The vertex angle of an isosceles triangle is 20° less than the sum of the base angles. Which system of equations can be used to
WINSTONCH [101]

The answer to the above question can be explained as under -

We know that, the sum of angles of triangle is 180°.

So, vertex angle plus base angles are equal are equal to 180°.

Let the vertex angle be represented by "v" and base angles be represented by "b".

Thus,  v + b + b = 180°

So,  v + 2b = 180°

Next, the question says, the vertex angle is 20° less than the sum of base angles.

Thus, 2b - 20° = v

<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>

Six yards of rope costs $5.50 while four yards costs $4.75
Amiraneli [1.4K]

The best option is the first one (Six yards of rope costs $5.50). It is the lowest unit cost.

<u>Step-by-step explanation:</u>

For the given question case, first we should compare the unit costs of the choices provided and evaluate the best option.

Choice 1:

Six yards of rope costs $ 5.50

            \frac{5.50 \text { dollar}}{6 \text { yard }}=0.9167\ dollar/yard

Choice 2:

Four yards costs $ 4.75

           \frac{4.75 \text { dollar}}{4 \text { yard }}=1.1875\ dollar/yard

Thus, the best choice is the first one. Because it is the lowest unit cost.

I need the answers to these if you can’t read it it says “You drink 16 Fluid ounces of milk for breakfast every morning”.
Reika [66]

Answer: A. y = 16 x

B. 8 days

Step-by-step explanation:

A) Here, 16 Fluid ounces of milk is used for breakfast every morning.

In one day the consumption of milk = 16 fluid ounces

In x days the consumption of milk = 16 x fluid ounces

Thus, if y be the total milk in ounces that is used in x days,

The required function,

y = 16 x

B)  In 1 day,  consumption of milk = 16 ounces

⇒ 16\text{ ounces milk } = 1 \text{ day}

⇒ 8\times 16\text{ ounces milk } = 8\times 1 \text{ day}

⇒ 128\text{ ounces milk } = 8 \text{ day}

Since, 128 ounces = 1 gallon

⇒ 1\text{ gallon milk } = 8 \text{ day}

In 8 days, 1 gallon of milk will consumed.
