Elan Coil [88]2 years ago
4 0

Answer:

  • Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles

Step-by-step explanation:

<u>Distance per person:</u>

  • Jenny - x, Keith - y, Joanna - z

<u>Equation as per given:</u>

  • y = x + 3
  • z = 2y = 2(x + 3)
  • x + y + z = 16

<u>Substitute and solve for x:</u>

  • x + (x + 3) + 2(x + 3) = 16
  • 2x + 3 + 2x + 6 = 16
  • 4x = 7
  • x = 7/4 = 1.75

Then

  • y = 1.75 + 3 = 4.75
  • z = 4.75*2 = 9.5

Which of the following sets of numbers could represent the three sides of a triangle?
san4es73 [151]

Answer:

To enable a set of three numbers to represent three sides of a triangle, sum of smaller two numbers must be greater than the largest number. Hence, only C can represent a triangle.

⚪ The sum of the measures of the interior angles of a triangle in Euclidean space is always 180 degrees

<em><u>The answer is none</u></em>

Find the value of x <br><br> A. 5 square root 2/2<br> B 5<br> C 10<br> D 10 square root 2
grandymaker [24]

Answer:

The answer is C

Step-by-step explanation:

That side with the 5 is equal to 7.071067812.... (irrational number)

To get x you need to use the equation a^2 + b^2 = c^2

A^2 and B^2 will both be the same thing. The red line indicates they are the exact same length.

7.071037812.... ^2 is 50

Now your equation would be 50+50= c^2 (which is the same as x^2)

100= c^2 is simplified by finding the square root of 100.

Your answer is 10 for side X because the square root of 100 is 10.

This problem was solved using the Pythagorean Theorem.

49 ÷ 43 = sorry guys about the bad question its actually 4 to the 9th power divided by 4 to the third power
zalisa [80]
First of all, if you look at the question, you will notice that the two numbers involved are the same (that is; 4 and 4). However, there are two ways to solve this. But the easiest way is by using indices. In indices, whenever you are multiplying two numbers that are the same, the powers are added. And whenever you are dividing two numbers that are the same, the powers are subtracted. This is due to the fact that in indices, addition is related to multiplication and subtraction is related to division. An example is;
A⁵ × A³ = A⁽⁵⁺³⁾ =A⁸
A⁵ ÷ A³ = A⁽⁵⁻³⁾ =A²
  Anyway, over to the question now;
4⁹÷4³
4⁽⁹⁻³⁾
4⁽⁶⁾
  Therefore; 4×4×4×4×4×4=4096
So the answer is 4096. However, if you calculate 4⁹÷4³ on a calculator, you will still get 4096. Hope i helped. Have a nice day

Solve each system substitution 6x - 12y=24 And -x - 6y=4
almond37 [142]
6x-12y=24
x=-6y-4
6(-6y-4)-12y=24
-36y-24-12y=24
-48y=48
y=-1
6x-12(-1)=24
6x+12=24
6x=12
x=2

6(2)-12(-1)=24
12+12=24
 24=24 true
and
-(2)-6(-1)=4
-2+ 6=4
4=4 true
