Answer:
a) x=3
b) z=10
c) P= 2
d) X=7
e) U=1
Step-by-step explanation:
Resolver una ecuación consiste en hallar los valores de la variable que hacen cierta la igualdad.
a) 2x= 6
El coeficiente es el número junto a la variable. En este caso, el coeficiente es 2. Para eliminar este número en la expresión 2x, debido a que la variable x esta multiplicada por 2, deberás dividir ambos lados de la ecuación entre 2, debido a que la operación opuesta de la multiplicación es la división.
(2x)÷2=6÷2
x= 3
Comprobar la solución de una ecuación se hace al remplazar la variable en una ecuación con el valor de la solución. La solución debería satisfacer la ecuación cuando se ingresa en esta.
En este caso:
2*3= 6
6=6
b) 10 + z= 20
En este caso se debe sumar o restar la constante que se encuentra acompañando a la variable en ambos lados de la ecuación de manera de aislar el término de la variable. En este caso:
10 - 10 + z= 20 -10
z= 10
Comprobación:
10 + z=20
10 + 10=20
20=20
c) P + 9= 11
P +9 - 9= 11 -9
P=2
Comprobación:
2 + 9= 11
11=11
d) 3X + 8 = 29
En este caso, se suma o resta la constante en ambos lados de la ecuación y luego se elimina el coeficiente de la variable mediante la división o multiplicación. Esto es:
3X + 8 - 8= 29 - 8
3X= 21
3X ÷3= 21÷3
X=7
Comprobación:
3*7 + 8=29
21+8=29
29=29
e) 2U + 8= 10
2U + 8 - 8= 10 -8
2U= 2
2U ÷2= 2÷2
U=1
Comprobación:
2*1 + 8= 10
2 + 8= 10
10=10

The value of the perpendicular x will be 7.64 units.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
Then the tangent of an angle is the ratio of the perpendicular and the base of the right-angle triangle.
tan θ = P / B
Then we have
tan 27° = x / 15
x = 7.64 units

The probability of a chance event is 0.5, it is __________ to happen when compared to a chance event with a probability of 1.
Answer: less likely
Step-by-step explanation:
Given
The probability of an event is 0.5
The value of probability always lies between 0 and 1. 0 represents that event will not while 1 represents the certainty of the event.
When 0.5 is compared with 1, it is less likely to happen i.e. chances of this event to occur are less compared to the a event with probability of 1.

Please help I can’t figure this question out
Answer:
7/50 is the correct answer
Step-by-step explanation:
First you would need to convert this to an improper fraction which it would be 0+14/100.
Then you would add 0 and 14/100 to get the same answer 14/100
After this you would factor out the 14 and 100
Finally you should get
2(7)/ 2(50)
Now you should be able to cancel out the 2 and be left with 7/50.
Hope this helps!!!

find the area 5.3in, 8in,4in,8in no links please!
Answer:
45.4 in is the answer :)
Step-by-step explanation:
you have to split up the shape. I decided to do it into three different parts one long at the bottom with side lengths of 8 and 4. a smaller rectangle at the top left with measurements of 5.3 and 4, (8-4=4) and the triangle which is 4 by 2.7 (8-5.3). You then find the area of each individual shape, for the rectangles you just multiply getting 32 and 21.2 for the smaller one and then find the triangle by using the formula 1/2b*h which gets you 5.4 then you add the three areas together getting 45.4 hope this helps!
Answer: 45.4 is the answer
You cucullate the base x height and then subtract the 4 in. and 5.3 in.
The perimeter of a photograph is 34 inches. It is 10 inches long. How wide is it?
inches
Answer:
the width of the photo is W = 14" / 2, or 7"
Step-by-step explanation:
Recall that P = 2W + 2L. Here L = 10" and P = 34".
Thus, 2(10") + 2W = 34", or
2W = 14"
Then the width of the photo is W = 14" / 2, or 7"

The numbers 1 to 8 are placed in a hat. What is the probability that you will pick an odd number, and without replacing the number in the hat, select the number 2?
Answer:
1 /7
Step-by-step explanation:
Sample space =. (1, 2, 3, 4, 5, 6, 7, 8)
Odd numbers = (1, 3, 5, 7)
Probability of picking an odd number = number of odd numbers / sample space
P(odd number) = 4 / 8 = 1/2
Without replacement :
P(picking a 2) :
Sample space = 8 - 1 = 2
Hence,
P(picking a 2) = 2 / 7
P(picking an odd number and the a 2) =
1/2 * 2/7 = 2 /14 = 1/7

Answer:
A. y = -2x + 2 B. y = x - 1
Step-by-step explanation:
A.
We have two given points, which are (0, 2) and (1, 0). Because one of the given points has the x-coordinate 0, it means it is the y-intercept. The y-intercept is 2, which means that 2 is the B of our equation. Now, I will use the skeleton method to find the slope.
((2) - (0))/((0) - (1)) = -2
Now we know that -2 is the slope, so we can form the equation.
y = -2x + 2
B.
The line shown in exercise B is actually a 1x equation since it is seen that it goes through every whole number without forming decimals. So our m is 1. The y-intercept, which can be seen by looking at the y-coordinate at x = 0, is -1. So -1 is our B.
The equation is as follows.
y = x - 1
