Which system of equations is equivalent to the following system?
2x + 4y = 14
4x + y = 20
A.) 2x + 4y = 14
-16x - 4y = -80
B.) 2x + 4y = 14
-4x + y = -20
C.) 4x + 8y = -28
4x + y = 20
D.) 0-2x - 4y = 14
4x + y = 20
Answer:
A
Step-by-step explanation:
Given :
2x + 4y = 14 ---------- eq 1
4x + y = 20 ---------- eq 2
if you multiply eq 2 by -4 on both sides, you get
-4 (4x + y = 20) = -4 (20)
-16x -4y = -80 --------- eq3
we can see that eq. 1 and eq 2 together forms the system of equations presented in option A, Hence A is equvalent to the orginal system of equations given in the question.
The system of equations which is equivalent to the [tex]2x + 4y = 14[/tex],[tex]4x + y = 20[/tex] is given in option [tex](A)[/tex] i.e. [tex]2x + 4y = 14[/tex] and [tex]-16x - 4y = -80[/tex].
What is system of equations?System of equations comprises of two or more equations and seeks common solutions to the equations.
We have,
[tex]2x + 4y = 14[/tex] [tex]........(i)[/tex]
[tex]4x + y = 20[/tex] [tex]........(ii)[/tex]
Now,
To check that which option suits best for system of equation,
Lets multiply equation [tex](ii)[/tex] by [tex](-4)[/tex],
[tex](-4) (4x + y) = (-4)*(20)[/tex]
[tex]-16x-4y=-80[/tex],
So, this above obtained equation is in option [tex](A)[/tex].
Hence, we can say that the system of equations which is equivalent to the [tex]2x + 4y = 14[/tex] ,[tex]4x + y = 20[/tex] is given in option [tex](A)[/tex] i.e. [tex]2x + 4y = 14[/tex] and [tex]-16x - 4y = -80[/tex].

in a class of 32 students the mean height of the 14 boys is 1.56 meters and the mean height of all 32 students is 1.151 meters. work out the mean height of girls
Answer: Hence, Mean height of the girls is: 1.48
Step-by-step explanation: It is given that:
in a class of 32 students .
the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.
Since there are 14 boys in a class.
So, number of girls is equal to (32-14)=18.
The mean height of 14 boys is 1.56.
Hence the sum of height of 14 boys is= 1.56×14=21.84
Similarly mean height of 32 students is 1.515.
Hence, sum of height of 32 students=1.515×32=48.48.
Let x denote the mean height of 18 girls.
Hence, sum of height of 18 girls is: 18 x.
Now,
18x+21.84=48.48
( since sum of height of girls and boys is equal to the sum of height of all the students)
so, 18x=48.48-21.84
18 x=26.64
Hence, x=1.48
Hence, Mean height of the girls is: 1.48
Which inequality represents the following number line?
+
-10-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
Select one:
a. x < -6
b.X > -6
C.XS-6
d. x > -6
Answer:
b. x > -6
Step-by-step explanation:
> [greater than], and < [less than] inequalities are not filled in because the value is not included, but is only greater or less than.
≥ [greater than or equal to], and ≤ [less than or equal to] inequalities are filled in because the value is included, and it is greater than or less than.
Given that there is an empty circle with an arrow moving in the positive direction from -6, the inequality must be a greater than, and since the value is -6, x > -6.
Solve the system of equations.
7x + 6y = -1
--x + 2y = 3
Answer:
X=-1
Y=1
Solve using Elimination.
Step-by-step explanation:
Multiply the second equation by 7.
The two equations are now:
7x+6y=-1
-7x +14y=21
Combine the two equations
7x and -7x cancel each other out, 14y+6y is 20y, and 21 - 1 is 20.
The equation is now
20y=20, divide 20 on both sides to get Y=1.
Now, substitute 1 as Y in the second equation for -x+2(1)=3
-x+2=3, can be simplified, by subtracting 2 from both sides. Giving us
-x=1.
Divide both sides by -1 for X=-1
Final answers being X=-1, Y=1

The sum of 8 times a number and 7 equals 3.
Answer:
8x + 7 = 3 (x = -0.5)
Step-by-step explanation:
I think this is the equation for what you said
If this is the right equation then x would equal -0.5
(hope this helps)
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
"The sum of 8 times a number (x) and 7 equals 3."
Let, "a number" = x
8x + 7 = 3
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
First, subtract 7 from both sides of the equation:
8x + 7 (-7) = 3 (-7)
8x = 3 - 7
8x = -4
Next, divide 8 from both sides of the equation:
(8x)/8 = (-4)/8
x = -4/8
x = -1/2
-1/2 is your number, or -0.5

Isabelle has $5.45 in her purse. If she has five more nickels than dimes, and twice as many quarters than dimes, how many of each type of coin does she have?
Answer:
Nickel = 13
Dimes = 8
Quarters = 16
Step-by-step explanation:
Let N denote Nickel,
Let D denote dime
Let Q denote quarter
Now, from online conversions;
1 nickel = 5 cents
Also, 1 dime = 10 cents
Also, 1 quarter = 25 cents
Isabelle has $5.45 which is also 545 cents.
Thus, we have;
5N + 10D + 25Q = 545 - - - (eq 1)
We are told that;
she has five more nickels than dimes, and twice as many quarters than dimes.
Thus;
N = D + 5
Also, Q = 2D
Plugging them for N and Q in eq 1 givens;
5(D +5) + 10D + 25(2D) = 545
5D + 25 + 10D + 50D = 545
25 + 65D = 545
65D = 545 - 25
65D = 520
D = 520/65
D = 8
Thus; N = D + 5 = 8 + 5 = 13
Q = 2D = 2 × 8 = 16

Two square rooms have total floor area of 89cm².One room is 3m longer each way than the other,Find the dimension of the two rooms
Answer:
5 m
8 m
Step-by-step explanation:
Area of square = s² ; s = side length
Let the area of each room equal to x and y
x + y = 89cm²
If x = smaller room
y = x + 3 in dimension
Hence,
x² + (x + 3)² = 89
(x +3)(x +3) = x² + 3x + 3x + 9
x² + x² + 3x + 3x + 9 = 89
2x² + 6x + 9 = 89
2x² + 6x - 80 = 0
x² + 3x - 40 = 0
x² + 8x - 5x - 40 = 0
x(x + 8) - 5(x + 8) = 0
x + 8 = 0 ;
x - 5 = 0
x = - 8 or x = 5
Dimension can't be negative :
So, x = 5
Samller square = x = 5
Larger square = x + 3 = 5 + 3 = 8
Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .
Answer:
5.27 lb
Step-by-step explanation:
Given that,
Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :
Let Eric has F floor.
3F = 15.81 ...(1)
We need to find how much flour Eric has.
Dividing both sides by 15.81.
F = 15.81/3
F = 5.27 lb
Hence, Eric has 5.27 lb of flour.
Find the value of x in the isosceles triangle shown below.
please help owo
Answer:
10
Step-by-step explanation:
We will first take a right triangle and we will apply the pythagorean theorem to it. First, the base of the right triangle will be 12/2 which is 6; then, we will just use the theorem.
a^2+b^2 = c^2 (pythagorean theorem)
8^2+6^2 = c^2
100 = c^2
c = 10 because the square root of 100 is 10
