Para reformar su cocina, Berta compró la semana pasada 2 cajas de baldosas de plaquetas para el suelo y 4 cajas de baldosas para la pared por 200 €.
2x + 4y = 200 ...... Ecuación 1
Hoy
Hoy compré 2 cajas más de plaquetas y otras 2 de tejas por 130 €.
2x + 2y = 130 ..... Ecuación 2
Resolvemos usando el método de Eliminación
2x + 4y = 200 ...... Ecuación 1
2x + 2y = 130 ..... Ecuación 2
Restar la ecuación 2 de 1
2 años = 70
y = 70/2
y = 35 €
Resolviendo para x
2x + 4y = 200 ...... Ecuación 1.
2x + 4 × 35 = 200
2x + 140 = 200
2x = 200 - 140
2x = 60
x = 60/2
x = 30 €
el costo de
Caja de plaquetas = x = 30 €

Answer:
they want u to replace the letters with the numbers and then solve the equation. so instead of having c/a+2b they want you to write 6/3+2(-4)
then they want u to solve it. 6/3=2 and 2(-4)=-8 finally add 2 and -8 to get the answer -6. (you probably need to write it step by step not just say what the answer is)

Answer:
[tex] m\angle BDC = 95\degree [/tex]
Step-by-step explanation:
[tex] In\: \triangle ACD\: \&\:\triangle BDC[/tex]
[tex] m\angle A = m\angle B[/tex] (given)
[tex]\because m\angle A = 50\degree [/tex]
[tex]\therefore m\angle B = 50\degree [/tex]
[tex] m\angle ADC = m\angle BCD[/tex] (given)
[tex]\because m\angle ADC = 35\degree [/tex]
[tex]\therefore m\angle BCD= 35\degree [/tex]
[tex] In\: \triangle BDC[/tex]
[tex] m\angle BDC = 180\degree - (m\angle B+m\angle BCD) [/tex]
(By angle sum postulate of a triangle)
[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]
[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]
[tex] m\angle BDC = 180\degree - 85\degree [/tex]
[tex] m\angle BDC = 95\degree [/tex]

The goal of the students was to raise $600. They sold 6% rolls of paper. By what amount did
the students miss their goal of raising 5600? Show or explain all of your work
Answers
Answer:
So The Answer would be 600=1.05x and 600=1.06x for part A and B
Step-by-step explanation:
For Part B If there goal is to raise 600$ then 5% of 600$ = 30$ per roll of wrapping paper;
Part A: 600= 1.05x
The expression 1.05 represents the 5% increase for X wrapping paper sold to the equivalent of 600$
For end of the Question Im unsure what they mean they "missed there goal of raising 5600?.. 5600$ or 560.0$?"

Answer:
y = 2x+1
Step-by-step explanation:
From the question,
Using the equation of a straight line
y = mx+c................. Equation 1
Where m = slope of the line, c = intercept on the y axis.
From the graph, The two point co-ordinate shown os
Point 1 = (-2,0)
Point 2 =(6,4)
s = (y₂-y₁)/(x₂-x₁).............. Equation 2
Where y₂ = 6, y₁ = -2, x₂ = 4, x₁ = 0
Substitute into equation 2
s = (6-(-2))/(4-0)
s = (6+2)/4
s = 8/4
s = 2.
Also from the graph,
c = 1
Substitute these values into equation 1
y = 2x+1
Hence the equation of the line is y = 2x+1

NEED ASAP Which line is parallel to the line y=4x-2?
Answers
Answer:
y = 4x + 1
Step-by-step explanation:
Given the equation y = 4x - 2, we need to find the equation parallel to this line. Note that for two equations to be parallel to each other, the must have the same slope
Standard form of an equation is y = mx + b
Compare;
mx = 4x
m = 4
Since the slope of the given equation is 4, the required equation must also have a slope of 4
Since we are not given an option, we can assume any equation with a slope of 4
y = 4x + 1 will be parallel to the given equation since they both have the same slope
Note that the equation can be different so far they have the slope of 4
