Answer:
18
Step-by-step explanation:
3(s-5)/4 -3 = 4s- (s-3)/2
open the bracket
3s-15/4-3 =45-s-3/2
3s-15/1=42-s/2
cross multiply
2(3s-15)=42-s
3s-30=42-s
3s+s=42+30
4s=72
s=18
Answer:
s = -45/13
Step-by-step explanation:
3(s - 5)/4 - 3 = 4s - (s - 3)/2
(3s - 15)/4 - 3 = (8s - s + 3)/2
(3s - 15)/4 - 3 = (8s + 3)/2
3(s - 5)/4 - 3 = 3((8/3)s + 1)/2
3[(s - 5)/4 - 1 ] = 3((8/3)s + 1)/2
(s - 5)/4 - 1 = ((8/3)s + 1)/2
(s - 5)/4 - 4/4 = ((8/3)s + 1)/2
(s - 5 - 4)/4 = ((8/3)s + 1)/2
(s - 9)/4 =((8/3)s + 1)/2
(s - 9) = ((8/3)s + 1)(2)
s - 9 = (16/3)s + 2
s - (16/3)s = 6 + 9
(-13/3)s = 15
s = -45/13
4 (y + z); use y = 5 and z = 4
Answer:
It is 9
Step-by-step explanation:
[tex]4(y + z)[/tex]
when y is 5, z is 4
substitute:
[tex] = 4(5 + 4) \\ = 36[/tex]
Answer:
y=5 z = 4 - substitution
4 (5 + 4) = 4 (9) = 36
the product of two numbers is 21. If the first number is negaitve 3, which eaqution represents this situation and what is the second number
Answer:
-7 is the second number
Step-by-step explanation:
-3 * (-7) = 21A swimming pool holds liters of water. The pool has two drainage pipes. When the pool is completely full, the first pipe alone can empty it in minutes, and the second pipe alone can empty it in minutes. When both pipes are draining together, how long does it take them to empty the pool
Answer:Pipe 1 is emptying the pool at 600,000/200 = 3000 liters per minute.
The second pipe empties the pool at 600,000/120 =5000 litres per minute. With both pipes the pool will be emptied at 8000 litres per minute. It will therefore take 600,000/8000 = 75 minutes to empty the pool of water when both pipes are draining together.

Factor over the Reals
Answer:
(x - 2y)³(1 - x+ 2y)(1 + x - 2y)
Step-by-step explanation:
Given
(x - 2y)³ - [tex](x-2y)^{5}[/tex] ← factor out (x - 2y)³ from both terms
= (x - 2y)³(1 - (x - 2y)²) ← difference of squares which factors in general as
a² - b² = (a - b)(a + b) , then
1 - (x - 2y)²
= 1² - (x - 2y)²
= (1 - (x - 2y) )(1 + (x - 2y) )
= (1 - x + 2y)(1 + x - 2y)
Then
(x - 2y)³ - [tex](x-2y)^{5}[/tex]
= (x - 2y)³(1 - x + 2y)(1 + x - 2y) ← in factored form
3x - 8 = -2 find the value of x-6
Answer:
The answer is = -4
Step-by-step explanation:
3x - 8 = -2
3x = -2 + 8
3x = 6
x = 6 ÷3
x = 2
for x - 6
2 - 6 = -4

Answer:
its 10 trust me
Step-by-step explanation:
The coordinates of point T are (0,5). The midpoint of ST is (4, -5). Find the coordinate of point S
Answer:
(8, -15)
Step-by-step explanation:
Midpoint formula: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})[/tex]
where [tex](x_1,y_1)[/tex] is the first point (T) and [tex](x_2,y_2)[/tex] is the second point (S)
Step 1. plug in what we have so far into the midpoint formula
[tex](\frac{0+x_2}{2} ,\frac{5+y_2}{2} )[/tex]
but remember, the midpoint is (4, -5)
Step 2. solve for point (S)
The first coordinate of point (S) is the x-coordinate. And to solve for the x-coordinate, (since they're being divided by 2) multiply 2 by 4 (the x-coordinate of the midpoint)
[tex](\frac{0+8}{2},\frac{5+y_2}{2})[/tex]
... (hard to explain for the y-coordinate of point (S))
Point S = [tex](8,-15)[/tex]

