Answer:
(9,4)
Step-by-step explanation
You can use substitution:
plug in y=2x-14 into 3x-2y=19
3x-2(2x-14)=19
then simplify it
3x-4x+28=19
-x+28=19
-x=-9
divide everything by -1
x=9
Then plug in x=9 into the equation to find y
y=2x-14
y=2(9)-14
y=18-14
y=4
To check your answer plug x and y back into the equation
3(9)-2(4)=19 check
4=2(9)-14 check

50 students preferred science...
Explanation:
we can consider the numbers 5 and 4 in the ratio as units
now we need to know how much each unit represent
units = 5 + 4 = 9
my sample = 90 students
each unit = 90/9 = 10 students
so each unit represents 10 students
back to the ratio
who preferred science = 5
who preferred English = 4
Number of students choose Science = 5 * 10 = 50
An inequality<span> is a sentence with <, >, ≤, or ≥ as its verb. An example is 3x - 5 < 6 - 2x. To </span>solve<span> an inequality is to find all values of the variable that make the inequality true. Each of these numbers is a solution of the inequality, and the set of all such solutions is its </span>solution set<span>. Inequalities that have the same solution set are called equivalent inequalities.</span>
The answer is A when u have a little x u multiply the amoun the number u multiply it the amount of times they give for example 4 with a 5 on top is 4x4x4x4x4 multiply the 4, 5 times
