Each side of a regular pentagon is m + 10 inches. The formula for finding the perimeter of the pentagon is shown below. P = 5(m + 10) Which equation shows this formula solved for m? A. m =P − 5 / 10 B. m = 5P − 50 C. m = P − 50 / 5 D. m = P5 − 50

Answers

Answer 1

Answer:

Answer:

Solving for m gives:

$m=(P-50)/(5)$

which is option C in the list of possible answers

Step-by-step explanation:

Starting with the given equation, we work on using distributive property, and then on isolating the term with the variable to express:

$P=5\,(m+10)\nP=5m+50\nP-50=5m\n(P-50)/(5) = m\nm=(P-50)/(5)$

Having troubles with inequalities.. 3.8x + 14.5 < 32

Answers

$3,8x + 14.5 < 32\n 3,8x<32-14,5\n 3,8x<17,5\ /:3,8\n x<(17,5)/(3,8)\n \n 17\frac12 :3\frac45=(35)/(2) :\frac{19}5=\frac{35}2\cdot \frac5{19}\n=(175)/(38)=4(23)/(28)\n x<4(23)/(28)\n x\in (-\infty;4(23)/(28))$

Answer: x < 4.6 rounded to the tenths

Step-by-step explanation:

3.8x + 14.5 < 32

subtract 14.5 on both sides.

3.8x < 17.5

divide by 3.8 on both sides.

x < 4.60526316

When negative five is subtracted from a number the result is 10 find the number15
5
-5
-15

Answers

Answer: second option.

Step-by-step explanation:

Let be "x" the unknown number.

According to the information provided in the exercise, 10 is the result of the subtraction of "x" and -5.

Based on this, you can write the following equation:

$x-(-5)=10$

To find the value of "x" you must remember the multiplication of signs:

$(+)(+)=+\n(-)(-)=+\n(-)(+)=-$

Then:

$x-(-5)=10\n\nx+5=10$

Finally, subtracting 5 from both sides of the equation, you get:

$x+5-(5)=10-(5)\n\nx=5$

Answer:

x - (-5) = 10

x = 5

My final answer is 5
