Answer:
If you mean 18-6x=162
18-6x=162
-6x=162-18
-6x=144
divide both sides by -6
x=-24

(2x+6)/5=4x−3
Answer:
x=7/6
Step-by-step explanation:
subtract the 4x from both sides of the equation
(2x+6)-4x=4x-3-4x
find common denominator
(2x+6)/5+(5(-4)x)/5=4x-3-4x
then combine fractions
(2x+6+5(-4)x)/5=4x-3-4x
then multiply the 5&4
(2x+6-20x)/5= 4x3-4x
combine terms
(-18x+6)/5= -3
then multiply everything by 5
-18x+6= -15
subtract the 6 from both sides
-18x= -21
divide -21 by -18
(-21)/(-18)=x
find greatest common multiple (3) and solve
x = 7/6

Answer:
231 m²₹ 4620Step-by-step explanation:
See the attached.
The path goes along the perimeter of the park and parallel to the sides, something like the picture attached.
The path is 1 m wide and the total length is:
50*3 + 30*3 = 240 mWe need to consider the dark cells points in the picture with reflects the overlaps. They are counted twice and each is 1 m x 1 m.
Subtracting the duplicated area 9 x 1 m² to get the total area of the path:
240 - 9 = 231 m²The cost of cementing is:
231*20 = 4620Which of the following expressions is equivalent to 5,710,900

The image of the point (6, -9) under a translation is (11,-4). Find the coordinates
of the image of the point (-3, -2) under the same translation.
Answer:
( - 6 , - 1 )
Step-by-step explanation:
Let's find the rule of that transformation:
1 + = 4 ⇒ = 3
9 + = 10 ⇒ = 1
Thus, the rule of given transformation is ( x + 3 , y + 1 )
So, the image of the point ( - 9 , - 2 ) is
( - 9 + 3 , - 2 + 1 ) = ( - 6 , - 1 )

Solve the following equation:
m - m-1/2 = 1 - m-2/3
Answer:
m = [tex]\frac{7}{5}[/tex]
Step-by-step explanation:
m - [tex]\frac{m-1}{2}[/tex] = 1 - [tex]\frac{m-2}{3}[/tex]
Multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions
6m - 3(m - 1) = 6 - 2(m - 2) ← distribute parenthesis on both sides
6m - 3m + 3 = 6 - 2m + 4 , that is
3m + 3 = - 2m + 10 ( add 2m to both sides )
5m + 3 = 10 ( subtract 3 from both sides )
5m = 7 ( divide both sides by 5 )
m = [tex]\frac{7}{5}[/tex]
[tex]4^{2}[/tex] =______
what is drafting committee of constitution?
Answer:
The drafting committee, chaired by B. R. Ambedkar, presented a detailed draft constitution which was published for public discussion. The draft constitution was discussed, and amendments proposed and enacted.
Step-by-step explanation:
Find two integers whose sum is -3 and product is -18
let two integers be x and y
A.T.Q
x+y= -3
or, x= -3-y(i)
and xy= -18
or,(-3-y)y= -18[by(i)]
or,- -3y-y²= -18
or,-y²= -18+3
or, -y²= -15
or, y²=15
therefore y=✓15
from (i)
x= -3-✓15
y=√15
Answer:
3 and -6
Step-by-step explanation:
1. First, let's find the factors of -18
-1 and 18, or -18 and 1-2 and 9, or -9 and 2-3 and 6, or -6 and 32. Next, we have to find which of the factors add up to -3.
[tex]-1 + 18 = 17[/tex] [tex]-18+1=-17[/tex] [tex]-2+9=7[/tex] [tex]-9+2=-7[/tex] [tex]-3+6=3[/tex] [tex]-6+3=-3[/tex]3. Great! Now that we found the factors that result in a product of -18 and a sum of -3, the factors are 3 and -6.

i now that if y or x =0
and ???????[tex]\sqrt{x+y} = \sqrt{x} +\sqrt{y}[/tex]
Answer:
Step-by-step explanation:
When you take the square root of a number, you want the number inside of the square root to be a positive sign since we can't take the square root of a negative.
So, what would make the [tex]\sqrt{x+y}[/tex] a positive?
(x+y) > 0
For each individual one, (Note: [tex]\sqrt{x+y} \neq \sqrt{x} +\sqrt{y}[/tex]
What would make [tex]\sqrt{x}[/tex] positive?
x > 0
What would make [tex]\sqrt{y}[/tex] positive?
y > 0

On a family vacation, Aaron took 1,276 digital photos. His twin sister Ashley took 4 times as many as Aaron. Write and solve an equation to find p, the number of photos that Ashley took
Answer:
Equation : 4(1,276) = p
That means that Ashely took 5104 pics.
Step-by-step explanation:
Before we come up with an equation we can solve the problem and see how we solved it. If Aaron had 1,276 pics and his sister took 4 times that, we would multiply 1,276 by 4 to get how many his sister took. We don't need to do the math, but that's how we would solve it. So to find p, or Ashely's amount of pics, it's just 1,276 times 4 = p
Equation : 4(1,276) = p
That means that Ashely took 5104 pics.

Victoria conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 1/2 degrees every 1 2/3 hours. What was the rate, in degrees per hour, that the temperature of the compound rose? Enter your answer as a whole number, proper fraction, or mixed number in simplest form.
Answer:
1/10 deg every 15 minutes x 4 = 4/10th degree in an hour (there are 4 15 minute segments in an hour)
= 2/5 degree/hr
The rate, in degrees per hour, that the temperature of the compound rose will be 1.5 degrees per hour.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Victoria conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 ¹/₂ degrees every 1 ²/₃ hours.
Convert the mixed fraction number into a fraction number. Then we have
2 ¹/₂ = 2 + 1/2 = 5/2
1 ²/₃ = 1 + 2/3 = 5/3
The rate is calculated as,
Rate = (5/2) ÷ (5/3)
Rate = (5/2) x (3/5)
Rate = 3 / 2
Rate = 1.5 degrees per hour
The rate, in degrees per hour, that the temperature of the compound rose will be 1.5 degrees per hour.
