Solve the equation: 3 - 2/9b = 1/3b - 7

aleksandrvk [35]

3 - $\frac{3}{9} b$ = $\frac{1}{3} b$ - 7

First, simplify $\frac{2}{9} b$ to $\frac{2b}{9}$ / Your problem should look like: 3 - $\frac{2b}{9}$ = $\frac{1}{3} b$ - 7
Second, simplify $\frac{1}{3} b$ to $\frac{b}{3}$ / Your problem should look like: 3 - $\frac{2b}{9}$ = $\frac{b}{3}$ - 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like: $\frac{90}{5}$ = b
Ninth, simplify $\frac{90}{5}$ to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18

Answer: b = 18

Find the missing value of the sides.

umka2103 [35]

Answer:

The values for both of the missing sides is 8.

Step-by-step explanation:

The hypotenuse of a right triangle = a(square root of 2)

Therefore the other two missing sides equal a.

Therefore, the other two sides equal 8.

Explain how to solve the equation 2x+4=-6x+38 in complete sentences. Your response needs to be a paragraph in length and use app

icang [17]

Answer:

×=17/4

Step-by-step explanation:

The equation 2x+ 4=-6x+38

First of all you collect like terms by moving the number -6x over to the left hand side which then becomes +6x as it crosses the equal to sign, likewise you move +4 over to the right hand side which then becomes -4. The equation is now 2x+6x=38-4, which when solved gives 8x=34. X is then made subject of formula by dividing both sides by 8 therefore x=34/8 which when reduced to the lowest term is 17/4

I hope it helps
