Answer:
(4.5, 8) and (8, 4.5)
Step-by-step explanation:
Given the equations
(x+y)=12.5 ... 1
X ×Y=36 .... 2
From 2, Y = 36/X
Substitute into 1
x+ 36/x = 12.5
x^2 + 36 = 12.5x
x^2 - 12.5x + 36 = 0
10x^2 - 125x + 360 = 0
2x^2 - 25x + 72 = 0
Factorize
2x^2 - 16x - 9x + 72 = 0
2x(x-8)-9(x-8) = 0
2x-9 = 0 and x-8 = 0
x = 9/2 and x = 8
when x = 9/2
Y = 36/(9/2)
Y = 36 * 2/9
Y = 8
When x = 8
Y = 36/X
Y = 36/8
Y = 4.5
Hence the solutions are (4.5, 8) and (8, 4.5)

The area of triangle QTU is 6 square units, and the area of triangle RSU is 6 square units. The dimensions in the figure below are labeled in units. What is the area of triangle STU in square units
Answer:
The area of a triangle is 1/2BH, or 1/2 times the base times the height.
If the area = 6, and B and H must both be whole numbers.
The area of the triangle ΔSTU is given by A = 12 units²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle ΔSTU be represented as A
Now , the area of triangle ΔQTU is 6 square units, and the area of triangle ΔRSU is 6 square units
So , the base of the triangle ΔSTU = 6 units
The height of the triangle ΔSTU = 4 units
So , area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
The area of triangle ΔSTU = ( 1/2 ) x 4 x 6
The area of triangle ΔSTU = 12 units²
Therefore , the value of A is 12 units²
Hence , the area of the triangle is 12 units²

Answer:
n = 4.5
Step-by-step explanation:
I think it is 4.5 because n is 3 units ahead of 1.5 on the number line:
1.5+3=4.5
Evaluate:
Σ18/1 (5n– 4) = [? ]
Basically, you are going to evaluate 5n - 4 from n = 1 to n = 18. Don't forget to add as you evaluate.
I will get you started.
Let n = 1 and then n = 2.
5(1) - 4 + 5(2) - 4 + the rest
5 - 4 + 10 - 4 + the rest
1 + 6 + the rest
7 + the rest
Just continue the pattern. You will then let n be 3, 4, 5, etc all the way to 18.

Answer:

Step-by-step explanation:
A 30 pack of Flaming Hot Cheetos cost $10.82 at
Costco. A 50 pack of Flaming Hot Cheetos cost
$17.25.
a) Which is the better buy? (You are trying to
compare the cost of a 30 pack and 50 pack of
chips. This is not possible without finding
the unit rate.)
b) What is the difference between the unit
prices? (You need to use the information
from part a to answer this question.)
Answer:
50 pack
[tex]\$0.01[/tex]
Step-by-step explanation:
Number of packs at Costco = 30
Cost of 30 packs at Costco = $10.82
Number of packs at the other place = 50
Cost of 50 packs = $17.25
Cost of one pack when 30 packs are bought
[tex]\dfrac{10.82}{30}=\$0.36[/tex]
Cost of one pack when 50 packs are bought
[tex]\dfrac{17.25}{50}=\$0.35[/tex]
It is better to buy the 50 pack.
Difference in the unit prices = [tex]0.36-0.35=\$0.01[/tex].

What is the prime factorization of 110?
Answer:
The prime factors of 110 are 2, 5, and 11.
Step-by-step explanation:
First, 110 = 2 * 55
Next, 55 = 5 * 11
Thus, the prime factors of 110 are {2, 5, 11}
Answer:
2 x 5 x 11 = 110.
Step-by-step explanation:
The prime factors of 110 are 2, 5, and 11.
-Factors of 110: 1, 2, 5, 10, 11, 22, 55 and 110
-Prime Factorization of 110: 110 = 2 × 5 × 11
1 × 110 = 110
2 × 55 = 110
5 × 22 = 110
10 × 11 = 110
11 × 10 = 110
22 × 5 = 110
55 × 2 = 110
110 × 1 = 110

HELP ASAPPPPP PLZZZZ Question in pic!!!!!
Step-by-step explanation:
Given
5y + 68 = 3y + 96 (vertically opposite angles) and
3x + 18 = 5x + 2 (vertically opposite angles)
Now solve for x.
[tex]3x + 18 = 5x + 2 \\ 3x + 18 - 5x = 2 \\ - 2x + 18 = 2 \\ - 2x = 2 - 18 \\ - 2x = - 16 \\ x = - 16 \div - 2 \\ = 8[/tex]
Now Solve for y.
[tex]5y + 68 = 3y + 96 \\ 5y + 68 - 3y = 96 \\ 2y + 68 = 96 \\ 2y = 96 - 68 \\ 2y = 28 \\ y = 14[/tex]
