Answer:

x+y=0 and 3x-2y=10

Step-by-step explanation

Let the numbers be x and y.

The sum of the two numbers is 0

\implies \: x + y =0

Letting the smaller number be y and the

larger number be x:

twice the smaller number

\implies \: 2y

Also, 3 times the larger number

\implies \: 3x

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

\implies \: 3x - 2y = 10

Therefore the equations are

x + y =0

and

3x  - 2y =10

Caleb and Mike both score the same amount of points in a game. Caleb has fifteen less than the total number of points. Mike has
elena-s [515]
Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.

Geraldo recently saw a newspaper ad for a new version of his laptop. the projected price is $400.00, and the laptop will be out
Tanya [424]

The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.

Given that:-

Price of the laptop after 1 year = $ 400.

Inflation rate = 2.5 %

We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.

Let the price he had to pay be x.

Hence, we can write,

x + (x*(2.5)*1)/100 = 400

x(1 + 1/40) = 400

x(41/40) = 400

x = 400*40/41 = $ 16000/41 = $ 390.24.
