Mathematics
1 answer:
user100 [1]4 years ago
3 0

Answer:

9 and 6

Step-by-step explanation:

Write down the system.

The two numbers are x and y.

We are therefore given:

x+y=15

x-y=3

I will solve this for elimination since it is already setup for it.

I will add the columns since both equations are in the same form.

2x+0y=18

2x      =18

Divide both sides by 2:

x        =18/2

Simplify:

x        =9

So if x+y=15 and x=9, then y=6.

The two numbers are 9 and 6.

Test:

9+6=15

9-6=3

A rectangular container that has a length of 30 cm, a width of 20 cm, and a height of 24 cm is filled with water to a depth of 1
BaLLatris [955]

Answer:

5400cm^{3} more water could be added to the container before the container overflows

Step-by-step explanation:

The volume of the rectangular container is got by multiplying its given dimensions: Length X breadth X height

This will be  30 X 20 X 24 = 14400 cm^{3}

To find the volume of water inside the rectangular container, we will use the new height for our computation of volumes, keeping the length and breadth of the cylinder the same.

This will be 30 \times 20 \times 15 =9000 cm^{3}

The volume of water needed to be added until the container overflows will be got by subtracting the volume of water present in the container from the total volume of the container

14400 - 9000 =5400cm^{3}

Note 1 cm^{3}= 1 ml

Today a car is valued at $42000. The value is expected to decrease at a rate of 8% each year. What is the value of the car expec
aleksandr82 [10.1K]
The formula is
A=p (1-r)^t
A future value?
P current value 42000
R rate of decreases 0.08
T time 6 years
A=42,000×(1−0.08)^(6)
A=42000 (0.92)^6
A=25,466.91 round your answer to get 25467

Hope it helps!

What is the value of x if segment BC is 2x+4 and line Ac is 24
miss Akunina [59]

<em>Greetings from Brasil</em>

Let us call the distance AB of Y (in the problem nothing is said about this dimension, so lets call of Y).

From the attached drawing we can conclude that:

AB + BC = AC

where

  AB = Y

  BC = 2X + 4

  AC = 24

then

AB + BC = AC

Y + (2X + 4) = 24

<h2>X = (20 - Y)/2</h2>

<em>In my view this question is incomplete</em>
