The ordered pairs which is the solution of the system of Inequalities is;
x > 0 and y < 2
<h3>How to find the ordered pair of inequalities?</h3>
We are given the inequalities;
x + 2y > 4 ----(1)
3x - y < 2 -----(2)
Subtract 2y from both sides in eq 1 to get;
x > 4 - 2y ----(3)
Put 4 - 2y for x in eq 2 to get;
3(4 - 2y) - y < 2
12 - 4y - y < 2
12 - 5y < 2
Subtract 12 from both sides to get;
-5y < -10
Divide both sides by -5 to get;
y < 2
Put 2 for y in eq 3 to get;
x > 4 - 2(2)
x > 0

Mrs Kennedy is buying pencils for 315 students.
The pencils are sold in boxes of 10.
Therefore the number of pencils she needs to buy should be a multiple of 10, so that she can buy boxes of 10 pencils each.
number of students are 315 but 315 is not a multiple of 10
so we have to round off 315 to the nearest ten, that's 320.
so then she has to buy 320 pencils
number of boxes she needs - 320 / 10 = 32 boxes of pencils
she only needs pencils for 315 students so she will have 5 extra pencils
she will have to buy 32 boxes
Answer and explanation:
19.is 5th degree polynomial because the the ^ is 5 witch is a degree of 5 and there is four terms so its a polynomial
20 t will equal 49 because here is my work -16(4)^2+75(4)+5= -16(16)+300+5=-256+300+5=49
now here is some stuff to remember about 19
when ever you see something like 5x^2 its a 2nd degree monomial
when you see 5x^2+5 its a second degree binomial
when you see 6x^4+3x+2 its a 4th degree trinomial
but anything over 3 terms is a polynomial of what ever degree such as ^2 ^3 or even ^5 degree
Hope i helped you learn may i please have brainliest. Please ;)
Let x be the total number of papers that need to be delivered.
Number of papers Candy can deliver in 1 minute =x/85
Number of papers Tim can deliver in 1 minute =x/65
Time taken for both Tim and Candy all the papers together =x/ (x/85 +x/65)
= x/ (150x/ 5525)
=221/ 6 minutes
=36 minutes 50 seconds
It takes Tim and Candy 36 Minutes and 50 Seconds to deliver all the papers when they work together.
I hope this helps \(^_^)/
