Answer:

A

Step-by-step explanation:

Given

\sqrt{qrv+11} = 30 ( square both sides to clear the radical )

qrv + 11 = 900 ( subtract 11 from both sides )

qrv = 889 ( divide both sides by rv )

q = \frac{889}{rv} → A

Which of the following statements is true?
IrinaVladis [17]

Answer:

option C is correct.

Step-by-step explanation:

Checking equation A

(9x^3 + 12x) + (16x^3 -4x+1)= 24x^3 +16x-1\\9x^3+16x^3+12x-4x+1=24x^3+16x-1\\25x^3+8x+1\neq 24x^3+16x-1

Checking equation B

(3x+2x^2-4)-(x^2+x-5)=2x+x^2-9\\3x-x+2x^2-x^2-4+5=2x+x^2-9\\2x+x^2+1\neq 2x+x^2-9

Checking equation C

(10x^3+2x^2-11)+(9x^2+2x-2)=10x^3+11x^2+2x-13\\10x^3+2x^2+9x^2+2x-11-2=10x^3+11x^2+2x-13\\10x^3+11x^2+2x-13=10x^3+11x^2+2x-13

Checking equation D

(-7x^2+12)-(5-4x^2)=11x^2-17\\-7x^2+4x^2+12-5=11x^2-17\\-3x^2+7\neq 11x^2-17

Hence, only option C is correct.

Find the least common denominator for these fractions. Enter your answer in
Tju [1.3M]

Answer:

LCD = 12

Equivalent Fractions with the LCD

5/6 = 10/12

5/4 = 15/12

Step-by-step explanation:

Rewriting input as fractions if necessary:

5/6, 5/4

For the denominators (6, 4) the least common multiple (LCM) is 12.

LCM(6, 4)

Therefore, the least common denominator (LCD) is 12.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

5/6 = 5/6 × 2/2 = 10/12

5/4 = 5/4 × 3/3 = 15/12

I used a least common denominator calculator so I hope this helped!!

Sliva [168]

Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle

Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.

The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