5( x-2)+3x-4 = -38 solve for x
Answer:
x = -3
Step-by-step explanation:
5(x-2)+3x-4 = -38
=> 5x-10+3x-4 = -38
=> 5x+3x-10-4 = -38
=> 8x-14 = -38
=> 8x = -38+14
=> 8x = -24
=> x = -24/8
=> x = -3

Answer:
[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
If you are asking how many times does 8/3 goes into 2/3 then this means 8/3 is the dividend. The dividend is the number that is being divided by another number. This means the answer would be 8/3 divided by 2/3. I hope this makes sense.
I hope this helps :). If you have any questions let me know. Have a good day.
solve for X
1/2(10x+4)=12
Answer:
x = 2
Step-by-step explanation:
Distribute the 1/2 on the left side to each term
1/2 * 10x + 1/2 * 4 = 12
Now multiplication first before addition on the left side.
5x + 2 = 12
Subtract 2 on both sides
5x = 10
Divide by 5 on both sides
x = 2
Check work
1/2(10(2) + 4) = 12
1/2(20 + 4) = 12
1/2 * 24 = 12
24/2 = 12 = 12

Write an equation of the line that passes through the point (-1, 4) with slope 2.
Answer: y - 4 = 2 (x + 1)
Step-by-step explanation:
There are in four general forms of equations:
Slope-intercept form: y = mx + bPoint-slope form: y - y₁ = m (x - x₁)Standard form: Ax + By = CIntercept form: x/a + y/b = 1Here, we are going to use the point-slope form because the question has given us both the slope and one point.
Solve:
**Disclaimer** Since the question did not clarify, thus, I choose to use the point-slope form as it is the easiest method. However, if the question has a specified form of the equation, please tell me and I will redo it.
Given information
(x₁, y₁) = (-1, 4)
m = 2
Given expression
y - y₁ = m (x - x₁)
Substitute values into the expression
y - 4 = 2 (x + 1)
Hope this helps!! :)

Which statement is true about the given information?
A line has points B, C, D, and E. All points are equal distances from each other.
BD = One-halfBC
BC = One-halfBE
BD ≅ CE
BC ≅ BD
Mark this and return
Answer
∴ The true statement is Answer:
The true statement is BD ≅ CE ⇒ 3rd answer
Step-by-step explanation:
- There is a line contained points B , C , D , E
- All points are equal distance from each other
- That means the distance of BC equal the distance of CD and equal
the distance of DE
∴ BC = CD = DE
- That means the line id divided into 3 equal parts, each part is one
third the line
∴ BC = 1/3 BE
∴ CD = 1/3 BE
∴ DE = 1/3 BE
∵ BC = CD
∴ C is the mid-point of BD
∴ BC = 1/2 BD
∵ CD = DE
∴ D is the mid-point of DE
∴ CD = 1/2 CE
- Lets check the answers
* BD = one half BC is not true because BC = one half BD
* BC = one half BE is not true because BC = one third BE
* BD ≅ CE is true because
BD = BC + CD
CE = CD + DE
BC ≅ DE and CD is common
then BD ≅ CE
* BC ≅ BD is not true because BC is one half BD
∴ The true statement is BD ≅ CE

Solve Y^2 +9y+2=8y+58
Answer:
y²+y-56=0
56=8×7
8-7=1
(y+8)×(y-7)=0
y=7
or
y=-8
so its 7,-8
Answer:
y = -8, 7.
Step-by-step explanation:
y^2 +9y+2=8y+58
y^2 + 9y + 2 - 8y - 58 = 0
y^2 + y - 56 = 0
(y - 7)(y + 8) = 0
y = -8, 7.
