Answer:

-2.6y + 11.8

Step-by-step explanation:

Distribute -0.5 into 12y and -7 to get to this equation, 8.3 + 3.4y - 6y + 3.5.  Combine the two like terms together to get your answer which is -2.6y + 11.8.

Answer:

a. 180 votes were for blue

b. 60 votes were for green

Step-by-step explanation:

Fractions

It's known 5/8 of the votes of a school-wide election were for painting the school blue. Suppose there were x voters in school.

Since 5/8 were for blue, then

[tex]1-\frac{5}{8}=\frac{3}{8}[/tex]

Were for the rest of the colors. It's also known 5/9 of the remaining votes were for green, thus

[tex]1-\frac{5}{9}=\frac{4}{9}[/tex]

of the remaining votes were for red.

The votes for red are:

[tex]\frac{3}{8}\cdot\frac{4}{9}=\frac{1}{6}[/tex]

of the total voters.

We know these were 48 votes, thus

[tex]\displaystyle x=\frac{48}{\frac{1}{6}}[/tex]

[tex]x = 288[/tex]

There were 288 voters in school.

a. 5/8 were for blue, that is:

[tex]\frac{5}{8}*288=180[/tex]

180 votes were for blue

b. 288-180 = 108 votes were for others than blue, and 5/9 of them were for green:

[tex]\frac{5}{9}*108=60[/tex]

60 votes were for green and 108-60=48 votes were for red (as expected)

Answer:

y = 16, don't know if I'm 100% right but hope this helps.

Step-by-step explanation:

since they both equal Y they may be equal to each other

Then you would subtract 2x from both sides canceling it out on one side

2x + 8 = 5x - 4

-2x         -2x

This would make the equation 8 = 3x - 4

next you add the 4 from both sides

8  = 3x - 4

+4         +4

This will leave you with 12 = 3x

now you divide 3 from both sides and 12/3 = 4 makes X = 4

next you take (4) and plug it in to one of the equations

y = 2(4) + 8

y = 8 + 8

y = 16

Answer: 0.44

Step-by-step explanation:

First, let's count the total number of four-digit numbers.

Let's think it as four empty slots:

_ _ _ _

In each slot, we can put a single digit.

In the first slot, we have 9 options {1, 2, 3, 4, 5, 6, 7, 8, 9}

The zero is not an option here, because if there was a 0, this would be a 3 digit number, then the 0 can not be in the first slot.

For the second slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

for the third slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

for the fourth slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

The total number of combinations is equal to the product between the numbers of options for each slot, this means that we have:

Combinations = 9*10*10*10 = 9000

So there are 9000 different 4 digit numbers.

Now we want to find the probability of selecting a number at random that is equal or smaller than 5000.

Let's see the number of 4-digit numbers that are equal or smaller than 5000.

The smallest 4-digit number is 1000.

Then the number of numbers between 1000 and 5000 is:

5000 - 1000 = 4000

This means that there are 4000 4-digit numbers that are equal or smaller than 5000.

Now, the probability of selecting one of them at random is equal to the quotient between the number of 4-digit numbers that meet the condition (4000) and the total number of 4-digits (9000)

Then te probability is:

P = 4000/9000 = 4/9 = 0.44

To determine the length of silver colored ribbon that Pete will need to put around a circular logo, we need to calculate the circumference of the logo.

The circumference of a circle can be found using the formula C = πd, where C represents the circumference and d represents the diameter of the circle. However, we are not given the diameter of the logo, so we cannot determine the exact length of the ribbon needed.

Assuming Pete knows the diameter or radius of the logo, he can calculate the circumference using the formula mentioned above. Once the circumference is determined, Pete will know how many inches of silver colored ribbon he will need. It is important to ensure that Pete has a little extra ribbon in case of any measurement errors or mistakes during the ribbon placement.

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

-2.5(-3 + 4n + 8)

Step 2: Simplify

For simplifying an expression, there are some rules about the order in which the calculations should be performed. The order of rules is called BODMAS. Each letter in this word stands for an operation.

→ -2.5(-3 + 4n + 8) = 0

→ 7.5 + (-10n) + (-20) = 0

→ 7.5 - 10n - 20 = 0

→ -10n - 20 + 7.5 = 0

→ -10n - 12.5 = 0

→ -10n = 12.5

→ n = 12.5 ÷ -10

→ n = -1.25

Step-by-step explanation:

Polynomial long division is done using the same methods as for numerical long division. Each quotient term is multiplied by the divisor, and that product subtracted from the dividend to get the new dividend. You are done when the degree of the dividend is less than the degree of the divisor.

As with numbers, 0 is put where a placeholder is needed. Here, that is needed for the (missing) x^2 term in the dividend.

As with numbers, the remainder is expressed as a fraction using the divisor as the denominator.

The full quotient is 4x^2 +2x +11/4 +37/(8x-4).

Answer:

57.926%

Step-by-step explanation:

Calculation for the probability that it is less than

16.4 inches long

Using this formula

z = (X - μ) / σ

Where,

X represent Date=16.4

μ represent Mean=16.2

σ represent Standard deviation=0.9 inches

Let plug in the formula

z = (16.4 - 16.2) /0.9 inches

z=0.2/0.9 inches

z = 0.2

Using Z-score table to find the area of 0.2

z=0.57926*100

z=57.926%

Therefore the probability that it is less than

16.4 inches long is 57.926%
