Answer: 27
Step-by-step explanation:
2/3x-7=11
2/3x=18
1/3x=9
x=27
Here's how you solve this. So, x+y=2, right? Let's isolate x. x+y-y=2-y. x=2-y. NOW, if x=2-y, in 3x+2y=5, we can REPLACE x with 2-y and use it to solve for y! 3x+2y=5. 3(2-y)+2y=5. (3*2)+(3*-y)+2y=5. 6+(-3y)+2y=5. 6+(-y)=5. 6+(-y)-6=5-6. -y=-1. -y/-1=-1/-1. y=1.
So, if y=1, we can substitute that back into either equation--but let's go with the easier one, x+y=2. x+1=2. x+1-1=2-1. x=1. 1+1=2, so that works; let's check the other equation. 3(1)+2(1)=5. 3+2=5. 5=5. That's correct!
Answer: x=1, y=1
Answer:
its G. and J
Step-by-step explanation:
<span>First, the formula would be like this dP / dt= KP.
Secondly, since dP is given which is 6.9. Substitute it from the equation.
P(0) = 6.9 x 10^6
integral 1 divided by pdp which will look like this,
integral 1/ PdP = integral kdt
the answer would be .0019 or
k=.0019</span>
I think But I'm not 100% sure yet it's a guess
Y=3+x
Root: (-3, 0)
Intercept:(0, 3)
