Answer:

5. k=−3

6. x=4

7. n=−108

Step-by-step explanation:

5. -14k+29=71

Subtract 29 from both sides

-14k+29-29=71-29

Simplify

-14k=42

Divide both sides by -11

-14k/-14=42/-14

6. -33=19-13x

Subtract 29 from both sides

-14k+29-29=71-29

Simplify

-14k=42

Divide both sides by -14

-14k/-14=42/-14

Simplify

k=-3

7. 8+n/25=-4

Multiply both sides by 25

25(8+n)/25 = 25 (-4)

Simplify

8+n=-100

Subtract 8 from both sides

8+n-8=-100-8

Simplify

n=-108

Explain why 30 divided by x = 6 is the same as 30 -x-x-x-x-x-x

dem82 [27]

Answer:

See below.

Step-by-step explanation:

The expression 30 / x is the same as 30 -x - x - x - x - x because division is repeated subtraction. Division divides a number into a specified number of group sizes. 30 / x where x = 6 means divide 30 into 6 groups. Within each group will be 5.

The expression 30 - x -x -x -x-x-x has 6 groups of x where each group is size 5.

MO bisects angle LMN , angle LMO = 6x-22 and angle NMO = 2x +34. Solve for x and find angle LMN.

Mkey [24]

Answer:

$x=14$

$\angle{LMN}=124\textdegree$

Step-by-step explanation:

To Determine:

Solve for x and find angle LMN.

Fetching Information and Solution Steps:

Considering the angle $\angle{LMN}$

As MO bisects the angle $\angle{LMN}$ into two equal angle parts. These equal angles are:

$\angle{LMO}=6x-22$

$\angle{NMO}=2x+34$

As these angles are equal. i.e.

$\angle{LMO}=\angle{NMO}$

$6x-22=2x+34$

$\mathrm{Add\:}22\mathrm{\:to\:both\:sides}$

$6x-22+22=2x+34+22$

$6x=2x+56$

$\mathrm{Subtract\:}2x\mathrm{\:from\:both\:sides}$

$6x-2x=2x+56-2x$

$4x=56$

$\mathrm{Divide\:both\:sides\:by\:}4$

$\frac{4x}{4}=\frac{56}{4}$

$\mathrm{Simplify}$

$x=14$

Hence, $x=14$

As $\angle{LMN}$ was cut into two equal parts $\angle{LMO}$ and $\angle{NMO}$

So,

$\angle{LMN}$ = $\angle{LMO} + \angle{NMO}$

= $6x-22+2x+34$

= $8x + 12$

= $8(14) + 12$ ∵ $x=14$

= $124\textdegree$

Therefore, $\angle{LMN}=124\textdegree$

BRAINLIEST ANSWER! PLEASE HELP! -2x-10x+12=18 PLEASE EXPLAIN HOW YOU GOT THE ANSWER

vagabundo [1.1K]

Answer:

x = - 0.5

Step-by-step explanation:

you have to simplify the equation so

$- 2x - 10x + 12 = 18 \\ - 12x + 12 = 18 \\ - 12x = 18 - 12 \\ - 12x = 6 \\ x = \frac{6}{ - 12} \\ x = - 0.5$
