-1.3n =7.8 need help​
xxMikexx [17]

Hey there!

-1.3n = 7.8

First, you have to DIVIDE both sides by -1.3

-1.3n / -1.3 = 7.8 / -1.3

Cancel out: -1.3 / -1.3 because it gives you the value of 1

Keep: 7.8 / -1.3 because it gives us the value of n

7.8 ÷ -1.3 = -6

Thus, n = -6 ✅

Good luck on your assignment and enjoy your day!

Divide of a right angle into two parts such that the number of English minutes in one to the
stira [4]

Answer:

  • π/3 radians, 3600 English minutes
  • π/6 radians, 333,333 1/3 French seconds

Step-by-step explanation:

An English minute is (1/60)(π/180) radian = π/10800 radian.

A French second is (1/100)(1/100)(π/200) radian = π/2000000 radian.

So, the ratio of angle sizes in common units will be ...

  27(π/10800) : 2500(π/2000000) = (2/800) : (1/800) = 2 : 1

Since the total of these ratio units is 2+1 = 3, we need to divide the right angle into 3 parts. The English part will be 2 of those; the French part will be 1 of them. A 1/3 part of a right angle is π/6 radians, so the right angle division will be ...

  English : French = π/3 radians : π/6 radians

  = 3600 English minutes : 333,333 1/3 French seconds

  = 27 : 2500

Find three consecutive odd integers such that 5 times the third is 94 than the second
IrinaK [193]
------------------------------------------------------------
Define the numbers
------------------------------------------------------------
First the first odd integer be x.
1st odd = x
2nd odd = x + 2
3rd odd = x + 4

------------------------------------------------------------
Form the equation and solve for x
------------------------------------------------------------
5(x + 4) - 94 = x + 2
5x + 20 - 94 = x + 2
5x - 74 = x + 2
5x - x = 2 + 74
4x = 76
x = 19

------------------------------------------------------------
Find the 3 consecutive integers
------------------------------------------------------------
1st = x = 19
2nd = x + 2 = 19 + 2 = 21
3rd = x + 4 = 19 + 4 = 23

------------------------------------------------------------
Answer: The 3 consecutive odd numbers are 19, 21 and 23

Luba_88 [7]

Answer:

$0.20*x + 55$

Step-by-step explanation:

x - is the number of  text messages

Since x the number of text messages it means that to get the amount of money a person will spend will be: $0.20 * x  

And to get the final equation we will just need to add $0.20 + x to $55 =

$0.20 * x + $55
