Answer:
20 m
Step-by-step explanation:
ancho = x
largo = x + 60
área = largo × ancho
1600 = (x + 60)x
x² + 60x - 1600 = 0
(x + 80)(x - 20) = 0
x + 80 = 0 o x - 20 = 0
x = -80 o x = 20
Answer: 20 metros

How many total points does Irma have now?
Irma has a total point of -8 now.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given that, Irma is just learning to play the Happy Fairies video game.
In the game, based on the taking care of fairies, players gain and lose points.
Initial point Irma had = -5 points
Fairy fell over in the wind and she got -3 points.
Final point = -5 + -3
= -5 - 3
= -8
Hence the total points now is -8.

How many ways are there to arrange 1,2,3,4,5 in a line, such that n is not in the nth position?
For Example: 2,1,3,4,5 is not valid because 3 is the 3rd in the line but 2,1,4,5,3 is valid because none of the numbers are in their original position.
Answer:
256 ways
Step-by-step explanation:
Okay so n cannot be in the nth place, but there are 5 places available.
So thinking about it technically you can have 4 of each number in a different spot not their own, and 4x4x4x4 = 256
However, if that doesn't work, you could try 4! which is 4x3x2x1 = 24
Hope that helps :)
What are the slope and y-intercept of the line? Question 2 options:
Slope = 6, y-Intercept = 170
Slope = -170, y-Intercept = 1020
Slope = 1020, y-Intercept = -170
Slope = 170, y-Intercept = 6
Answer: SLOPE=-170, Y-INTERCEPT = 1020
Step-by-step explanation:
Calculate the slope: Take any two points and find the changes in x and y:
I'll use (4, 340) and (6, 0):
Change in y (the rise) is (0 - 340) = -340.
The change in x is (6-4) = 2
The slope is the rise (y) over the run (x): -340/2 or -170.
The y-intercept is the value of y when x=0. The f=-data provided has a value for y at x=0: (0,1020). So the interecpt is 1020.

What is the name of the property illustrated below?
3(x+4)=(x+4)+3
a :associative property of addition
b :commutative property of addition
c: associative property of multiplication
d: commutative property of multiplication
Step-by-step explanation:
I think you made a mistake with the equation.
because that property, that you presented, did not exist.
but
3(x+4) = (x+4)3 exists
and it is the commutative property of multiplication (a×b = b×a).
Did you mention that multiplication is a shortcut for repeated addition?
Step-by-step explanation:
yes, in a similar way as division is a shortcut for repeated subtraction.
you do know, that you normally have to add the points win in a game, right ?
so, your score grows by 200 points each time you score.
that means
200
200
200
...
200
what do you think you do to get the total ? you add all the points.
you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.
but you did not have 200 hits, you only got 12 hits.
so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).
and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.
that is how multiplication works and helps with additions.

Answer:
(-1, 7)
Step-by-step explanation:
Step 1 - Make the two equations equal the same:
3x + y = 4
2x + y = 5
Add 1 to the first equation:
3x + y + 1 = 5
2x + y = 5
3x + y + 1 = 2x + y
Step 2 - Subtract 2x from both sides to isolate y:
3x + y + 1 = 2x + y
3x - 2x + y + 1 = 2x - 2x + y
x + y + 1 = y
Step 3 - Subtract y from both sides:
x + y + 1 = y
x + y - y + 1 = y - y
x + 1 = 0
x = -1
Step 4 - Plug known variable back into the first equation:
3x + y = 4
3(-1) + y = 4
-3 + y = 4
Step 5 - Add 3 to both sides to isolate the y:
-3 + y = 4
-3 + 3 + y = 4 + 3
y = 7
Meaning the two coordinates are:
x = -1
y = 7
Or:
(-1, 7)

The temperature of a substance in an experiment changes by -7.5°F from 8 a.m. to 2 p.m. At 5 p.m., the temperature is 43.5°F. It is 1/3 of what the temperature was at 2 p.m. What was the temperature at 8 a.m. of the substance?
Answer:
ok
Step-by-step explanation:
Answer:
138* F
Step-by-step explanation:
If 43.5 is 1/3 of what it was at 2 p.m. then we need to multiply the equation by three where we get 130.5. Since it changed by -7.5 we have to add 7.5 to get our final answer of 138 degrees at 8 P.M.
