Answer:

(-2, -6)

Step-by-step explanation:

Given the simultaneous equation

3x-y=0 ... 1

2x+y=-10 ... 2

Add both equations to eliminate y

3x + 2x = 0 - 10

5x = -10

x = -10/5

x = -2

Substitute x = -2 into 1

3(-2)- y = 0

-6 - y = 0

-y = 0+ 6

-y = 6

y = -6

Hence the coordinate (x, y) is (-2, -6)

Answer:

-2r+8

Step-by-step explanation:

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]

Answer:

probability of rolling a number greater than 3 is 1/2

Step-by-step explanation:

all numbers on a standard number cube: 1, 2, 3, 4, 5, 6

number greater than 3:  4, 5, 6

three out of six, of one-half, are greater than three

Answer:

Three gallons will be enough to make 128 servings.

Step-by-step explanation:

In Three gallons there are 64 cups. if 5 cups makes 10 servings, that is 1/2 cup per serving. So 64 cups will make 128 servings.

25.12cm

Step-by-step explanation:

hope this helps

The required circumference of the given circle is 25.12 cm as shown figure.

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have been given data as follows:

The radius of the circle (r) = 4 cm

Circumference of the circle = 2πr

Substitute the values in the above formula and we get

Circumference of the circle = 2π(4)

Circumference of the circle = 3.14(8) = 25.12 cm

The required circumference of the given circle is 25.12 cm.

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.

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.
