-9x + 2y = 5
9x − 4y = -19

Answers

hi hruStep-by-step explanation:

-9 + 2y = 5
9x - 4y = -19

Add these equations to eliminate x:
-2y = -14

Then solve -2y = -14 for y:
-2y = -14
-2 -2
(Divide both sides by -2)

y=7

Substitute 7 for y in -9x + 2y = 5:
-9x + (2)(7) = 5
-9x + 14 = 5
-14 -14
(Subtract 14 from both sides)
-9x = -9
-9 -9
(Divide both sides by -9)
x = 1

At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors: white, red, green, and blue. There are 10 boxes of each color. All the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color? (1 point)

Select one:
a. (10/40) * (9/39)
b. (10/40) * (10/39)
c. (10/40) + (9/39)
d. (10/40) + (10/39)

Answers

Answer:

a. (10/40) * (9/39)

Step-by-step explanation:

Since, the total number of white box = 10,

Red box = 10,

Green box = 10,

And, Blue box = 10,

Thus, the total number of boxes = 10 + 10 + 10 + 10 = 40

The probability of receiving white box by first winner =  White box / Total box = 10/40

Since, the replacing is not allowed ( Because, here boxes are allotted )

Thus, the remaining white box = 10 - 1 = 9,

And, the remaining total boxes = 40 - 1 = 39,

Thus, the probability of receiving white box by second winner = Remaining white box / Remaining total box = 9/39

Hence, the probability of the first winner receiving a white box and the second winner also receiving a box of the same color = 10/40 * 9/39

Which is required expression.

Use the angle relationship to find the value of x.

Answers

Answer:

Hello! answer: x = 11

Step-by-step explanation:

These are vertical angles in simple terms meaning they are across from each other and if you folded them over each other they would match up and they will equal the same measure so 13 × 11 = 143 143 - 10 = 133 therefore x = 11 Hope that helps!

X = 11
Both of those angles are equal to each other, so 133= 13x-10, add 10 from both sides to cancel out the “-10”. You get 143=13x and then divide both sides by 13 and you get x= 11

Chill dude.                          

Stop with the all caps.    

25 is the answer.

G = green sweets

Ratio of blue to green = 3:5

Ratios are essentially fractions, and can be converted into fraction form

Therefore, number of blue sweets is 3/5 of green sweets, which can also be represented as 3/5g

Number of green sweets to red sweets is 6:1

We can also flip this ratio around and the ratio would still have the same value.

Number of red sweets to green sweets = 1:6

In fraction form, the number of red sweets is 1/6 of green sweets, which is also 1/6g.

Since there are less than 270 sweets in the box, we can use this expression to represent the sweets in the box:

G + 3/5g + 1/6g < 270

Find a common denominator for the fractions.

5 * 6 = 30, thus a common denominator would be 30.

Since G is a variable with no coefficient, 1 would be implied because no coefficient is present.

So when multiplying G to get a common denominator, the numerator would be 30. 30/30 = 1

G * 30 = 1 * 30

G = 30/30g

Multiply the rest of the numerators and you’ll get:

30/30g + 18/30g + 5/30g < 270

Add.

1 + 18/30g + 5/30g = 1 23/30g

Convert this into an improper fraction.

53/30g < 270

Now divide both sides by 53/30.

(53/30g) ÷ (53/30) < 270 ÷ (53/30)

= g < 270 ÷ (53/30)

Dividing fractions is complex, so you can simply switch the numerator and denominator and multiply:

G < 270 x (30/53)

= g < 8,100/53

Since the number of red sweets to green sweets is 1/6g the number of green sweets, the number of red sweets is 1/6 of 8,100/53.

R = red sweets

R < 8,100/53 x 1/6

8,100 x 1 = 8,100

53 x 6 = 318

R < 8,100/318

318 goes into 8,100 25 times, regardless of any remainder.

Therefore, the greatest possible number of red sweets in the box is 25 red sweets.

Answers

Step-by-step explanation:

All numbers belong to the set of numbers known as the real number system. The real number system consists of

every number you have ever dealt with since you were old enough to count. The numbers in the real number system

are divided into two main groups. One group is called the rational numbers and the other is called the irrational

numbers. The set of irrational numbers consists of all numbers that are not rational. This set of irrational numbers

includes those numbers that cannot be written as the ratio of two integers, non-remediate numbers.

and decimals that do not have a repeating pattern of digits. For example, pi(π),

√

2,−2.345876921... are irrational

numbers.

The set of rational numbers includes natural numbers, whole numbers, integers, numbers that can be expressed as

the ratio of two integers, a decimal number that terminates, and decimal numbers that have a repeating pattern of digits.

The natural numbers are the set of positive integers. For example, 1, 2, 3. . . are all natural numbers. The whole

numbers are the natural numbers and zero. For example, 0, 1, 2, 3. . . are all whole numbers. The integers are

the whole numbers and their opposites. For example, -2, -1, 0, 1, 2. . . are all integers. A rational number is any

number that can be expressed in the form of a

b where b 6= 0. When a rational number is expressed as a decimal, it

decimal will terminate (end) or For example, 1

2

,

√

81,−7.456 545 654 are

all rational numbers.

When you classify numbers remember that they can often belong to more than one set of numbers. If you think of

the number 3, you can call it a natural number, a whole number, an integer and a rational number.

If is the small angle is a 3-4-5 right triangle, then sin = ? The picture shows a pika, a small mammal found in grassland ecosystems. The vast grasslands of the Tibetan plateau are home to the plateau pika. The numerous pikas are prey for many predators of the grasslands, which serve as a major watershed for much of the area. The watershed drains large quantities of groundwater during the rainy season or the monsoon season. Pikas have extensive burrows that help drain groundwater rapidly and are used as nesting sites by many bird species. However, many people advocate the eradication of the plateau pikas because they compete with livestock for grass. 1. The ecosystem will become unstable because predators will have fewer prey, the birds will have fewer nesting sites, and the area downriver will become vulnerable to flooding without the burrows to aerate the soil and provide drainage for monsoon rains. 2. The ecosystem will become more stable because the pika will be replaced by other species of small mammals that can fill the niche, bird species will adapt to nesting aboveground, and the soils will become compacted without the burrows. 3. The ecosystem will become unstable because the predators will migrate to nearby ecosystems, the birds will nest in nearby trees, and the soils will be aerated by other small mammals. 4. The ecosystem will become more stable because the pika will no longer be there to eat the grasses, the birds will migrate to other ecosystems during nesting season, and the soils will be able to absorb more of the monsoon rains without the pika burrows.
