Answer:
x = -15
Step-by-step explanation:
Divide both sides by -2
x + 5 = -10
x = -15
Answer: x = -15
Step-by-step explanation:
-2(x + 5) = 20
-2x - 10 = 20
Add 10 to both sides
-2x = 30
Divide both sides by -2
x = -15
Which table of ordered pairs represents a proportional relationship?A x-2 4 6 у 4 16 36 B x 4 6 8 y 8 -12 -18 C x-3 -5 -7 y 5 3 1 D x-3 -6 -9 y 12 24 36
9514 1404 393
Answer:
D x-3 -6 -9 y 12 24 36
Step-by-step explanation:
The relationship is proportional when the ratio of y to x is the same for all table entries. In selection D, that ratio is ...
12/-3 = 24/-6 = 36/-9 = -4
y = 4x - 6
y = 4x + 10
What is the solution to the system?
Answer:
No Solution
Step-by-step explanation:
y = 4x - 6
y = 4x + 10
You can set them equal to each other because they both are y.
4x-6=4x+10
-6=10

If x + 15 = 30, what is the value of 2(x – 5)?
PLEASE ANSWER TODAY!!!
Answer:
Answer is 20
Step-by-step explanation:
X+15=30
30-15= 15 so that means 15+15=30
2(x-5) X is 15 so 15-5=10 then multiply by 2.
The required value of 2(x – 5) is 20 when the equation is x + 15 = 30.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows
x + 15 = 30
First, we can solve for x by subtracting 15 from both sides of the equation:
x + 15 - 15 = 30 - 15
x = 15
Next, we can substitute this value of x into 2(x – 5):
2(x – 5) = 2(15 – 5)
2(x – 5) = 2(10)
2(x – 5) = 20
Therefore, the value of 2(x – 5) is 20.

Round 94584 to the nearest hundreds
Answer:
94600
Step-by-step explanation:
A hundred has 2 zeroes. To round a number to the nearest hundreds, just look at the last 2 digits (84). If it is 5 or bigger, add 1 digit (as I did in this exercise) and so it becomes 94600.

im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]
what is the explanation to x^2 = -5x
*Answer*
x=0 or x=−5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2=−5x
Step 1: Subtract -5x from both sides.
x2−−5x=−5x−−5x
x2+5x=0
Step 2: Factor left side of equation.
x(x+5)=0
Step 3: Set factors equal to 0.
x=0 or x+5=0
x=0 or x=−5
AFTER allowing 4 % discount on the marked price of an article there is a profit of 20 % if the cost price of the article is RS 800 find marked price ? plz plz plz plz plz saw plz
Answer:
Rs. 1000Step-by-step explanation:
Let the marked price is x
Discount 4% ⇒ x - 4% = 0.96xCP = Rs. 800 Profit after discount = 20%SP = 800 + 20% = 800*1.2 = Rs. 960Now we have below equation:
0.96x = 1.2*8000.96x = 960x = 960/0.96x = 1000MP is Rs. 1000
