15 POINTS HURRY Write an expression that is equivalent to 5 3 r - 8 2

Mathematics
1 answer:
Marina86 [1]3 years ago
4 0
3 + 2 = r - 8
Add 3 + 2
5 = r - 8
Add 8 to 5 while canceling it out
13 = r
3 + 2 = 5
R =13
13 - 8 = 5
That is a true statement so an expression would be
3 + 2 = r - 8

Is x=3 a solution for the equation: 3x + 7 = 13<br> Why or why not ?
expeople1 [14]

Answer:

No.

Step-by-step explanation:

There are two different ways to do this - solve for x in the given equation or substitute the value for x and see if you get a true statement.

3x + 7 = 13 subtract 7 from both sides

3x = 6 divide by 3 on both sides

x = 2

3(3) + 7 = 13

9 + 7 = 13

16 ≠ 13

Therefore, x = 3 is not a solution for 3x + 7 = 13.

elena-s [515]

Answer:

7.92% probability that a particular death is due to a traffic accident

Step-by-step explanation:

The relative frequency approach to find the probability that a particular death is due to a traffic accident is the number of deaths due to traffic accidents divided by the total number of deaths.

We have that:

624 deaths from traffic accidents

7883 total deaths.

So

p = \frac{624}{7883} = 0.0792

7.92% probability that a particular death is due to a traffic accident
