Hey there! :D
$43 dinner with 18% tip.
18%=.18
.18*43= 7.74
43+7.74= 50.74
The meal would cost $50.74.
I hope this helps!

Since you are given a list of choices, you can go through each choice to plug them into the equations. It turns out that choice B is the answer
(3,1) means that a = 3 and b = 1
Plug in a = 3 and b = 1 into the first equation
2a - 5b = 1
2*3 - 5*1 = 1.... replace 'a' with 3, replace b with 1
6 - 5 = 1
1 = 1
we get a true equation, so we have confirmed the first equation
Do the same for the second equation
3a+5b = 14
3*3+5*1 = 14 .... replace 'a' with 3, replace b with 1
9+5 = 14
14 = 14
we get a true equation, so the second equation has been confirmed
Both equations are true when (a,b) = (3,1). So the answer (3,1) has been confirmed fully
Answer:
There isn’t a solution to this when using substitution or elimination.
Step-by-step explanation:
We have that F is proportional to m1. Hence, we have that F=m1*c when we change the first mass. We also have that F=m2*c when we only change the 2nd mass. Since F scales inversely with the square of the distance, we have that
. Combining all of the facts above, we get that F=c*
where c is a constant.
x < −8/21
