5 = -1/4(x-(-4))
y - 5 = -1/4(x+4)
4(y-5) = -(x+4)
4y - 20 = -x-4
4y+x-20+4 = 0
4y+x - 16 = 0
This gives the required equation
Quick questionnnnn :P
Answer:
44.
Step-by-step explanation:
Given expression: [tex]3t^2-t[/tex]
To find the value of [tex]3t^2-t[/tex] where t = 4, we need to substitute t for 4 in the expression.
After substituting, we use PEMDAS (the order of operations) to solve. This is because this problem includes multiple operations.
[tex]3(4)^2-4[/tex]
[tex]=3(16)-4[/tex]
[tex]=48-4[/tex]
[tex]=48-4=44[/tex]
[tex]\to \inft3(4)^2-4=44[/tex]
Therefore, the value of [tex]3t^2-t[/tex] is 44, when t = 4.

Find the values of x and y.
Answer:
x = 24
y = 59
Step-by-step explanation:
To solve for x, we can say that;
(5x) + (2x + 12) = 180
7x + 12 = 180
7x = 180 - 12
7x = 168
x = 168 / 7
x = 24
To solve fore y, we can say that;
(3y) + (y - 56) = 180
4y - 56 = 180
4y = 180 + 56
4y = 236
y = 236 / 4
y = 59
Hope this helps!

Find x. Round to the nearest tenth: 29 500 ft
Answer:
437.3ft
Step-by-step explanation:
last of sines
a/sin(A) = b/sin(B) = c/sin(C)
sin(90) = 1
the angle between y and 500ft side is 90-29 = 61 degrees.
so,
x/sin(61) = 500/1 = 500
x = 500 × sin(61) = 437.3ft
In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.
What is trigonometric ratio?"Trigonometric ratio is defined as in a right triangle the relation between the ratio of a sides of a triangle and the angle."
Formula used
[tex]sin\theta = \frac{opposite sides}{hypotenuse}[/tex]
[tex]cos\theta = \frac{adjacent sides}{hypotenuse}[/tex]
According to the question,
In a given right triangle ABC,
Hypotenuse [tex]=500 ft[/tex]
Opposite side [tex]= x ft[/tex]
Adjacent side [tex]= y ft[/tex]
As per the diagram drawn,
[tex]\angle BAC+ 29\° = 90\° \\\\\implies \angle BAC = 90\° -29\° \\\\\implies \angle BAC = 61\°[/tex]
Substitute the value in the above trigonometric ratio formula we get,
[tex]sin61\° = \frac{x}{500}\\\\\implies 0.8747 = \frac{x}{500}\\\\\implies x = 500 \ times 0.8747\\\\\implies x = 437.35 ft[/tex]
[tex]\implies x = 435.4 ft[/tex] (round to nearest tenth)
In trigonometric ratio [tex]cos\theta[/tex] we get,
[tex]cos61\° = \frac{y}{500}\\\\\implies 0.4848 = \frac{y}{500}\\\\\implies y= 500 \ times 0.4848\\\\\implies y = 242.2 ft[/tex]
Hence , In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.

6/50 is 12%.
Step-by-step explanation:
41% is already in percentage form, so I'm just going to leave that as it is.
1.836 has 1 whole already, so we know it's going to be more than 100%. Than we have that extra 83.6, so that would be 183.6% as a decimal.
6/50, well we divide to get 0.12, and 0.12 as a percent is 12%.
