Which equation results from adding the equations in this system?

Mathematics

Answer: 3x=3

Step-by-step explanation: Let's divide this into parts--

1. Adding the x variables: -2x+5x or 5x-2x = 3x.

2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)

3. Adding the numbers: 8-5 or -5+8 = 3.

Now just put it back into an equation: 3x + 0 = 3.

We don't need to add the 0, so the equation changes into 3x = 3.

A triangle has angles measuring 30 degrees and 90 degrees the length of the included side is 6cm. tell whether the conditions fo
Alexxx [7]
Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : <span>Two triangles are </span><span>congruent if </span>"<span>ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle</span><span>.</span>"

Josie is for a race.The ratio of the number of minutes she runs to the number of miles she runs is 24 to 3.She plans to run 10 m
saul85 [17]

Answer:

80 minutes

Step-by-step explanation:

We can solve this problem using rule of three:

The ratio of number of minutes and number of miles is 24 to 3, that is, for each 24 minutes running, she runs 3 miles.

So, if to run 3 miles she needs 24 minutes, to run 10 miles, how much time she will need:

3 miles -> 24 minutes

10 miles -> X minutes

3/10 = 24/X

X = 10 * 24 / 3 = 80 minutes.

She will take 80 minutes to run 10 miles.
