Answer:
Its -2
Step-by-step explanation:
Let's solve your equation step-by-step.
−12−4x+3=−1
Step 1: Simplify both sides of the equation.
−12−4x+3=−1
−12+−4x+3=−1
(−4x)+(−12+3)=−1(Combine Like Terms)
−4x+−9=−1
−4x−9=−1
Step 2: Add 9 to both sides.
−4x−9+9=−1+9
−4x=8
Step 3: Divide both sides by -4.
−4x
−4
=
8
−4
x=−2
Answer: First add 5 to both sides
Answer:
angle l = 115
angle k = 115
angle j = 114
angle i = 66
Step-by-step explanation:
angle l = it is opposite to 115 so its the same
angle k = opposite opposing angles with angle l
angle j = 180-66=114 (between 2 parallel lines the sum of 2 angles is 180)
andle i = 180-114=66 (straight line = 180 degrees so subtract angle j to get i)
10C4 represent the Combinations of 10 objects taken 4 at a time.
The formula for nCr is:

In the given case, n=10 and r=4. Using these values we get:

This means we can make 210 combinations of 10 objects taken 4 at a time.
For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16
21d = 42
d = 42/21
d = 2 :)))
I hope this is helpful
have a nice day
