Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:
x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−12=−4x+23
Step 1: Add 4x to both sides.
3x−12+4x=−4x+23+4x
7x−12=23
Step 2: Add 12 to both sides.
7x−12+12=23+12
7x=35
Step 3: Divide both sides by 7.
7x
7
=
35
7
x=5
Answer:
x=5
Answer:
200
Step-by-step explanation:
the above is an arithmetic progressions
number of terms of an AP = a+( n -1 )d
a= first term= 8
d= common difference= 12-8= 4
49th term:
= 8+(49-1)4
= 8+(48)4
= 8+192= 200
therefore, the 49th term is 200
All of the telephones * all of the telephones minus one (because one is in use)
85 * 84 = 7140 connections
The discounted clock would be 6 dollars. I found this by creating a table with 3/3, 2/3, and 1/3 on one side and the 18 across from 3/3 since it is the regular price. To find 2/3 I think we should find 1/3 first. To find that we simply divide 18 by 3 since we are finding one third of 18. Luckily 3 evenly goes into 18 6 times. Now we aren’t done, that is 1/3 so we double the 1/3 which is 2/3 and we double the 6 which is 12. Now that we know how much those cost, it says 2/3 off. The regular price was 18 and 2/3 was 12 so 18-2/3 is 18-12 which equals 6. The discounted alarm clock is $6.00.
Answer:
60
Step-by-step explanation:
Angles 1 and 2 are supplementary, which means that their sum is 180 degrees.
180 - 120 = 60
Angle 1 is 60 degrees
