Si tengo $ 86 pesos y compro 3 libros de 1 ! " cada uno y seis objetos de a $ # " cada uno, ¿cuánto me queda? R = 77 $ " � %!& "
Answer:
Originalmente tenés $86 pesos.
Compras 3 libros de " 1 ! " cada uno.
(voy a suponer que 1 ! es un valor)
Entonces tenés que pagar 3 veces el valor 1 !
Esto significa que ahora tendrás:
$86 pesos - 3*(1 !)
Y ahora compras 6 objetos de $# cada uno.
Entonces tenés que pagar 6 veces $#.
Esto significa que tenemos que restar 6*$# a lo que te quedaba, entonces ahora vas a tener:
$86 - 3*(1 !) - 6*($#)
Este será tu resto después de la compra.
Wich equation represents the relationship between x and p?
Solve the simultaneous equations
3x−2y=27
3x−y=24
x=? y=?
I can do this easily with positives but somehow I just don't understand a bit in negatives, can anyone help?
None of my answers are working.
Answer:
3x-2y=24 _____ (1)
2x-3y=18 _____ (2)
multiply (1) by 2
6x - 4y = 48
multiply (2) by 3
6x-9y=54

The x and y value from the given system of equations are 7 and -3 respectively.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
The given simultaneous equations are 3x-2y=27 ------(I) and 3x-y=24 ------(II) .
Subtract equation (I) from (II), we get
3x-y-(3x-2y)=24-27
⇒ y=-3
Substitute y=-3 in equation (I), we get
3x-2(-3)=27
⇒ 3x=21
⇒ x=7
Therefore, the x and y value from the given system of equations are 7 and -3 respectively.

The sum of the heights of two brothers is 10 feet, 4 inches. The difference between their heights is 10 inches. How tall is the shorter brother? (12 inches = 1 foot; Remember to convert into inches first and then into feet at the end.) Let the height of the taller brother = x and the height of the shorter brother = y.
4.75 ft
4.5 ft
4 ft
4.58 ft
Answer:
4.5 ft
Step-by-step explanation:
Let us assume the height of the taller brother be x
And, the height of the shorter brother be y
Now according to the question
x + y = 10.33
x - y = 0.833
Now solve these two equations
2x = 11.666
x = 5.833
y = 10.33 - 5.83
= 4.5 ft

if I is parallel to m, find the value of X and Y
Answer:
x = 21
y = 15
Step-by-step explanation:
Exterior angles on the same side of the transversal are supplementary
So, 3x - 16 + 6x + 7 = 180
9x -9 = 180
9x = 189
x = 21
11y - 32 = 6x + 7 since the angles are vertical angles
11y - 32 = 6(21) + 7
11y - 32 = 126 + 7 = 133
11y = 165
y = 15
Draw a diagram of x + 3 and 2x for each situation:
x = 1
x = 2
x = 3
x = 4
The diagram of x + 3 and 2x are as drawn in the image attached
How to draw a diagram of x + 3 and 2x?Given the situations: x = 1, x = 2, x = 3 and x = 4
For x + 3
x = 1, x+3 = 4
x = 2, x+3 = 5
x = 3, x+3 = 6
x = 4, x+3 = 7
For 2x
x = 1, 2x = 2
x = 2, 2x = 4
x = 3, 2x = 6
x = 4, 2x = 8
You will use the values of x and y = x+3, and the values of x and y = 2x to draw the diagram of the lines as shown in the attached image

Cynthia besch wants to buy a rug for a room that is 18ft wide and 35ft long she wants to leave a uniform strip of floor around rug she can afford to buy 528 ft of carpeting what dimensions should rug have
Answer:
rug long = 34 ft
rug wide = 17 ft
Step-by-step explanation:
given data
wide = 18 ft
long = 35 ft
area of carpet = 528 ft
solution
we get here area of floor that is
and we consider length of carpet = 35 - 2x
and width = 18 - 2x
(35 - 2x) × (18 - 2x) = 528 ...................1
solve it we get
x = 25.5 and x = 1
we choose 1 ft. as the width of the strip
so rug long = 35 - 1 = 34 ft
and rug wide = 18 - 1 = 17 ft

HELP QUICK!! solve by substitution and show work please
Answer:
(-1,-3)
Step-by-step explanation:
Substitute y=x-2 into y=4x+1
x-2=4x+1
substract -1 on both sides.
x-3=4x
subtract x on both sides
-3=3x
divide by 3 on both sides
x=-1
Substitute -1 into equation
y=x-2
y=(-1)-2
y=-3
So it would be (-1,-3)
