Answer:
A, c(excluding tip, if the tip is included then c is not the answer)
Step-by-step explanation:
I solved the Equations:
A)1/8(x+16)=76/8----60 (this is the correct answer!)
B)1/8(x+16=76)------ 592 (NOT the correct answer
c)x=60 Represents total food bill excluding tip
d) x=60 does represent each friends share of the food bill
E) not correct
Exact value of x will be 8 x sin(60)
Exact value of sin 60 = √3/2
So √3/2 x 8= 8 √3/2
Can be simplified to 4 √3
Answer:
Step-by-step explanation:
x+6/11=10/11
This is a linear equation, because x has no power, so it will be solved by making x the subject of the equation.
Make x the subject
x+6/11=10/11
x=-6/11+10/11
x=10/11-6/11
Since both fractions have the same denominator, the LCM remains 11
x=(10-6)/11
x=4/11
To check if the answer is correct, we substitute x for 4/11 in the equation. And both sides of the equation must be equal
x+6/11=10/11
4/11+6/11=10/11
(4+6)/11=10/11
10/11=10/11
