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

find measure of angle 1
Answers
Angles in a triangle add up to 180°
To find the angle next to 36°:
It shows that all together its a 90° angle so you do 90-36= 54°
To find the angle next to 88°:
Angles on a straight line add up to 180° so you do 180-88= 92°
You now have the 2 of the angles in the triangle with angle 1
You now add these 2 angles so 54+92= 146°
and as angles in a triangle add up to 180° you do 180-146= 34°
So angle 1 is 34°

Answers
7y + -4 = 3y + 6
Reorder the terms:
-4 + 7y = 3y + 6
Reorder the terms:
-4 + 7y = 6 + 3y
Solving
-4 + 7y = 6 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
-4 + 7y + -3y = 6 + 3y + -3y
Combine like terms: 7y + -3y = 4y
-4 + 4y = 6 + 3y + -3y
Combine like terms: 3y + -3y = 0
-4 + 4y = 6 + 0
-4 + 4y = 6
Add '4' to each side of the equation.
-4 + 4 + 4y = 6 + 4
Combine like terms: -4 + 4 = 0
0 + 4y = 6 + 4
4y = 6 + 4
Combine like terms: 6 + 4 = 10
4y = 10
Divide each side by '4'.
y = 2.5
Simplifying
y = 2.5

Write 57 divided 50 as a percentage
Answers
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;

Solve the following
system of equations:
5x – 2y = 4
x + 2y = 8
Answers
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

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**

Step-by-step explanation:
I'm going to explain this thoroughly because it seems like you don't have a full understanding of how to do this...practice makes perfect though!
-5+g=-2
The entire point of completing an algebra problem is to find what the variable equals, which means that we need to get the variable by itself. In this case, the variable is g.
The only other thing that is next to g is -5, so we need to add 5 because it is the opposite of subtracting (the sign also always changes when something crosses to the other side of the equation).
-5+g=-2
+5 +5
g=3
This is the solution! I would suggest that you practice these type of small algebra problems if you really don't understand c:

Answers
Answer:
x = 6
Step-by-step explanation:
The Pythagorean Theorem states that a² + b² = c². In this case, c would be the hypothenuse or the longest side, which is 10. 8 can be either a or b.
a² + b² = c²
a² + 8² = 10²
a² + 64 = 100
a² = 36
a = √36
a = 6
So, x = 6.
