How many blue candles are there in a basket of 490 candles, if there are 3/4 as many orange candles as blue?
Mrrafil [7]

Answer:

210 orange candles

280 blue candles

Step-by-step explanation:

x = blue candles

y = orange candles

y = 0.75x

x + y = 490

x + 0.75x = 490

1.75x = 490

x = 280

280 + y = 490

y = 210

Help me find part A and B
Olegator [25]

Answer:

Step-by-step explanation:

From the given question,

a). m∠WAX = 60°

   If m(arc WX) = 100°

   Then by theorem,

   Angle formed between the chords in a circle, measures the half of the sum of intercepted arcs.

   m(∠WAX) = \frac{1}{2}(\text{arc WX + arcYZ})

   60° = \frac{1}{2}(100+\text{arcYZ})

   120 = 100 + arc YZ

   120 - 100 = arc YZ

   m(arc YZ) = 20°

b). m(arc WX + arc YZ) = 2(60°)

    m(arc WX + arc YZ) = 120°

What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Dmitrij [34]

Hey there!

The answer to your question is 4x^2+2x-2

Given:

x^2-3x+7 and 3x^2 +5x-9

First, we can start by adding like terms. The following are like terms:

x^2 and 3x^2

-3x and 5x

7 and -9

Now, we can add these pairs together, giving us:

4x^2

2x

-2

Now, add all this together, and we get our answer as:

4x^2 + 2x - 2

Have a terrificly amazing day!
