Answer:

x = 5

Step-by-step explanation:

Use the distributive property.

-9x + -72 + 81 = 13 - 10x

Add -72 and 81.

-9x + 8 = 13 - 10x.

Cancel out the -9x

-9x + 9x + 8 = 13 - 10x + 9x.

8 = 13 - x

8 - 13 = 13 - 13 - x

-5 = -x

We can't have a negative x so negate the whole equation.

x = 5

Answer:

740 meters of fence
22,000 square meters

Step-by-step explanation:

Two of the sides total 150 +220 = 370 meters. The other two sides are the same lengths, so the sum of lengths of the four sides is ...

2·370 m = 740 m . . . . . length of fence needed

The area of a parallelogram is the product of base and height.

A = bh = (220 m)(100 m) = 22,000 m^2 . . . . area the fence encloses

Answer:

So, cows heart best is faster than horse.

Step-by-step explanation:

Time and heartbeats are in direct proportion.

p = kx

Where p is the beats per minute and x represents time in minutes

Now, to find the value of k, substitute p = 152 and x = 4

152 = 4k

k = 152/4

k = 38

$\sf \boxed{p = 38x}$

Cow: y = 65x

So, cows heart best is faster than horse

Good evening

Answer:

$x=\frac{-19}{3}$

Step-by-step explanation:

g(x) = -20

⇔

3x-1 = -20

⇔

3x = -20 + 1

⇔

3x = -19

⇔

x = -19/3
