Answer:

x=12

Step-by-step explanation:

16x - (8x + 6) =90

The first step is to distribute the - sign

16x -8x -6 =90

Now we combine the like terms

8x-6 = 90

Add 6 to each side

8x-6+6 = 90+6

8x = 96

Divide each side by 8

8x/8 = 96/8

x =12

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define Systems

-2x + y = 0

5x + 3y = -11

Step 2: Rewrite Systems

-2x + y = 0

Add 2x on both sides: y = 2x

Step 3: Redefine Systems

y = 2x

5x + 3y = -11

Step 4: Solve for x

Substitution

Substitute in y: 5x + 3(2x) = -11
Multiply: 5x + 6x = -11
Combine like terms: 11x = -11
Isolate x: x = -1

Step 5: Solve for y

Define equation: y = 2x
Substitute in x: y = 2(-1)
Multiply: y = -2

Step 6: Graph Systems

Check the solution set.

Bob traveled 90 miles which was 83 1 3 % of his trip. a How long was the trip?

loris [4]

Total journey of bob was 108 miles .

Step-by-step explanation:

Here we have , Bob traveled 90 miles which was 83 1 3 % of his trip. We need to find How long was the trip .Let's find out:

According to question , Bob has traveled a distance of :

⇒ $Distance = 90miles$

Which is $83\frac{1}{3}\%$ of his journey . So , Let total miles be x , So we have following equation framed according to question as :

⇒ $\frac{83\frac{1}{3} x}{100} =90$

⇒ $\frac{83\frac{1}{3} x}{100}(100) =90(100)$

⇒ $\frac{83(3)+1}{3} x=90(100)$

⇒ $\frac{250}{3} x=9000$

⇒ $x=9000(\frac{3}{250} )$

⇒ $x=108miles$

Therefore , Total journey of bob was 108 miles .
