this is because the two numerals are the same only one is negative so they cancel out and equal 0

Answer:

The answer is 0

Step-by-step explanation:

The answer is 0 because -9+9 is just like putting 9-9.

Hope this helps!!

Answer:

The two equations are

r = 600m

and

r/600 = m

Step-by-step explanation:

Here, we want to write equations

The equation is;

r(m) = 600m

where r is the amount spent and m is the number of months

r = 600m

and r/600 = m

Answer: -4.5 ℉

Step-by-step explanation:

Given: On the coldest day of the year, the temperature at noon = 11℉

By midnight, the temperature had decreased by 15.5℉.

i.e. The temperature at midnight = Temperature at noon - 15.5℉

= 11℉ - 15.5℉

= (11-15) ℉

= -4.5 ℉

Hence, the temperature at midnight was -4.5 ℉.

Answer:

The answer is that 8-5 can not be simplified as well as 8-3

Step-by-step explanation:

Answer: p = 120 degrees

Step-by-step explanation:

Figure a shows a pentagon. The sum of interior angles in a pentagon is equal to 540 degrees.

1. Subtract the known numerical angle

540 - 60 = 480

All of the remaining angles (represented by the variable p) are equal to one another. Therefore, we can use the expression 4p = 480 to find the value of p.

2. Evaluate the equation to find the value of p.

4p = 480

p = 120

Answer:

± 5.919

Step-by-step explanation:

Margin of Error formula = z × standard deviation/√n

Z score for 99% confidence interval = 2.58

n = 19

Standard deviation = 10

Margin of Error = 2.58 × 10/√19

= ± 5.9189259339

Approximately to 3 decimal place = ± 5.919

Given :

C) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm.

There exist two circles of center A and tangent to (C).

To Find :

The radius of the new circles.

Solution :

Since, OA is 3 cm .

So, first circle with tangent to C if centre is at A is OA itself.

First radius, r = 3 cm.

And second circle is the on with radius , R = 3 + 2 = 5 cm.

Therefore, the radius of both the circles are 3 cm and 5 cm.

Hence, this is the required solution.

Answer: the answer is 21

Answer:

x = 2

Step-by-step explanation:

3(4x-6) -2x + 1 = 3 - (3x -6)

12x-18 -2x + 1 = 3-3x + 6

10x-17 = -3x+9

    +17         +17

10x = -3x + 26

+3x    +3x

13x = 26

/13    /13

x = 2
