Answers

Answer:

x = 4, y = -2

Step-by-step explanation:

Answer:

x = 4

y = -2

Step-by-step explanation:

[tex]3x + 5y = 2[/tex]

[tex]y = 2x - 10[/tex]

[tex]3x + 5(2x - 10) = 2[/tex]

[tex]3x + 10x - 50 = 2[/tex]

[tex]13x = 52[/tex]

[tex]x = 4[/tex]

Now,

In a group of 38 pupils, 14 play the flute only.
8 play the piano only.
11 play both instruments.
A student is chosen at random.
What is the probability the student plays neither instrument?

pLZZZZZ need help, will give brainlist if solved

Answers

Hey there!

The answer to your question is 5/38

We can find this answer by taking the total group and subtracting all the data to see how many are left who don't play either:

38 - 14 - 8 - 11

This means that 5 out of every 38 pupils do not play either instrument, so the probability would be 5/38.

Hope this helps! Have a great day and good luck on your assignment!

Lily is selling ice cream cones and ice cream sandwiches. She sells 3 ice cream cones and 4 ice cream sandwiches for $14.25. She sells 5 ice cream cones and 2 ice cream sandwiches for $13.25. How much is an ice cream cone? How much is an ice cream sandwich?

Answers

Answer:

cost of ice cream cones = $1.75

cost of ice cream sandwiches = $2.25

Step-by-step explanation:

Let

x = cost of ice cream cones

y = cost of ice cream sandwiches

3x + 4y = 14.25 (1)

5x + 2y = 13.25 (2)

Multiply (2) by 2

10x + 4y = 26.50 (3)

3x + 4y = 14.25 (1)

Subtract (1) from (3)

10x - 3x = 26.50 - 14.25

7x = 12.25

x = 12.25/7

x = $1.75

Substitute x = 1.75 into (1)

3x + 4y = 14.25

3(1.75) + 4y = 14.25

5.25 + 4y = 14.25

4y = 14.25 - 5.25

4y = 9

y = 9/4

y = $2.25

Answer:

cost of ice cream cones = $1.75

cost of ice cream sandwiches = $2.25

Step-by-step explanation:

Let

x = cost of ice cream cones

y = cost of ice cream sandwiches

3x + 4y = 14.25 (1)

5x + 2y = 13.25 (2)

Multiply (2) by 2

10x + 4y = 26.50 (3)

3x + 4y = 14.25 (1)

Subtract (1) from (3)

10x - 3x = 26.50 - 14.25

7x = 12.25

x = 12.25/7

x = $1.75

Substitute x = 1.75 into (1)

3x + 4y = 14.25

3(1.75) + 4y = 14.25

5.25 + 4y = 14.25

4y = 14.25 - 5.25

4y = 9

y = 9/4

y = $2.25

An information technology company produces 45% of its computer chips at a plant in St. Louis and the remainder of its chips at a plant in Chicago. It is known that 0.85% of the chips produced in St. Louis are defective, while 1.05% of the chips produced at the plan in Chicago are defective. What is the probability that a randomly chosen computer chip produced by this company is defective and was produced in St. Louis?

Answers

Answer:

the probability of the computer chip produced and defective is 0.003825

Step-by-step explanation:

The computation of the probability of the computer chip produced and defective is shown below

= Produced percentage × defective percentage

= 45% × 0.85%

= 0.003825

Hence, the probability of the computer chip produced and defective is 0.003825

A pair of basketball shoes's normal price is $120. Jordan bought it at a discount of 10%. He had to pay 8% tax on the discounted price. If jordan put 15% of the final cost (including tax) as a down payment, how much money did he have to pay for the down payment?

Answers

Answer:

$17.50

Step-by-step explanation:

If the shoes are discounted at 10%, the price would be 90% of the original price

Discounted price = 0.9 x 120 = 108

Tax increases the price of the good. so, the discounted price would increase by 8%

1.08 x 108 =116.64

If Jordan pays 15% as a down payment, he would pay :

0.15 x 116.64 = 17.496

Answer:

Row III and Row V

Step-by-step explanation:

Whole numbers are all positive numbers including 0. However, these numbers cannot have fractions or decimals. Integers include numbers that are negative and positive, however they cannot have fractions or decimals either. 0 counts as an integer, too. Rational numbers are numbers that can be written as a fraction. Decimals can be rational, too - they just have to either terminate (end at some point) or repeat. Knowing these rules...

-98 would qualify as an integer and a rational number - but not a whole number because it's negative. Row I is correct. 0 would qualify as an integer, whole number, and rational number. Row I is correct. -0.7878... would not qualify as an integer or whole number - it is a decimal - but it would qualify as a rational number since it repeats. Therefore, Row III is wrong. [tex]2\frac{15}{17}[/tex] would not qualify as an integer or whole number - it is a fraction - but it would qualify as a rational number. It can be written as a fraction. Row IV is correct. 10.5 would not qualify as an integer or whole number - it is a decimal number - but it could be rational since it can be written as [tex]10 \frac{1}{2}[/tex]. Row V is wrong.

Mike wants to make meatloaf. His recipe
uses a total of 4 pounds of meat.
If he uses a 3 to 1 ratio of beef to pork, how much pork will he use?

Answers

Answer:

[tex]1\:\mathrm{pound}[/tex]

Step-by-step explanation:

We can write the following equation using the information given:

[tex]3x+1x=4[/tex], where [tex]x[/tex] is some constant.

Solving, we get:

[tex]4x=4,\\x=1[/tex].

Therefore, we plug in [tex]x=1[/tex] to find the amount of meat he uses for each type:

Beef: [tex]3x=3(1)=3\:\mathrm{pounds}[/tex]

Pork: [tex]1x=1(1)=\fbox{$1\:\mathrm{pound}$}[/tex].

The nature park has a pride of 6 lions and 4 cubs. The adults eat 9 pounds of meat each day and the cubs eat 3 pounds. Simplify 6 × 9 + 4 × 3 to find the amount of meat consumed each day by the lions.

Answers

Answer:

Step-by-step explanation:

6 × 9 + 4 × 3

We use PEMDAS to determine the order in which the mathematical operations would be carried out.

PEMDAS is an acronym for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

Multiplication comes first so;

6 × 9 + 4 × 3

54 + 12

We can then add both numbers.
