7.1 is the correct answer. the closer the number is to the whole number is the correct answer.
15.5 rounded to the nearest tenth is 15.5
Answer:
Option D. is correct.
Step-by-step explanation:
Let us assume that x = seven square root three plus two square root nine
i.e. x = 7√3 + 2√9
⇒ x = 7√3 + 2 × 3 {Since 9 = 3²}
⇒ x = 7√3 + 6
Here, 7√3 is an irrational number and 6 is a rational number.
The answer is seven square root of three plus six is irrational because the sum of a rational number and an irrational number is an irrational number.
Therefore, option D. is correct.
Answer:
f(4) = -18
Step-by-step explanation:
f(x) = -5x + 2
f(4) = -5(4) + 2 = -20 + 2 = -18
The value of p is 5.
<u>Step-by-step explanation</u>:
<u>step 1</u> : The given expression is -6( p -5 )
<u>step 2</u> : To find any unknown value in an expression, equate it to zero.
<u>step 3</u> : -6( p -5 ) = 0
<u>step 4</u> : Multiply -6 to each term in the bracket.
-6p + 30 = 0
-6p = -30
p = -30/-6
p = 5
