Alejandro recibio su tiket de compra por 2 cajas de pastillas de $320 cada uno y un costo de aplicación y revisión. Su pago final fue de $470 ¿Cuánto pagó por su pago por la aplicación y revisión? Plantea la ecuación.
Answer:
$150
Step-by-step explanation:
Costo de 2 cajas de pastillas = $ 320
Costo de la solicitud y tarifa de revisión = x
La ecuación se da como:
320 + x = 470
x = 470 - 320
x = 150
El costo de la solicitud y la tarifa de revisión = $ 150
Find the value of x. 120
Answer:
x = 25
Step-by-step explanation:
2x + 70 = 120 {Subtract 70 from both sides}
2x = 120 -70
2x = 50 {divide both sides by 2}
x = 50/2
x = 25

Find the value of x.
Answer:
x= 128*
Step-by-step explanation:
180*-52*=128*
Answer:
x = 128
Step-by-step explanation:
well we know that for a polygon, the interior angles always add up to 360.
One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128

Write an expression equivalent to m + m + m + m that is a sum of two terms.
Answer:
5m
Step-by-step explanation:
add them and add 1
An expression equivalent to m + m + m + m as a sum of two terms is 4m.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is:
m + m + m + m
Equivalent expressions are expressions that work the same even though they look different.
We can combine like terms to simplify the expression:
m + m = 2m
Now plug in the expression of m+m in the given expression.
So the expression becomes:
m + m + m + m = 2m + 2m
Now we have expressed the given expression as a sum of two terms, which are both 2m:
2m + 2m = 4m
Therefore, an expression equivalent to m + m + m + m as a sum of two terms is 4m.

Answer:
y=9x
Step-by-step explanation:
First let's find the slope of this.
To find the slop we can take two points.
(1,9) & (3,27)
27-9/ 3-1 (slope equation) = 18/2=9
The slope of the equation is 9.
Now let's use point-slope form to find the equation.
(1,9)
y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)
y-9=9(x-1) (substitute m for the slope)
y=9x-9+9
y=9x
If each quadrilateral below is a trapezoid, find the missing measures.
#1
Answer:
C = 101
E = 46
Step-by-step explanation:
79 + 134 = 213
180 - 79 = 101 (C+F has to equal 180)
79 + 134 + 101 = 314
360 - 314 = 49 (trapezoids have a total degree of 360)
The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.
It is given in the picture that measures the angles of a trapezoid.
It is required to find the other angles.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.
We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°
We know in trapezoid:
∠C+∠F = 180° and
∠D+∠E = 180°
For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°
For ∠E = 180° - ∠E ⇒ 180° - 134° ⇒46°
We have another trapezoid JKLM in which ∠K = 83°
We know in isosceles trpezoid:
∠K = ∠J = 83° and
∠L = ∠M
∠L = 180° - ∠K ⇒ 180° - 83° ⇒ 97° ⇒ ∠M
Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

Math help please answer question a and b ( show work please)
Answer:
a) 24 degrees
b) 50 degrees
Step-by-step explanation:
part a : use sine-1
sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]
sine-1 = [tex]\frac{17}{42}[/tex]
sine-1 = 0.405
missing angle = 23.89
round to the nearest degree = 23.89 = 24
part b : use cosine-1
cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]
cos-1 = [tex]\frac{16}{25}[/tex]
cos-1 = 0.64
missing angle = 50.208
round to the nearest degree = 50.208 = 50

The radius of a cylindrical gift box is (3x+1) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder? Write your answer as a polynomial in standard form.
Answer:
56πx² + 36πx + 6π square inches
Step-by-step explanation:
The radius of a cylindrical gift box is (3x+1) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder? Write your answer as a polynomial in standard form.
The surface area of a cylinder is given as:
2πr(r + h)
The radius of a cylindrical gift box is (3x+1) inches.
The height of the gift box is twice the radius = 2(3x + 1) inches
= 6x + 2 inches
The surface area of the cylinder is:
= 2 × π × 3x + 1( 3x + 1 + 6x + 2) square inches
= 2 × π × 3x + 1(9x + 3) square inches
= 2π × 3x + 1(9x + 3) square inches
= 6πx + 2π( 9x + 3) square inches
= 6πx (9x + 3) + 2π( 9x + 3) square inches
= 56πx² + 18πx + 18πx + 6π square inches
= 56πx² + 36πx + 6π square inches
The surface area of the cylinder is 56πx² + 36πx + 6π square inches
