Ghella [55]

Jake puts 6 stamps in his book every day.

30/6= 5

Jake put stamps in the book for 5 days.

So, Dan puts 5 stamps in the book every day.

5*5= 25

Dan has 25 stamps when Jake has 30.

I hope this helps!

Solve the Quadratic Equation By Completing the Square b^2-15b-54=0

vladimir1956 [14]

$b^{2}-15b-54=0. \newline
b^{2}-15b=54. \newline
b^{2}-15b+(\frac{15}{2})^{2}=54+(\frac{15}{2})^{2}. \newline
(b-\frac{15}{2})^{2}=\frac{441}{4}. \newline
b-\frac{15}{2}=\pm\frac{21}{2}. \newline
b=\pm\frac{21}{2}+\frac{15}{2}. \newline
b_1 = -3, b_2 = 18.$

Solve this equation and explain the steps 9-2x= 7x

Hunter-Best [27]

Answer:

x = 1

Step-by-step explanation:

Step 1: Write equation

9 - 2x = 7x

Step 2: Solve for x

Add 2x on both sides: 9 = 9x

Divide both sides by 9: x = 1

Step 3: Check

Plug in x to verify it's a solution.

9 - 2(1) = 7(1)

9 - 2 = 7

7 = 7
