Solve for b.
ab + c = d
Ob = a + c/d
b = a/(c-d)
b = (d - c)/a

Answer:

the relation between angles a and b is that they both add up to 180 degrees. l and m do not seem parallel to me because their corresponding angles do not add up to 180 degrees.

Answer:

Step-by-step explanation:

a)angles a and b are a linear pair

b)no, because in parallel lines alternate exterior angles are always equal but here they are not equal

Answer:

The desired range will be "($ 2.64, $ 13.04)".

Step-by-step explanation:

The query given seems to be missing. Kindly check find the entire questions attachment.

The given values are:

Mean

= $ 7.84

Standard deviation

= $ 2.60

Those are established by empirical rule whether 95% including its values cheat throughout two standard deviations of such the mean, for something like a roughly normal distribution results.

Thus, the range of values which might absorb 95% of all sums will be:

= [tex](Mean - 2\times Standard \deviation, Mean + 2\times Standard \ deviation)[/tex]

On putting the estimated values, we get

= [tex](7.84 - 2\times 2.60, 7.84+ 2\times 2.60)[/tex]

= [tex](7.84-5.2, 7.84+5.2)[/tex]

= [tex]($2.64, $ 13.04)[/tex]

Answer:

2+3 = 5

1/4 + 1/4 = 1/2

5+1/2 = 5 1/2

Step-by-step explanation:

2 1/4 + 3 1/4

Let's break the addition into 2 steps,

Whole number = 2,3

=> 2 + 3 = 5

Fraction = 1/4 , 1/4

=> 1/4 + 1/4 = 2/4 =1/2

Total = 5 1/2

Answer:

  (x, y) = (4, 8)

Step-by-step explanation:

We can multiply the first equation by -8 and the second by +9, then add the result.

  -8(9x -6y) +9(8x -5y) = -8(-12) +9(-8)

  -72x +48y +72x -45y = 96 -72

  3y = 24

  y = 8

Substituting for y in the first equation, we have ...

  9x -6(8) = -12

  9x = 36 . . . . . . add 48

  x = 4

The solution is (x, y) = (4, 8).

Answer:

x = 28

66°

Step-by-step explanation:

[tex] \because \overrightarrow{XZ} [/tex] is the bisector of [tex] \angle WXY[/tex]

[tex] \therefore m\angle WXZ = m\angle ZXY\\

\therefore (2x + 10)\degree = (3x - 18)\degree \\

\therefore 2x + 10 = 3x - 18\\

\therefore 2x - 3x = - 18 - 10\\

\therefore - x = - 28\\

\huge \purple {\boxed {\therefore x = 28}} \\\\

\because m\angle ZXY= (3x - 18)\degree\\

\therefore m\angle ZXY= (3\times 28- 18)\degree\\

\therefore m\angle ZXY= (84- 18)\degree\\

\huge \orange {\boxed {\therefore m\angle ZXY=66\degree}} \\[/tex]

D. The function has no intercepts.

Step-by-step explanation:

There are vertical and horizontal asymptotes on both the x and y-axis (meaning nothing can touch them), so it is impossible for there to be any intercepts.

Answer:

Dana's age = 13 years

Zach's age = 26 years

Jon's age= 18 years

Ella's age = 36 years

Step-by-step explanation:

Let

Dana's age = x

Zach's age = 2x

Jon's age= x + 5

Ella's age = 2(x + 5)

Sum of their age = 93

x + 2x + (x + 5) + 2(x + 5) = 93

x + 2x + x + 5 + 2x + 10 = 93

6x + 15 = 93

Subtract 15 from both sides

6x + 15 - 15 = 93 - 15

6x = 78

Divide both sides by 6

x = 78/6

= 13

Therefore,

Dana's age = x = 13 years

Zach's age = 2x

= 2(13)

= 26 years

Jon's age= x + 5

= 13 + 5

= 18 years

Ella's age = 2(x + 5)

= 2(13+5)

= 26+10

= 36 years

Dana's age = 13 years

Zach's age = 26 years

Jon's age= 18 years

Ella's age = 36 years

Sum of their age = 13 + 26 + 18 + 36

= 93 years

Answer:

a). AB = 8 in

b). AB = 9.75 in

c). AC = 6.5 in

d). BC = 1.5 in

Step-by-step explanation:

a). Since, AB = AC + CB

   Length of AC = 5 in. and CB = 3 in.

   Therefore, AB = 5 + 3 = 8 in.

b). Given : AC = 6.25 in and CB = 3.5 in

   Therefore, AB = AC + CB = 6.25 + 3.5

   AB = 9.75 in.

c). Given: AB = 10.2 in. and BC = 3.7 in.

    AB = AC + BC

    AC = AB - BC

    AC = 10.2 - 3.7

    AC = 6.5 in

d). Given: AB = 4.75 in and AC = 3.25 in.

   BC = AB - AC

   BC = 4.75 - 3.25 = 1.5 in.

Answer:

The oldest age of Olivia’s sister can be 11 years.

Step-by-step explanation:

Given: Olivia’s sister’s age is x years.

To write: inequality that can be used to represent the given situation.

As Olivia is 6 years older than her sister,

Olivia's age [tex]=x+6[/tex]

As the sum of their ages is no more than 28 years,

[tex]x+(x+6)\leq 28\\2x+6\leq 28\\2x\leq 28-6\\2x\leq 22\\x\leq \frac{22}{2}\\ x\leq 11[/tex]

So, the oldest age of Olivia’s sister can be 11 years.

Answer:

1) r = 17

2) n = -10

3) n = 7

4) n = -135

5) x = -1

6) m = -11

7) n = -7

8) x = 5

Step-by-step explanation:

1) To solve for any variable, make sure to isolate the variable

2) Next, make sure to do the same thing you do to one side of the equation the other side, so te equation is in balance

3) Finally, solve for your variable!
