Answer:
30 years old.
Step-by-step explanation:
Here's what we know.
B=5J
M+2=8J+16
M=3B
So now let's solve using substitution.
M+2=8J+16
M=8J+14
But we know that M=3B
3B=8J+14
And we know B=5J
3*5J=8J+14
15J=8J+14
7J=14
J=2
Now, we can plug it into the M+2=8J+16
M+2=2*8 +16
M+2=16+16
M+2=32
M=30

Answer:
{x:x<3}
Step-by-step explanation:
You first change the < to = in order to simply it. Thus,
- 2x-5=1
- 2x=1+5( move the -5 to the right hand side to obtain 5)
- 2x= 6
- dividing through by 2
- 2x/2=6/2
x=3 . Therefore the solution is {x:x<3} <u>sing you didn't divide with a</u> <u>negative number ,the < sing remains unchanged</u>
Answer:
A And D
Step-by-step explanation:
The answer is a because if you divide both sides by 8
you get: m=56/8
Also D because you divide by 5 and you get: x=250/5
What is parallel to 2x+5y=8 is B. I am not sure with D because its actually the same with the given equation.
Hope that helps
