Answer:

$-20=16$

Step-by-step explanation:

Given the following equation:

$4(-5)=8+8$

Due to the equation having no variable we do not have to solve for anything, but we can simplify.

$4(-5)=8+8$

$4(-5)=4\times-5=-20$

$8+8=16$

$-20=16$

Hope this helps.

Novosadov [1.4K]

Answer:

$\frac{3}{4} \geq \frac{k}{-8}$
k ≥ -6

Step-by-step explanation:

Re-arrange: $\frac{3}{4} \geq \frac{k}{-8}$
Multiply each side by -8 to cancel out the -8 under k. It should now look like this: k ≥ -6

Turtles can live a long time. This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalam

madreJ [45]

Answer:

1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67

The average age is 22 yrs

The sum of the ages is 440 yrs

When two of the turtles leave, the average is 21 yrs....and there are 18 turtles left

So....the sum of the ages is 21 * 18 = 378

And the difference in the sums is 62

The only two values that sum to 62 are 26 and 36

So.....the box turtle must have been 36 and the map turtle must have been 26

$7.74 \: {cm}^{2}$

Step-by-step explanation:

Area of the green shaded part

= Area of square with side 6 cm - Area of circle with radius (6/2=3) 3 cm.

$= {side}^{2} - \pi {r}^{2} \\ = {6}^{2} - 3.14 \times {3}^{2} \\ = 36 - 28.26 \\ = 7.74 \: {cm}^{2}$
