what does this mean 4x + 6y=9
12x + 18y=27

Answers

Answer 1

Answer: Infinite solutions

Step-by-step explanation:

Solve4x+6y=9for x:

4x+6y=9

4x+6y+−6y=9+−6y(Add -6y to both sides)

4x=−6y+9

4x /4 = −6y+9 /4

(Divide both sides by 4)

x= −3 /2 y+ 9 /4

Substitute

−3 /2 y+ 9 /4

for x in 12x+18y=27:

12x+18y=27

12( −3 /2 y+ 9 /4 )+18y=27

27=27(Simplify both sides of the equation)

27+−27=27+−27(Add -27 to both sides)

0=0

Answers

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]

If x + 15 = 30, what is the value of 2(x – 5)?

PLEASE ANSWER TODAY!!!

Answers

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.
