Step-by-step explanation:

Note: You seem to have missed entering the complete question. I am assuming you want to get the simplified version of the stated expression. So, I will solve it accordingly.

Answer:

The simplification of the expression is:

[tex]3\left(4h+2k\right)\cdot \:3=\:36h+18k[/tex]

Step-by-step explanation:

Given the expression

[tex]3\left(4h+2k\right)3[/tex]

simplifying the expression

[tex]3\left(4h+2k\right)3[/tex]

[tex]=3\left(4h+2k\right)\cdot \:3[/tex]

[tex]=3\cdot \:3\left(4h+2k\right)[/tex]

[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac[/tex]

[tex]=3\cdot \:3\cdot \:4h+3\cdot \:3\cdot \:2k[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:3\cdot \:3\cdot \:4=36[/tex]

[tex]=36h+3\cdot \:3\cdot \:2k[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:3\cdot \:3\cdot \:2=18[/tex]

[tex]=36h+18k[/tex]

Therefore, the simplification of the expression is:

[tex]3\left(4h+2k\right)\cdot \:3=\:36h+18k[/tex]

Answer:

1 3/8 miles per hour

Step-by-step explanation:

The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate their unit rate in miles per hour?

3/5mile = 3/8 hour

Their unit rate in miles per hour or speed

= Distance/Time

Hence,

3/5mile ÷ 3/8 hour

= 3/5 × 8/3

= 8/5 miles per hour

= 1 3/8 miles per hour

Therefore, their unit rate in miles per hour is 1 3/8 miles per hour.

Answer:

1 3/8 miles per hour

Step-by-step explanation:

The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate their unit rate in miles per hour?

3/5mile = 3/8 hour

Their unit rate in miles per hour or speed

= Distance/Time

Hence,

3/5mile ÷ 3/8 hour

= 3/5 × 8/3

= 8/5 miles per hour

= 1 3/8 miles per hour

Therefore, their unit rate in miles per hour is 1 3/8 miles per hour.

Answer:

[tex]y=\frac{1}{2}x[/tex]

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (2, 1), (-4, -2)

(2, 1) = (x1, y1)

(-4, -2) = (x2, y2)

To write the equation in slope-intercept form we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the formula used to find slope:

[tex]\frac{-2-1}{-4-2}[/tex]

Simplify:

-2 - 1 = -3

-4 - 2 = -6

[tex]\frac{-3}{-6} =\frac{1}{2}[/tex]

The slope is [tex]\frac{1}{2}[/tex]. We can input the slope and one of the given points (in this example I'll use point (2, 1)) into the equation to find b:

[tex]1= \frac{1}{2}(2)+b[/tex]

1 = 1 + b

0 = b

The y-intercept is 0. Now that we know the slope and the y-intercept, we can write the equation:

[tex]y = \frac{1}{2}x+0[/tex]

[tex]y=\frac{1}{2}x[/tex]

Answer:

10 gallons

Step-by-step explanation:

If 60 gallons of water drains in 6 minutes, that means that to find the amount drained per minute, you would have to divide the number of gallons per minute. So 60 gallons÷6 minutes is 10 gallons per minute.

Answer:

The average price per square yard is $8.00

Step-by-step explanation:

From the question

849 yd² = $6,796

1 yd² = x

Cross Multiply

849 yd² × x = 1 yd² × $6,796

x = 1 yd² × $6,796/849yd²

x = $8.0047114252

Approximately = $8.00

Therefore, the average price per square yard is $8.00

Answer:

13,23

Step-by-step explanation:

The required number of t-shirts and hats is given as, 45 and 15 respectively

Given that,
The senior class at Northwest High School needed to raise money for the yearbook. A local sporting goods store donated hats and T-shirts. The number of T-shirts was three times the number of hats. The seniors charged $5 for each hat and $8 for each T-shirt. If the seniors sold everything and raised $435,

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
let the number of hats be x and y be the number of T-shirts,
According to the question,
y = 3x  - - - - (1
And,
5x + 8y = 435
From equation 1
5x + 8{3x} = 435
5x + 24x = 435
29x = 435
x = 15
Now put x in equation -1

y = 3 × 15
y = 45

Thus, the required number of t-shirts and hats is given as, 45 and 15 respectively

Answer:

1: Domain: 2, 4, 3, 6, 2

2: Range: -3, 6, -1, 6, 3

3: Not a function

Explanation:

Domain is x-values aka input value. Range is y-value aka output value. The input value (x) is the first number in the ordered pair and the output value (y) is the second number. For example, say the pair is (4,6) The input value is 4 and output value is 6. We could also say 4 is the Domain and 6 is the Range. In conclusion, x is Domain and range is y.

In order for a set of pairs to be a function, the x values can't be repeated. For example, say the the x values are 3, 6, 7, 4, and 3. Then, this is not a function because there are two 3's that are x values. This only applies for x value (input value) and not y value. There can be multiple of the same y-values aka output value.

Answer:

y = -10

Step-by-step explanation:

(-7x+3y) - (-7x +10y) =-65 -(-135)

-7x + 3y + 7x -10y = 70

-7y = 70

y = -10

The equation that results from subtracting - 7x + 3y = - 65 and

- 7x + 10y = - 135 is 7y = - 70.

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.

Subtracting the first equation from the second we get,

   - 7x + 10y = - 135

(-) - 7x + 3y =    - 65

_________________

Negative sign gets distributed

   - 7x + 10y = - 135

  + 7x - 3y =   + 65

_________________

            7y =   - 70

              y =   - 70/7

              y =  - 10.

So, the value of x is -7x +10×(-10) = - 135.

- 7x - 100 = - 135.

- 7x = - 135 + 100.

- 7x = - 35.

x = 7.
