What is the number sequence for 7, 16,8,27, 9, ?

1 answer:

3 0

The number next to 9 is 40. In this question, numbers 7, 8, and 9 have intervals of 1. In order to get the sequence for 16 and 27, you have to use the following formula: 7 plus 1 is equals to 8 multiply it by 2 = 16. For number 27, 8 plus 1 is equals to 9 multiplied by 3 = 27. Next would be 9 plus 1 equals to 10 multiplied by 4 to come up to 40. Hope this answer helps.

This is a proportion. What is the value of X?

Verizon [17]

Answer:

x = 15 or x = - $\frac{2}{5}$

Step-by-step explanation:

Cross- multiplying gives

(14x + 6)(17x + 5) = 9x(27x + 11) ( expanding factors )

238x² + 172x + 30 = 243x² + 99x

rearrange into standard form : ax² + bx + c = 0

5x² - 73x - 30 = 0 ← in standard form

consider the factors of the product 5 × - 30 = - 150 which sum to the coefficient of the x-term (- 73 )

the factors are - 75 and + 2

Use these factors to split the middle term

5x² - 75x + 2x - 30 = 0 ( factor by grouping )

5x(x - 15) + 2(x - 15) = 0 ← take out the factor (x - 15)

(x - 15)(5x + 2) = 0

equate each factor to zero and solve for x

x - 15 = 0 ⇒ x = 15

5x + 2 = 0 ⇒ x = - $\frac{2}{5}$

6) Solve. x + 5 = 10 A) x = 2 B) x = 3 09 x = 4 D) X = 5

D is the correct answer
x+5=10: subtract 5 from both sides the 5 will cancel out leaving x=5
x+5=10
-5 -5
x=5
