I need help -x + 5y = 14, x + 3y = 18 solve by substitution
Answers
Answer:
x=6,y=4 equation form
or
(6,4) point form
Step-by-step explanation:
Step-by-Step Explanation:
=> -x + 5y = 14 (Eq. 1)
=> x + 3y = 18 (Eq. 2)
From Eq. 2,
=> x = 18 - 3y (Eq. 3)
Substitute value of ‘x’ from Eq. 3 in 1 :-
-x + 5y = 14
-(18 - 3y) + 5y = 14
-18 + 3y + 5y = 14
8y = 14 + 18 = 32
=> y = 32/8 = 4
Therefore, y = 4
Substitute value of ‘y’ in Eq. 3 :-
x = 18 - 3y
x = 18 - 3(4)
x = 18 - 12
=> x = 6
Therefore, x = 6
Kylie is 5 years older than Ellie and triple Jon's age. If the sum of their ages is 65 , how old is Jon?
PLS HELP! 20 POINT FOR THE RIGHT ANSWER!
Answers
Answer:
Jon is 10 years old
Step-by-step explanation:
This is solved using linear equations. We use the information given to make equations.
Let's use K for Kylie, E for Ellie, and J for Jon:
K = E + 5
K = J x 3
Now, we rearrange these equations so that K is on the right side:
E = K - 5
J = K/3
Now, with only one variable, we make a new equation:
K + (K - 5) + (K/3) = 65
Simplify:
2K - 5 + K/3 = 65
Isolate k:
[tex]\frac{7k}{3}-15=65(3) = 195\\7k=196+15=210\\k = \frac{210}{7}=30[/tex]
Now we can plug K in to find Jon's age:
J = K/3
J = 30/3
J = 10
If Kylie is 5 years older than Ellie and triple Jon's age. If the sum of their ages is 65 then Jon is 12 years old.
Let's assume Jon's age is "J" years.
According to the given information:
1. Kylie is 5 years older than Ellie, so Ellie's age is "J + 5" years.
2. Kylie's age is triple Jon's age, so Kylie's age is "3J" years.
The sum of their ages is 65, so we can set up the equation:
J + (J + 5) + 3J = 65
Now, combine like terms:
5J + 5 = 65
Next, isolate "5J" by subtracting 5 from both sides of the equation:
5J = 65 - 5
5J = 60
Now, divide both sides by 5 to find the value of "J":
J = 60 / 5
J = 12
So, Jon is 12 years old.

Answers
Answer:
its y=x-2
Step-by-step explanation:
If you do -3-2=-5 and if you keep applying that rule you will find that it equals y.
The option that represents the matching representation of the function table is; B: y = x - 2
How to interpret Function Tables?
From the function table given, we see that;
At x = -3, y = -5
At x = -1, y = -3
At x = 0, y = -2
At x = 4, y = 2
At x = 7, y = 5
Looking at the options, the correct one is Option B which is;

Step-by-step explanation:
The semi-perimeter is:
s = (a + b + c) / 2
= (10 + 24 + 26) / 2
= 47
We will find the area of the triangle using the Heron's formula.
A = √[s (s - a) (s - b) (s - c)]
= √[47 (47 - 10) (47- 24) (47 - 26)]

Answer: 41 degrees
Step-by-step explanation:
Given Values : 90 degrees & 49 degrees
Solve : 90 + 49 = 139
Since the sum of all sides of a triangle is supposed to add up to 180 degrees, subtract 180 - 139, and you will end up with 41 degrees.
adding all angles of a triangle gives you 180°. so we know a right angle is 90, and theres another 49. lets add 90 and 49 together, that gives you 139. now last but not least, subtract 180 from 139, and that gives you 41.

60 [tex]ft^{2}[/tex]
Step-by-step explanation:
To find the surface area, you need to find the area of all the shapes that make up the pyramid and add them all together.
The area of the square is simply 36 [tex]ft^{2}[/tex], as it is the length times itself (6x6)
To find the area of a triangle, it is bh/2, where b = base, and h = height. The height is 4 ft, and the base is 6 ft as the length of the square is the same as the base of the triangle. (4x6)/2 = 12.
The area of one of the triangles is 12, and they are all identical and there is 4 of them, so 12 x 4 = 48.
Add that to the area of the square:
48 + 12 = 60
4 triangle faces
1 square
Area of square = length x length in this case 6 x 6 which is 36.
Triangle area = 1/2Bh in this case 1/2 x 6 (4) which is equal to 12.
Now since we have four triangle faces let’s multiply 12 by 4 —> 48.
Add the square to the triangle faces —> 48+36= 84ft^2.

The area of 5 circles and 10 semicircles and 100 quarter circles stones which has the 10 inches radius is 10995.6 in².
What is the area of the circle?The area of the circle is the space occupied by it. It can be given as,
A=πr²
Here, (r) is the radius of the circle.
The radius of one stone is 10 inches. Thus, the area of one circular stone is,
A=πr²
A=π(10)²
A=314.16 in².
There are total 5 circles and 10 semicircles and 100 quarter circles. The area of 5 circle is,
A=5 x 314.16 in²
A=1570.8 in².
The area of circle is twice the area of semicircle and 4 times the area of quarter circle. Thus the area of 10 semicircle and 100 quarter circles is,
A(semicircle)=(10 x 314.16 in² )/2=1570.8 in².
A(quarter circle)= (100x 314.16 in² )/4=7854 in².
The total area is,
A=1570.8 +1570.8 +7854
