Answer:

x + y = 15

y = 3x + 1.5

x + (3x + 1.5) = 15

Step-by-step explanation:

Let :

Soft ball practice = x

Soccer practice = y

y = 3x + 1.5

Total practice time :

x + y = 15 - - - (1)

x + 3x + 1.5 = 15

4x + 1.5 = 15

Greta is trying to determine the portion of green candies in various bags of green and yellow candies. Using the information bel
IrinaK [193]

Answer: a) \dfrac{1}{3} b) \dfrac{71}{100} c) \dfrac{5}{9}

Step-by-step explanation:

Since we have given that

There are green and yellow candies in each bag.

Bag A: Two thirds of the candies are yellow. What portion of the candies is green?

Part of yellow candies in bag A = \dfrac{2}{3}

Part of green candies in bag A would be

1-\dfrac{2}{3}\\\\=\dfrac{3-2}{3}\\\\=\dfrac{1}{3}

Bag B: 29 % of the candies are yellow. What portion of the candies is green?

Percentage of candies are yellow = 29%

Portion of candies are green is given by

1-\dfrac{29}{100}\\\\=1-0.29\\\\=0.71\\\\=\dfrac{71}{100}

Bag C: 4 out of every 9 candies are yellow. What portion of the candies is green?

Portion of yellow candies = \dfrac{4}{9}

Portion of green candies would be

1-\dfrac{4}{9}\\\\=\dfrac{9-4}{9}\\\\=\dfrac{5}{9}

Hence, a) \dfrac{1}{3} b) \dfrac{71}{100} c) \dfrac{5}{9}

A salesman is carrying a big bag for selling a machine. In addition to the machine that the salesman wants to sell, there is som
stira [4]

The total weight of the bag that the salesman is carrying for selling a machine including some personal stuff is 13.9 Kg.

<h3>What is a fraction?</h3>

A fraction is a rational number that consists of a numerator and a denominator, used to represent a part of the whole thing.

<h3>Calculation:</h3>

It is given that,

A salesman is carrying a big bag for selling a machine.

Consider the weight of the machine = w

So,

The weight of his machine is three kilograms and half a machine. I.e.,

w = 3kg +w/2

⇒ w/2 = 3kg

∴ w = 6kg

Thus, the weight of the machine is 6 Kg.

So, the weight of the repair tool for the machine = a half kilogram and one-fourth of the machine

⇒ 1/2Kg + 1/4w

⇒ 1/2 + 6/4

⇒ 2 Kg

The personal stuff weighs - four kilograms minus a fourth of the weight of the machine.

⇒ 4Kg - w/4

⇒ 4 - 6/4

⇒ 2.5 Kg

He has some supplies that weigh two-fifth of the machine and personal stuff combined.

⇒ 2/5(w + 2.5)

⇒ 2/5 × 8.5

⇒ 3.4 Kg

Thus, the total weight of the bag = 6 Kg + 2 Kg + 2.5 Kg + 3.4Kg =  13.9Kg.

Therefore, the total weight of the salesman's bag is 13.9 Kg.
