Construye una recta numerica en tu cuaderno y representa en ella los numeros -2;0,5 y 4 describe el prosedimiento

Answer:

A

Step-by-step explanation:

If it loses 15% of its value every year, then each subsequent year will be worth 85% of the previous year. If we think of this as a geometric series, then the worth would be 8000(.85^t) where t is years after the first year. If you plug in 12, then it's 1137.93.

Answer:

1137.93 is the answer

Step-by-step explanation:

Answer:

The distance is 13 units

Step-by-step explanation:

13 - 1 = 12

6 - 1 = 5

12² + 5² = c²

144 + 25 = c²

√169 = c

c = 13

(I could have used the distance formula, but the pythagorean theorem is shorter for this problem)

Answer:

square is the answer...

Answer:

c

Step-by-step explanation:

m<4 and m<3 is a straight angle. straight angles are equal to 180 degrees. the friend found m<3=40 and m<4 is equal to 140 degrees (im not good at explaining, sorry)

have a great day :D

Answer:

eric = 15

chris 7

Step-by-step explanation:

Let the questions Chris answered correctly be represented by c

Let the questions Eric answered correctly be represented by e

They both got 22 questions right. This can be represented by this equation :

c + e = 22 --- eqn 1

Chris scored 8 less than Eric. This can be represented by this equation :

c = e - 8 --- eqn 2

Substitute for c in eqn 1  

e - 8 + e = 22 .

collect like terms

2e = 30

solve for e

e = 15

Substitute for e in eqn 2

c = 15 - 8 = 7

y=-1x/4

this is the best way to represent this,

Answer:

Step-by-step explanation:

M = ¾J

If you look at the numbers M is always 3/4 of J so the equation is M = ¾J

my phone is gonna die u can use photomath it will give u the answer hope it helped:)))))))

Answer:

you can get 18 and add it to something

Answer:

17 miles away

Step-by-step explanation:

if you draw, you get a right angle triangle.

use pythagorean theorem

c² = a²+b²

c² = 15² + 8²

c² = 225 + 64

c= sqrt(289)

c = 17

12. Let's factor x2−9x+8

x2−9x+8

The middle number is -9 and the last number is 8.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -9

Multiply together to get 8

Can you think of the two numbers?

Try -1 and -8:

-1+-8 = -9

-1*-8 = 8

Fill in the blanks in

(x+_)(x+_)

with -1 and -8 to get...

(x-1)(x-8)

15. Let's solve your equation step-by-step.

(x−2)(x−3)=2

Step 1: Simplify both sides of the equation.

x2−5x+6=2

Step 2: Subtract 2 from both sides.

x2−5x+6−2=2−2

x2−5x+4=0

Step 3: Factor left side of equation.

(x−1)(x−4)=0

Step 4: Set factors equal to 0.

x−1=0 or x−4=0

x=1 or x=4

Sorry I wasn't able to do 13 and 14 but hope this helps! :)

Answer:

276 individuals at the party.

Step-by-step explanation:

If 6 of your friends are couples then we would count them as 1 each and it would be 3 friends. Therefore we subtract 3 from your 58 friends.

58 - 3 = 55 friends

Each of them brings 5 friends so we multiply your number of friends by 5.

55 * 5 = 275 friends

Finally, we add you because you are included

275 + 1 = 276

There will be a total of 276 individuals at the party.

Answer:

x + y = 1042

1.50x + 0.75y = 1140

Step-by-step explanation:

If there was a total of 1,042 fares paid then x + y would be equal to that because x is the number of regular fares paid and y is the number of reduced fares paid.

If there was a total of $1,140 made from the fares then we can use 1.50x + 0.75y. We put the 1.5 in front of the x because each fare paid costs $1.50, same with Y each reduced fare paid is $0.75. So both of those need to be added up to get $1,140.

Answer:

5x + 6

Step-by-step explanation:

4 + 2 is 6 and there is no other number with x so you leave the 5x alone
