Solve the following
system of equations:
5x – 2y = 4
x + 2y = 8
Answer:
x=2
y=3
Explanation
1. Solve x + 2y = 8 for x:
x + 2y = 8
x+2y + − 2y = 8 + −2y(Add -2y to both sides)
x = −2y + 8
2. Substitute −2y + 8 for "x" in 5x − 2y =4
5x − 2y = 4
5 (−2y + 8) − 2y =4
−12y + 40 = 4 (Simplify both sides of the equation)
−12y + 40 + −40 = 4 + −40(Add -40 to both sides)
−12y = −36 (Divide both sides by -12)
y = 3
3. Substitute 3 for "y" in x= −2y + 8
x = −2y + 8
x = (−2) (3) + 8
x = 2 (Simplify both sides of the equation)
Answer:
x = 2 and y = 3

Step-by-step explanation:
Subtract 8 from both sides of the equation.
2x+8=24
2x+8-8=24-8
Simplify
2x=16
Divide both side of the equation by the same term
2x/2 16/2
Simplify
x=8
Subtract the numbers
6x=12-6
6x=6
Divide both side of the equation by the same term

You are throwing a party at an arcade. You recieve 5 tokens for every dollar spent. Create an equation that describes this situation. T is the total number of tokens and D is the number of dollars.
Answer: 5D = T
Step-by-step explanation:
A dollar spent will give 5 tokens.
The amount of dollars spent therefore will increase the number of tokens you by fivefold.
Formula is therefore:
5D = T
Testing it.
Assume you spent 5 dollars, how many tokens would you have:
5D = T
5 * 5 = 25 tokens

Answer:
Point-Slope: y+1=-5/7(x-5)
Slope Intercept: y=-5/7x+ 2 4/7
Standard: -5x+7y=18
Step-by-step explanation:
Slope: -5/7
Point slope is when the equation is in y-y1=m(x-x1) form.
I used the point (5,-1) but it really doesn't matter which one
Substitute it into (x1,y1)
y--1=-5/7(x-5)
y+1=-5/7(x-5) **2 minus signs is equal to 1 plus sign**
Slope-intercept is when the equation is in y=mx+b form.
y=-5/7x+b
To solve for b, plug in one of the points (again, I choose to use (5,-1)
(-1)=-5/7(5)+b
-1=-25/7+b is equal to asking -1=-3 4/7+b
b=2 4/7
Standard form is when it is in Ax+By=C
We'll covert from slope intercept to standard: y=-5/7+ 2 4/7
y=-5/7x+ 2 4/7 is the same as y=(-5/7x+ 18/7)
7y=5x+18 **Multiply both sides by 7, the common denominators**
-5x+7y=18 **Subtract 5x from both sides**

Adrián compró una bicicleta cuyo precio original es de 400.00 pesos pero al pagar en la caja le hicieron 20% de descuento cuánto pagó al niño para la bicicleta
Answer:
320 pesos
Step-by-step explanation:
Un 20% de descuento en formato decimal es 0.20. La totalidad de la bicicleta es representada como 100% o 1 y nosotros queremos saber el precio despues del descuento que seria
100% - 20% = 80% o 0.80
Ahora simplemente multiplicamos este decimal por el valor original de la bicicleta para saber el precio descontado...
400 * 0.80 = 320 pesos
so far two-thirds of the seniors bought prom tickets. if they need minimum of 250 people to attend in order to keep the venue, how many students must be in the senior class to ensure they sold enough tickets
Answer: 375
Step-by-step explanation:

250 x 3=750
750//=375
They need a minimum of 375 students in order to keep the venue,
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, So far two-thirds of the seniors bought prom tickets. if they need a minimum of 250 people to attend in order to keep the venue.
Assuming they need a minimum of x people.
∴ (2/3)x = 250.

Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = [tex]\frac{3-0}{1-0}[/tex] = 3 , then
y = 3x ← is the equation of the graphed line
Write 57 divided 50 as a percentage
Answer:
87.72%
Step-by-step explanation:
What is the fraction (ratio) 50/57 as a percent value?
49/57 = ? ... 51/57 = ?
Detailed calculations below:
Introduction. Fractions
A fraction consists of two numbers and a fraction bar:
50/57
The number above the bar is the numerator: 50
The number below the bar is the denominator: 57
Divide the numerator by the denominator to get fraction's value:
Val = 50 ÷ 57
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Calculate fraction's value.
Divide the numerator by the denominator to get fraction's value:
50/57 =
50 ÷ 57 ≈
0.87719298245614
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.87719298245614 =
0.87719298245614 × 100/100 =
(0.87719298245614 × 100)/100 =
87.719298245614/100 =
87.719298245614% ≈
87.72%;
In other words:
1) Calculate fraction's value.
2) Multiply that number by 100.
3) Add the percent sign % to it.
Answer:
:: written in two ways ::
Not rounded:
50/57 = 87.719298245614%
Rounded to maximum 2 decimals:
50/57 ≈ 87.72%
Signs: % percent, ÷ divide, × multiply, = equal, / fraction bar (division bar), ≈ approximately equal;
