Answer:

  x = -1

Step-by-step explanation:

Putting the entire equation in decimal form, we have ...

  2.1x + 1.8 = 0.3x

Subtracting 0.3x gives ...

  1.8x +1.8 = 0

Dividing by 1.8, we get ...

  x + 1 = 0

So, the solution is ...

  x = -1 . . . . . . subtract 1 from both sides.

_____

Additional comment

Sometimes, when all of the numbers in the equation are divisible by the coefficient of x, it works out well to do that division before separating variables and constants. The other way this could have been solved is ...

  subtract 1.8  ⇒  1.8x = -1.8

  divide by 1.8  ⇒   x = -1

Answer:

Hi i am sorry but i can not seem to open the picture it say that there is not a file

Step-by-step explanation:

Answer:

x-intercepts -1, 5.

Vertex is at (2, -9).

Step-by-step explanation:

y = x^2 - 4x - 5

Completing the square:

y = (x - 2)^2 - 2^2 - 5

y = (x - 2)^2 - 9   which is vertex form.

So the coordinate of the vertex are (2, -9).

Finding the x-intercepts:

(x - 2)^2 - 9 = 0

(x - 2)^2 = 9

x - 2 = +/- 3

x =  3 + 2  or -3+2

= 5, -1.

B is the correct answer

we need more stuff sorry but we can't awnsers it doesn't give enough instructions but from that I would say incorrect

Answer:

She is correct

Answer:

SRQ=24°

QTS=30°

RST=60°

RSQ=30°

Step-by-step explanation:

All angles in a triangle will always=180.

First we will find RQT

30+24+Q=180

Subtract 54 from each side

Q=126

Since All lines meet in the middle at Q, then each if those angle measures are equal.

We'll find SRQ first:

We don't know S but we know R is 24 and Q is 126

126+24+S=180

subtract 150

S=30°

QTS:

It tells us that T is 70° so that's all we need for this

RST:

We found half of S which was 30, so 30•2= 60 so RST=60

RSQ:

We already found the half of S which was 30°

Given:

Volume of a cube = 1.5 m³

To find:

The length of its edge to the nearest tenth of a meter.

Solution:

Let a be the length of its edge.

We know that, volume of a cube is

[tex]V=a^3[/tex]

where, a is edge.

Volume of a cube = 1.5 m³

[tex]a^3=1.5[/tex]

Taking cube root on both sides, we get

[tex]a=\sqrt[3]{1.5}[/tex]

[tex]a=1.14471424[/tex]

Approximate the value to the nearest tenth (one decimal place) of a meter.

[tex]a\approx 1.1[/tex]

Therefore, the length of the edge of the cube is about 1.1 meters.

Answer:

6.98

Step-by-step explanation:

The answer would be 6.98 after subtracting 8.92 from the 15.9 after applying arithmetic operation.

The study of numbers and their operations, which are relevant to all other fields of mathematics, is part of the discipline of arithmetic operations. Addition, subtraction, multiplication, and division are the basic operations that make up this system.

It is given that:

The number expression is:

= 15.9-8.92

As we know from the definition of the arithmetic operation: Addition, subtraction, multiplication, and division are the basic operations that make up this system.

In the expression subtract 8.92 from the 15.9

After applying the arithmetic operation:

= 6.98

Thus, the answer would be 6.98 after subtracting 8.92 from the 15.9 after applying the arithmetic operation.

Answer: It took Sandy 11 hours to travel the same distance that Sam took 5 hours. {{{R[s]*11=5*75}}}

{{{R[s]=(5/11)*75}}}

{{{R[s]=34.9}}}{{{mph}}}

Don't ask sometimes i don't make sense...

The final answer is 11 hours... Hope this helps... Stay safe and have a great weekend!!! :D

Answer:

68 1/3

Step-by-step explanation:

Going 82 mph faster for 5 hours, Mary closed a (82 mi/h)×(5 h) = 410 mile gap. That gap was created in 3 hours by Sandy going.

 (410 mi)/(6 h) = 68 1/3 mi/h

Answer:

a) $19.5

b) Next = Now + 19.5

c) y = 19.5x+24.5

Step-by-step explanation:

m=y2-y1/x2-x1

m=83-24.5/4-1

m=58.5/3

m=19.5

b) Next = Now + 19.5

c) y = 19.5x+24.5

Answer:

$8.51

Step-by-step explanation:

3.85*.5=1.925

2.25*4.25=9.5625

20-1.925-9.5625=8.5125

Rounding down, Mike will have $8.51 left over. I am not sure how your teacher likes to handle rounding.

Answer:

x=19

Step-by-step explanation:

Basic Algebra.

x - 13 = 6

Simply move the 13 to the right side.

This involves changing the sign to positive, due to it being a negative integer.

The resulting outcome is

x = 13+6

Which concludes to

x=19

Answer:

-8

Step-by-step explanation:

Turn the equation into slope intercept form [ y = mx + b ]

y + 11 = 2(x + 1.5)

~Distribute right side

y + 11 = 2x + 3

~Subtract 11 to both sides

y = 2x - 8

"b" represents the y-intercept, so, the y-intercept is -8.

Best of Luck!

Answer:

I will answer in English.

Here, we want to find all the 3-digit multiples of 5, that can be formed with the digits:

a) 5, 7, and 8. (i suppose that we can not repeat the digits)

First, we know that all the multiples of 5 end with a 5 or a 0, then the possible ones here are:

875

785

(the five must always be at the end)

b) 0, 3, and 5.

Now we have two options, if the 5 is at the end, we have:

305

(035 is not an option, because is a 2-digit number).

if 0 is at the end, we have:

350

530
