Mathematics
1 answer:
Fantom [35]3 years ago
6 0

Answer:

Step-by-step explanation:

-5+8x-9=3(x+3)

8x-14=3x+9

8x-3x-14=9

5x-14=9

5x=9+14

5x=23

x=23/5

----------------------

-216-3x=-12+6x

-216-3x-6x=-12

-216-9x=-12

9x=-216-(-12)

9x=-216+12

9x=-204

x=-204/9

x=-68/3

------------------

6-213-2x=-413-x

-207-2x=-413-x

-207-2x-(-x)=-413

-207-2x+x=-413

-207-x=-413

x=-207-(-413)

x=-207+413

x=206

------------------------

-(4x+9)=2x-3(2x+3)

-4x-9=2x-6x-9

-4x-9=-4x-9

Infinitely many solutions.

The least common multiple of two whole numbers is 60. The ratio of the greater number to the lesser number is 6:5. WhAt are the
maks197457 [2]

Answer:

The two numbers are 12 , 10

Step-by-step explanation:

Given as :

The least common multiple of two numbers = LCM = 60

The ratio of the greater number to lesser number = 6 : 5

let the greater number = 6 x

And The smaller number = 5 x

∵ The LCM of numbers = 60

So, 6 × 5 × x = 60

Or,  30 × x = 60

∴  x = \frac{60}{30}

I.e x = 2

So The greater number = 6 x = 6 × 2 = 12

And  The smaller number = 5 x = 5 × 2 = 10

Hence The two numbers are 12 , 10 Answer

During the first few years of a tree's life, its growth rate is linear. For example, an oak tree grows at a rate of 1.5 feet per
Pavlova-9 [17]

Answer:

Mostafa's maple tree grows at a slower yearly rate than an oak tree.

Step-by-step explanation:

Given that:

An oak tree grows at a rate of 1.5 feet per year for twelve years;

After 12 year; the oak tree will be = 12 × 1.5 = 18 feet per year.

Now; we are being told that Mostafa plants a maple tree at his backyard and measures its height at 4 feet.

i.e x years  = 4 ft

two years later ; it height is now 6.5 ft

thus;

x year = 4 ft

x + 2 = 6.5 ft

6.5 * x = (x+2)4\\  \\ 6.5 x = 4x + 8\\ \\ 6.5x-4x = 8\\ \\ 2.5x = 8\\ \\ x = \dfrac{8}{2.5}\\ \\ x = 3.2

Thus ; Mostafa first measured the height of the tree when it is 4 ft at the age year of  3.2

So;

if 3.2 year = 4 ft

1 year = x

x  = \dfrac{4 *1 }{3.2}

x  = 1.25 ft

So if an oak tree grows at the rate of 1.5 ft in a year.

Then, Mostafa's maple tree grows at the rate of 1.25 ft in a year.

From the given information in the diagram attached below; we can infer that :

Mostafa's maple tree grows at a slower yearly rate than an oak tree.
