Answer:

The first equation; x-2y=8

Step-by-step explanation:

Hi there!

We're told that Ty wants to isolate x in one of the equations. To do so in either, he will need to use inverse operations to cancel out values and leave just x remaining on one side of the equation.

In the second equation, he would need to subtract both sides by 6y and then divide both sides by 4 to isolate x. It's a two-step process.

However, in the first equation, he only needs to add 2y to both sides to isolate x.

I hope this helps!

Answer:

using the first equation

cause Being that the first equation has the simplest coefficients (1, -2, for x, and y respectively), it seems logical to use it to develop a definition of one variable in terms of the other

A person that weighs 179 lbs needs an IV Drip in mL. The drug only comes in powder form but can be converted as 10 mg is equal t
OleMash [197]

Solution:

Weight of person = 179 lbs

As given person needs IV Drip in m L.

Also,→ 10 mg = 2 m L

Now, you must remember , → 1 lbs = 0.453 Kg (approx)

→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)

The person needs at least 60 mg for each Kg they weigh.

⇒ 1 Kg → 60 mg

⇒ 78.47 × 1 Kg → 78.47 × 60 mg

⇒ 78.47 Kg →  4708.2 mg

Also, 10 mg → 2 m L

⇒ 1 mg → \frac{1}{5}  m L

⇒ 4708 . 2 mg → \frac{1}{5} \times 4708.2  m L

⇒ 4708 . 2 mg → 941. 64 ml

Serjik [45]

Answer:

Perimeter = 15 cm

Step-by-step explanation:

The equation P=5s represents the perimeter P of a regular pentagon with side length s.

We need to find the perimeter of a regular pentagon with side length of 3 cm.

To find it, put s = 3 cm in the given equation.

P = 5(3) cm

= 15 cm

Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.
