q= 6
r= 7
work--
Multiply 1st column by -2:
-30q+8r=-124
5q+8r=86
Subtract 2nd column from the first column:
-35q= -210
Solve for q:
q=6
Subtract q=6 by any of the two equations, so:

2.) Write the standard number 0.00007396
in scientific notation.
A 7.396 x 10-3
B 7.396 x 10-7
C 7.396 x 10-4
D7.396 x 10-5
Answer:
7.396 × 10-5
Step-by-step explanation:
To convert 0.00007396 into scientific notation, follow these steps:
Move the decimal 5 times to right in the number so that the resulting number, m = 7.396, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -5
Write in the scientific notation form, m × 10n
= 7.396 × 10-5
Answer:D
0.00007395999999999999 7.396x10-5 7.396e-5 7.396 x 10-5

can i be brainiest...
Answer:
the answer is 14y
Step-by-step explanation:
this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.

So what we gotta do is isolate the variable by
writing it out like this
4 1/4 25 those are the numbers where those go are like this
4x - 1/4 < 25 then move on to the next line on here we write out
4x + 1/4 - 1/4 < 25 + 1/4 (The reason why i put + 1/4 is because you have to isolate the variable by doing addition as well And i always find it easier to convert the fractions to decimals then after you make that line you make the next one like this you have to add 1/4 to 4x then take it away (which is 4x) then put that to the side like this 4x ? ? then we need to find those two ?s by adding 25 and 1/4 (or o.25) which is 25.25 then we need to add that to the second answer 4x ? 25.25 when you have this you need to find out which one is bigger so it is 4x<25.25 (or 25 1/4) then we need to divide 4 and 25.25 to get 6.25 so
the answer is x < 6.25 so c is your awnser
Which of the following is an example of discrete data?
A. The distance between two cities
B. The number of siblings each student in a class has
C. Weights of sumo wrestlers
D. The length of a movie
The answer is B! Lucky guess
Answer:
this is right
Step-by-step explanation:
i just took the test and it was B!
The discrete data is option B.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive
A. Continuous data example would be the distance between two cities, which may take on any value along a continuous scale.
C. Another example of continuous data is sumo wrestler weights, which can take on any value along a continuous scale.
D. Another example of continuous data is movie duration, which can have any value along a continuous scale.
B. An example of discrete data is the number of siblings each student in a class has. The only possible values for discrete data are generally integers. The number of siblings a student has in this situation can only be a whole number, making it discrete data.

Cupid's arrow travels 45 meters in 5
seconds. What is the speed of the
flying arrow?
Answer:9
Step-by-step explanation:
45/5 =9
s=d/t
The speed of the flying arrow will be 9 meters/second.
What is the relation between speed and distance?Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.
The speed formula is speed = distance/time.
We are given that Cupid's arrow travels 45 meters in 5 seconds.
Therefore, distance = 45 meters
Time= 5 seconds.
Thus, speed = distance/time
Speed = 45/5
Speed =9
