Answer: Subtituting CD =5 in AB + CD = JK
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
• AB + CD = JK (equation 1 )
• CD = 5 (equation 2)
So, we simply have to combine the equations.
Substituting CD =5 in equation 1:
AB + CD = JK
AB+(5) =JK

Hello. Good?
Formula for calculating two overlapping sets:
A + B - both + not (A or B) = Total
20 (french) + 20 (german) - 10(both) + Not = 50
40 - 10 + not = 50
30 + not = 50
not = 50 - 30
not = 20
Answer: 20 students do not speak french or german.
Thanks, I hope I have helped.
Answer: x = 1
Step-by-step explanation:
5 ( 2x - 8 ) + 15 = -15 (write the equation)
5 ( 2x - 8 ) = -30 (subtract by 15 on both sides)
2x - 8 = -6 (divide by 5 on both sides)
2x = 2 (add 8 to both sides)
x = 1 (divide by 2 on both sides)
You could use change of base formula
