Exact Form:
x=-3/2
Decimal Form:
x=−1.5x
Mixed Number Form:
x=−1 1/2
Answer:
-1.5
Step-by-step explanation:
-9=-3(x+2)+5x (switching the sides of the formula can make it easier)
-3(x+2)+5x=-9
2x-6=-9
add 6 to both sides ---> 2x-6+6=-9+6
simplify ----> 2x=-3
divide both sides by 2 ---> 2x/2 = -3/2
simplify ---> x= -3/2
decimal form- -1.5
I don't get it and I have tried it multiple ways
9514 1404 393
Answer:
9350 m²
Step-by-step explanation:
There are several ways you can go at this. Here are 3 of them:
along an extension of the lower right vertical edge, divide the figure into a rectangle and a right triangle.between the upper left corner and the inside corner at lower right draw a diagonal line to divide the figure into a trapezoid and a triangle.subtract the area of the trapezoid at the right from the area of the bounding rectangle__
The relevant formulas for area are ...
rectangle: A = LW . . . . . . . . . . . length times width
trapezoid: A = (1/2)(b1 +b2)h . . . b1, b2 are the bases, h is the height
triangle: A = (1/2)bh . . . . . . . . . . . b is the base, h is the height
__
Here's what those computations look like:
1. rectangle: 60m wide by 80 m high = 4800 m².
right triangle: base 190-60 = 130 m; height = 80-10 = 70 m.
area = (1/2)(130 m)(70 m) = 4550 m²
figure area = 4800 m² +4550 m² = 9350 m² . . . . area of figure
__
2. The trapezoid has bases of 80 m and 10 m, and a height of 60 m. Its area is ...
A = (1/2)(80 m +10 m)(60 m) = 2700 m²
The triangle has a base of 190 m and a height of 80-10 = 70 m. Its area is ...
A = (1/2)(190 m)(70 m) = 6650 m²
Then the total area is 2700 m² +6650 m² = 9350 m² . . . total area
__
3. The bounding rectangle is 190 m by 80 m, so its area is ...
A = LW = (190 m)(80 m) = 15200 m²
The (negative) trapezoid at right has bases of 10 m and 80 m, and a width of 190-60 = 130 m. Its area is ...
A = (1/2)(10 m +80 m)(130 m) = 5850 m²
The area of the figure is the difference between these:
figure area = 15200 m² -5850 m² = 9350 m² . . . figure area

3n-3+10+2n=10 help plz show work
Answer:
n=3/5
Step-by-step explanation:
3n−3+10+2n=10
Step 1: Simplify both sides of the equation.
3n−3+10+2n=10
3n+−3+10+2n=10
(3n+2n)+(−3+10)=10(Combine Like Terms)
5n+7=10
5n+7=10
Step 2: Subtract 7 from both sides.
5n+7−7=10−7
5n=3
Step 3: Divide both sides by 5.
5n /5
= 3 /5
n= 3 /5
Answer:
n=3/5
Step-by-step explanation:
3n-3+10+2n=10 Combine like terms.
5n+7=10 Subtract 7 from both sides.
-7 -7
5n=3 Divide both sides by 5.
/5 /5
n=3/5

The Wilson Park Pool has 80,000 gallons of water that is being drained at a rate of 4000 gallons per day. How many days has the pool been draining if the water level is at 68,000 gallons?
Answer: 3 days
Step-by-step explanation:
1) 80,000 - 68,000 = 12,000
2) 12,000 / 4,000 = 3

The length of a rectangular fenced enclosure is 12 feet more than the width
If farmer Dan has 100 feet of fencing, find the dimensions of the rectangle with the largest perimeter that can be created using 100 feet of fencing.
Answer:
length = 31 ft
width = 19ft
largest perimeter = 100 ft
Step-by-step explanation:
Let’s say the variable is x, if you draw a rectangle, you’d lable the length as 12+x (because the length is 12 ft longer than the width) and you’d lable the width as x.
Then you’d multply both terms by 2 (and add them up):
2(12+x) + 2(x)
Once you distribute and add...
24 + 2x + 2x
24 + 4x
Then you’d set that equal to 100, since that’s the amount of fencing Dan has:
24 + 4x = 100
Subtract 24 on both sides:
4x = 76
Divide by 4 on both sides:
x = 19
Then you found the width, now to find the length, just add x to 12 (which equals to 31).
Add all the sides up and it equals to 100, which is the largest perimeter than can be created using 100 ft of fencing.
Hope this helped :)
whats the measure of the angles (SHOW YOUR WORK so I can understand)
Answer:
Angle DEB: 52
Angle ADB: 30
Angle CBE: 52
Angle BEC: 38
Step-by-step explanation:
Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.

what is the value of y in this equation. 3y - 5 = 2y
Answer:
y=5
Step-by-step explanation:
3y-5=2y
3y-2y=5
y=5
Answer:
y=5
Step-by-step explanation:
3y-5=2y
/add 5 to both sides/
3y-5+5=2y+5
simplify
3y=2y+5
subtract 2y from both sides
3y-2y=2y+5-2y
simplify
y=5
