Answer:

-3.1

Step-by-step explanation:

[remember: (+)(+) is (+) , (+)(-) is (-) , (-)(-) is (+)]

2n + 3 = -3.2

2n = -3.2 - 3

2n = -6.2

n = -6.2/2

n = -3.1

the congruent sides of an isosceles triangle are each one unit longer than the length of the shortest side of the triangle the p

vazorg [7]

Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is

... s + (s+1) + (s+1) = 3s+2

The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so

... 3s+2 = 4s-8

... 10 = s . . . . . . . . add 8-3s to both sides

The length of the shorter side of the triange is 10 units.

Solve this system of equations by using substitution 3x + 5y = 23 y= x + 3

Iteru [2.4K]

Answer:

x=1

y=4

(1,4)

Step-by-step explanation:

TO SOLVE FOR X:

1. Substitute y=x+3 into the equation. This should look like this:

3x+5(x+3)=23

2. Use the distributive property.

3x+5x+15=23

3. Simplify:

8x+15=23

4. Subtract 15 from both sides. It should now lool like this:

8x=8

5. Divide both sides by 8.

x=1

TO SOLVE FOR Y:

1. Take x and substitute into original statement:

3(1)+5y=23

2. Simplify:

3+5y=23

3. Subtract 3 from both sides:

5y=20

4: Simplify:

y=4

CHECK ANSWER:

y=x+3

1. Substitute your answers

4=1+3

2. Simplify

4=4

3. Check for Truth. Is 4=4?

Yes. So your final answer is:

x=1

y=4

The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation I(dB)=10log[1/10], where I &a

Alexandra [31]

For this case we have the following equation:
$I(dB)= 10log(\frac{I}{I0})$
Where,
I: the intensity of a given sound
I0: the threshold of a hearing intensity
Substituting values in the given equation we have:
 $I(dB)= 10log(\frac{10^8I0}{I0})$
Rewriting the equation we have:
 $I(dB)= 10log(10^8)$
Then, by properties of logarithm we have:
 $I(dB)= 10(8)$
Finally we have:
 $I(dB)=80$
Answer:
The intensity, in decibles, [I(dB)], when I=10^8(I0) is:
D.80

5,10,12,4,6,11,12,5 find the mode

allsm [11]

Answer:

5 and 12

Step-by-step explanation:

The mode of a data set is the entry which occurs most often

Given

5, 10, 12, 4, 6, 11, 12, 5

5 and 12 both occur twice, thus there are 2 modes 5 and 12
