Answer:

B= 16

b/4 - -1 =5 is the same as b/4 + 1 = 5

b/4 + 1 = 5

- 1 both sides

b/4 = 4

x 4 both sides

b=16

16/4 - -1 =5

4 + 1 = 5

- - Means add

+ + Means add

- + Means take away or minus

Hope this helps!

Plss I need this quickly I don't understand this<br>3(x-6)=6+7

Rufina [12.5K]

Answer:

x = $\frac{31}{3}$

Step-by-step explanation:

Given

3(x - 6) = 6 + 7, that is

3(x - 6) = 13 ← distribute parenthesis on the left side by 3

3x - 18 = 13 ( add 18 to both sides )

3x = 31 ( divide both sides by 3 )

x = $\frac{31}{3}$

The correct answer is: [C]:  " $\frac{7}{18}$ " .
____________________________________________________
Explanation:
____________________________________________________
Given:
____________________________________________________

2 / (9x) = 4 / 7 ; solve for "x" ;
____________________________________________________

Cross-multiply:

→ (9x)*4 = 2 * 7 ;

  → 36x = 14 ;

Divide each side of the equation by "36" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 36x / 36 = 14 / 36 ;

x = 14/ 36 ;

  → x = 14/36 = (14÷2) / (36÷2) = 7/18 ;
______________________________________________________

The answer is: " $\frac{7}{18}$ " ;

→ which is: Answer choice: [C]: " $\frac{7}{18}$ " .
