Write (2x10) + (9 x 1) + (7 x 0.10 ) + (8 x 0.001) in standard form.

7x+4=3x-20

Subtract 3x to the left.

4x+4=-20

Subtract 4 to the right.

4x=-24

Divide -24/4 to isolate variable "x".

x=-6

Plug it back it to prove the solution.

7(-6)+4=3(-6)-20

-38=-38

Answer:

7x+3=-25+3x

minus 3 on both sides

7x=-28+3x

minus 3x both sides

4x=-28

divide 4 both sides

x=-7

the number is -7

Answer:

565.5 in²

Step-by-step explanation:

Lateral area of a cone is represented by,

Lateral surface area = πrl

Here 'r' = Radius of the circular base

l = lateral height of the cone

By this formula,

Lateral area = π(12)(15)

                    = 565.49

                    ≈ 565.5 square inch

Therefore, 565.5 in² is the answer.

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line is y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope of the line using the points (1, 1) and (2, 4).

Slope = [tex]\frac{rise}{run}[/tex]

          = [tex]\frac{4-1}{2-1}[/tex]

          = 3

Based on the graph, the y-intercept is (-2) so the equation of the line is:

y = 3x - 2

Answer:

v = -5

Step-by-step explanation:

to get v by itself, you must subtract 3 from both sides, not only to cancel out the positive 3 but to keep both sides equal. this leads to -5 = v so that's your answer.

Answer:

Your answer is: [tex]V= -5[/tex]

Solve for  v  by simplifying both sides of the equation, then isolating the variable.

Answer:

[tex]900m^3[/tex]

Step-by-step explanation:

Volume is found when you multiply length by height by width.

So, in this case, 18 times 10 times 5.

[tex]18*10*5=180*5=900[/tex]

So, [tex]900m^3[/tex] is the answer

Answer:

x < 3

Step-by-step explanation:

3x - 2x - 2 < 1

3x - 2x < 1 + 2

x < 1 + 2

x < 3

Answer:

The answer is A.

Step by step explanation

x²-1

Where

Roots (-1,0) (1,0)

Domain x€R

Range f(x)€ [-1,+infinity]

Minimum (0,-1)

Vertical intercept (0,-1)

Answer: There are 57 quarters and 33 dimes.

Step-by-step explanation:

let x = Number of quarters

y= Number of dimes

As per given , we have

x+y = 90  (i)

0.25x+0.10y= 17.55  (ii)

Multiply 10 on both sides of (ii)

2.5x+y= 175.5    (iii)

Eliminate (i) from (iii) , we get

1.5x = 85.5

⇒ x= 57

Put value of x in (i) , we get

57+y=90

⇒  y= 90-57

⇒  y= 33

Hence, there are 57 quarters and 33 dimes.

Answer:

x = 3

Work below

Step-by-step explanation:

5x + 12 = 27

-12. -12

5x = 15

/5 /5

x = 3

Hope this helps!!

Answer:

3

Step-by-step explanation:

5x+12=27

subtract 12 from 12 and 27 to cancel the 12 you wan your number that has a letter by its self 12-12=0 12-27=15 then you divide what ever number that has a number by whatever number your left with so 15/5=3

Answer: perimeter

Step-by-step explanation:

Answer:

Step-by-step explanation:

(-1-1)/(8-0)= -2/8= -1/4

y + 1 = -1/4(x - 8)

y + 1 = -1/4x + 2

y = -1/4x + 1

Answer:

The quotient is  3 and [tex]\frac{3}{4}[/tex].

Step-by-step explanation:

To find the quotient of the division (which is just the solution, really), we have to solve the division itself:

[tex]\frac{\frac{3}{4}}{\frac{1}{5}}[/tex]

[tex]= \frac{3 \cdot 5}{1 \cdot 4}[/tex]

[tex]= \frac{15}{4}[/tex]

Now that we know the quotient, we can look at the question itself to find it requires from us an answer with a whole number in it.

Therefore, we transform the fraction as thus:

[tex]\frac{15}{4}[/tex]

[tex]= 3 \frac{3}{4}[/tex]

Therefore, the final answer is 3 and [tex]\frac{3}{4}[/tex].

Answer:

The cost of a gym membership would be 109

Step-by-step explanation:

2009-1995=14

thats how many years apart from each other

so its been 14 years $6 for each year so 14x6=84

so the regular price was $25 and went up 84 dollars last 14 years.

25+84=109 so the price of gym membership would be $109

Answer:

The area of a shape is the amount of two-dimensional space that it covers. The ratio of the perimeter to the area of a shape is simply the perimeter divided by the area. This is easily calculated.

Answer:

True

Step-by-step explanation:

-10×5+5=-9×5

-45=-45

So it's 100% true

Because -45 is equal to -45
