Solve the following system by substitution. 7x + 2y = 16 –21x – 6y = 24 What is the solution ?
Answer:
no solution
Step-by-step explanation:
x=(16-2y)/7
-21*(16-2y)/7-6y=24
-3(16-2y)-6y
-48+6y-6y=24
-48=24
you can't solve for the variables
There is no solution for given system of equations.
System of equations :The given equations are,
[tex]7x+2y=16\\\\x=\frac{16-2y}{7}[/tex]
Another equation is, [tex]-21x-6y=24[/tex]
Substitute value of x in above equation.
[tex]-21(\frac{16-2y}{7} )-6y=24\\\\-48+6y-6y=24\\\\-48\neq 24[/tex]
Thus, there is no solution for given system of equations.

GIVING BRAINLIEST!!! PRETTY SIMPLE QUESTION!!!
Mei subscribed to a magazine at a rate of $24 for 12 issues. When she placed her order, Mei used a coupon that added 3 free bonus issues to her subscription. How did the coupon impact the cost per issue of Mei’s subscription?
O The coupon lowered the cost per issue by $0.40.
O The coupon lowered the cost per issue by $1.38.
O The coupon raised the cost per issue by $0.13.
O The coupon raised the cost per issue by $0.67.
Answer:
A
Step-by-step explanation:
Originally, Mei pays $24 for 12 issues.
Therefore, the cost per issue is:
[tex]c=\frac{\$24}{12\text{ issue}}=\$2\text{ per issue}[/tex]
With the coupon, Mei pays the same amount of $24 but for 15 issues.
So, the cost per issue now is:
[tex]c=\frac{\$24}{15\text{ issues}}=\$1.60\text{ per issue}[/tex]
Therefore, the coupon lowered the price of the issue by $0.40.
Our answer is A.
Answer: The coupon lowered the cost per issue by $0.40.
Original price of issue: $2
24 ÷ 12 = 2
Mei added 3 more issues, but she still pays $24.
The answer is A.
Hope this helps you!

Figure 3
62°
144 what is the angle measure in degrees for thr missing variable x in figure
The value of the angle x is equal to 98°.
Given that the figure attached below.
To find the angle x, follows sum steps as:
Draw one parallel line between the given parallel lines with intersect the point x.
By linear sum,
Angle 1 on below parallel line is 180° - 144° = 36°.
Angle 2 is equal to angle 1, that is, angle 2 is equal to 36°.
Angle 3 on centre parallel line is equal to 62°.
So, the angle x is calculated as:
x = Angel 2 + Angle 3
x = 36° + 62°
x = 98°
Hence, the required angle is equal to 98°.

Find the measure of x in each figure. (Look at photo)
Answer:
x = 20
Step-by-step explanation:
these angles are supplementary, which means they add up to 180°
using this, you can make the following equation:
6x + 60 = 180
subtract 60 from both sides of the equation
6x + 60 - 60 = 180 - 60
6x = 120
divide both sides of the equation by 6
6x/6 = 120/6
x = 20

Answer:
a) root77
b) 2 root77 / ~17.55 cm^2
Step-by-step explanation:
a) by using Pythagorean Theroem,
a^2 + b^2 = c^2
2^2 + b^2 = 9^2
4 + b^2 = 81
81 - 4 = b^2
77 = b^2
root77 = b
b) 1/2bh is the quation for area thus,
area = 1/2 ( 4 ) ( root77)
area = 2 root77
or area = ~17.55 cm^2
h = [tex]\sqrt{77}[/tex]
A =[tex]2\sqrt{77}[/tex]
Step-by-step explanation:Rules for solving this problem:
Isosceles triangle rules
∠C = ∠ABC = BABecause of isosceles being made up of two right triangles; using the pythagorean theorem we can deduce that
(1/2 x AC)² = BC² - h² (1/2 x AC)² = BA² - h²Area of a triangle
A = 1/2 (Base x Height) = 1/2 * bhStep 1 - Find the height
[tex]h =\sqrt{9^2 - ((1/2)AC)^2} = \sqrt{9^2 - ((1/2)~4)^2} = \sqrt{9^2 - 2^2} = \sqrt{81-4} = \sqrt {77}[/tex]
Step 2 - Find the area

Step-by-step explanation:
What is the solution to this equation?
2x + 3 = x − 4
Answer:
x = −7
Step-by-step explanation:
2x + 3 = x − 4
Subtract 3 from both sides of the equation
2x = x −7
Subtract x from both sides of the equation
x = −7
Answer:
X=7
Step-by-step explanation:
Step 1
Having all the
x
terms on one side of =
Subtract
2 x
from both sides
2 x − 2 x + 3 = 3 x − 2 x − 4
0 + 3 = x − 4
Swap round
x − 4 = 3
Step 2
Have just
x
on the left of =
Add
4
to both sides
x − 4 + 4 = 3 + 4
x = 7
identify the zeros of f(x) = (x + 9)(x − 4)(6x + 1).
Answer:
x = - 9, x = - [tex]\frac{1}{6}[/tex], x = 4
Step-by-step explanation:
To obtain the zeros, equate f(x) to zero, that is
(x + 9)(x - 4)(6x + 1) = 0
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 4 = 0 ⇒ x = 4
6x + 1 = 0 ⇒ 6x = - 1 ⇒ x = - [tex]\frac{1}{6}[/tex]

what are a couple ways to simplify 3(x-5)-4=17
Simplifying
3(x + -5) + -4 = 17
Reorder the terms:
3(-5 + x) + -4 = 17
(-5 * 3 + x * 3) + -4 = 17
(-15 + 3x) + -4 = 17
Reorder the terms:
-15 + -4 + 3x = 17
Combine like terms: -15 + -4 = -19
-19 + 3x = 17
Solving
-19 + 3x = 17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '19' to each side of the equation.
-19 + 19 + 3x = 17 + 19
Combine like terms: -19 + 19 = 0
0 + 3x = 17 + 19
3x = 17 + 19
Combine like terms: 17 + 19 = 36
3x = 36
Divide each side by '3'.
x = 12
Simplifying
x = 12

8x=32
x=32/8
x=4
Answer:
x = 4
Step-by-step explanation:
First you look at the two values of the equation, so the difference between the difference of the two variables is 32, ( 37 - 5 ) then we know that ( 12x - 4x ) 8x . So we know that 8x equals to 32, so ( 32/8 ) equals to x = 4.
