What is 30=-5(6n+6) im confused

Mathematics
1 answer:
Flauer [41]3 years ago
5 0

Answer:

Step-by-step explanation:

30 = -5(6n + 6)...distribute the 5 thru the parenthesis

30 = -30n - 30....add 30 to both sides

30 + 30 = -30n

60 = -30n....divide both sides by -30

-60/30 = n

-2 = n <===

Sam and Bryan meet at the gym. Sam travels 6 miles farther to the gym than Bryan. Three times the distance Bryan travels is 12
Digiron [165]

Answer:

x+6=y and 3x=12

Step-by-step explanation:

Let x be the distance traveled by Bryan and let y be the distance traveled by Sam then the first equation would be:

x+6=y (x plus 6 is equal to y, Bryan's distance plus 6 is equal to Sam's distance) and the second one is:

3x=12 (3 times x is 12, 3 times the distance travelled by Bryan is 12)

So our statements/equations are:

x+6=y and

3x=12 (we dont write this as x=4 as it asks us to give the statements we got from the information given, we only start simplifying once it tells us to solve)

How to solve for x 5x-8=18+4,for x=6
lbvjy [14]
Hey there,

Question : <span>How to solve for x 5x-8=18+4,for x=6

Answer :
5x - 8 = 18 + 4
5(6) - 8 = 18 + 4
30 - 8 = 18 + 4
22   = 22
Thus we can say that 6x = 30
6x = 30 
x = 30 / 6
   = 5

Hope this helps :))

In a right triangle ABC angle B is the right angle and m angle C = 30 degrees if AC = 10 what is AB
Sindrei [870]

Answer:

  • AB = 5

Step-by-step explanation:

This is a 30°-60°-90° right triangle.

AC is hypotenuse, AB is opposite side to 30° angle.

We know that in such a triangle the side opposite to 30° angle is half the hypotenuse.

<u>So we have:</u>

  • AB = 1/2AC = 1/2(10) = 5
