(5x+6) over 2 = 3 (4x+12)

Answers

Answer 1
Answer:

x= -66/19

Multiply 2 on both sides:

2*(5x+6)/2=3(4x+12)*2

Simplify:

5x+6=24x+72

Subtract 6 from both sides:

5x+6-6=24x+72-6

Simplify:

5x=24x+66

Subtract 24x from both sides:

5x-24x=24x+66-24x

Simplify:

-19x=66

Divide both sides by -19

-19x/-19=66/-19

Simplify:

x= -66/19

Which choice is equivalent to the quotient shown here when x > 0?√72x^3 divide by square root of 50x^2

Answers

Answer:

(3√(2x))/(5)

Step-by-step explanation:

Starting point:

(√(72x^3))/(50x^2)\n

1) Factor it by Prime Factor Method 72 and 50

72|2\n 36|2\n 18|2\n 9|3\n3|3\n 1\n 72=2^2*3^2*2

50|2\n 25|5\n 5|5\n 1\n 50=2*5^2

2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.

(√(72x^2*x))/(50x^2)=(6x√(2x))/(5x√(2))=(6√(x))/(5√(2))

3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.

(6√(x))/(5√(2))*(√(2))/(√(2))=(6√(2x))/(10)=(3√(2x))/(5)

For safety, each climber has 8 88 hooks when climbing the mountain. a large group of climbers climbs up a mountain and puts all their supplies in a heap in a cabin. one of the climbers wishes to know the number of climbers in the group, so he counts the number of hooks in the supply heap. if the climber counts h hh hooks, which of the following functions can be used to find the number of climbers, c ( h ) c(h)c, left parenthesis, h, right parenthesis, in the group?

Answers

c(h) = h/8 The answer to the question posed is that a function c(h) = h/8 can be used to find the number of climbers, c(h), in the group.
