Answer:
first equation : 3y + 6×=12
second equation : 4y + 8x = 16
Step-by-step explanation:
first equation
3y + 6× = 12
now take the common ,
3( y + 2x ) = 12
so, y + 2x = 4
second equation
4y + 8x = 16
4 ( y + 2x ) = 16
so, y + 2x = 4

1. Gloria says the two expressions - (12x + 24) - 9x and -6(x + 1) are equivalent. Is she correc Explain how you know.
Answer:
No they aren't equivalent
Step-by-step explanation:
Let's take each expression
the first one is
- (12x+24) - 9x = -12x -24 -9x = -21x -24 = -3 (7x +8)
the second expression
-6 (x+1) = -6x-6
So they aren't equivalent

write down three integers, all less than 25 whose range is 10 and mean is 13
Answer:
Step-by-step explanation:
we have the mean=13
(x+y+z)/3=13
x+y+z=39
range=highest value-lowest value=10
lets say x= highest value
y=lowest value
x-y=10
x=10+y
the numbers are 9,11,19
19-9=10 range
sum is 39
find the are of the ABC triangle
Answer:
The area of the triangle is 48 square centimeters.
Step-by-step explanation:
The area of a triangle is base times height times a half. So the area of the triangle is 12 * 8 / 2 = 6 * 8 = 48 square centimeters.
i need help with number 1
Answer:
Step-by-step explanation:
Given
Points: (0,3) and (-4,-1)
Formula
x = 0 to find the y intercept
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 3
y1 = - 1
x2 = 0
x1 = - 4
m = (3 - -1)/(0 - - 4)
m = 4/4
m = 1
You have y = mx + b so m = 1
the general equation becomes y = x + b
Use point (0,-4)
y = x + b
- 4 = 0 + b
b = - 4
y = x - 4

A student has 6 nickel 14 dimes and 8 quarter.what is the ratios of the total number of coins to the number of nickels ? In simplest form
Given:
A student has 6 nickel 14 dimes and 8 quarter.
To find:
The ratio of the total number of coins to the number of nickels.
Solution:
We have,
Number of nickels = 6
Number of dimes = 14
Number of quarter = 8
Total number of coins = 6+14+8
= 28
Now, the ratio of the total number of coins to the number of nickels is
[tex]Ratio=\dfrac{\text{Total number of coins}}{\text{Number of nickels}}[/tex]
[tex]Ratio=\dfrac{28}{6}[/tex]
[tex]Ratio=\dfrac{14}{3}[/tex]
[tex]Ratio=14:3[/tex]
Therefore, the ratio of the total number of coins to the number of nickels is 14:3.

3² • 9³ = [ ]
solve
Answer:
3⁸ or 6561
Step-by-step explanation:
First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
There are no parentheses, so let's solve the exponents.
3² • 9³
3² = 9
9³ = 729
Your expression is:
9 • 729
Now let's multiply.
= 6561
This number can also be expressed with exponents.
Since 9 = 3², 9³ = 3²⁽³⁾
Now your expression is:
3² • 3²⁽³⁾
First, solve the exponents by multiplying.
3² • 3⁶
When you multiply two expressions with exponents that have the same base (3), you add the exponents.
3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸
3⁸ also equals 6561.
Your answer is 3⁸ or 6561.
Hope this helps!
(x-h)^2+(y-k)^2=r^2
Derive standard form of an equation of a circle with center C(5,2) and radius r=4, using the Pythagorean theorem.
Answer:
(x-2)^2 + (y - 5)^2 = 16
Step-by-step explanation:
Given the standard form of an equation of a circle
(x-h)^2+(y-k)^2=r^2
If (h, k) = (5,2) and r = 4
Substitute
(x-2)^2 + (y - 5)^2 = 4^2
(x-2)^2 + (y - 5)^2 = 16
Hence the required equation is (x-2)^2 + (y - 5)^2 = 16
Angel has xx dimes and yy nickels. He has at most 13 coins worth no less than $0.95 combined. Solve this system of inequalities graphically and determine one possible solution.
Answer:
a possible solution is (10,1)
Step-by-step explanation:
Here, we want to solve the given inequality and determine one possible solution
From the question, we have it that;
x + y ≤ 13
Mathematically, we have it that 1 dime is worth $0.1
A nickel is worth $0.05
0.1x + 0.05y ≥ 0.95
please check the attachment for the graph of both equations
The point of intersection represents the solution.
we have a point here as (10,1)
