Find the mistake made in the steps to solve the equation below.
61 - 1 = -25 +9
85 - 1=9
1. addition property of equality
85 = 10 2. addition property of equality
3. division property of equality
4. simplification

step 2 is incorrect and should be 85 = 8
the justification for step 2 is incorrect and should be the subtraction profy of equality,
the justification for step 3 is incorrect and should be the multiplication property of equality
step 3 is incorrect and should be s = 10

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

the answer is 2/54

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
