Answer:

x = 3.9

Step-by-step explanation:

5(2x-3)=24

Distribute

10x -15 = 24

Add 15 to each side

10x-15+15 = 24+15

10x = 39

Divide each side by 10

10x/10 = 39/10

x = 3.9

Subtract -6x^4-3x^2y^2+5y^4−6x

Gnoma [55]

Answer:

$8x^4-5x^2y^2-6y^4+6x$

Step-by-step explanation:

We are required to subtract $-6x^4-3x^2y^2+5y^4-6x \:from \: 2x^4-8x^2y^2-y^4$ .

$[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]$

Step 1: Open the bracket, Take note of the signs

$[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]\\2x^4-8x^2y^2-y^4+6x^4+3x^2y^2-5y^4+6x$

Step 2: Collect like terms

$2x^4+6x^4-8x^2y^2+3x^2y^2-y^4-5y^4+6x$

Step 3: Simplify

$8x^4-5x^2y^2-6y^4+6x$

The lizards in the show eats about 200 crickets per week.About how many crickets do they eat each day.

bogdanovich [222]

Since there are 7 days in a week, you divide 200 and 7 to get 28.57.

You must also round to the nearest integer, so the lizards in the shows eat about 29 crickets each day.
