factorise 7a + 14b + ax + 2bx
​

Answer:

4.5 hours

Step-by-step explanation:

So, let's write a function p(x) which represents the total cost.

Let's let x represent the amount of hours.

The cost of a piece is a constant 10.

And there is a $8 fee per hour. In other words:

[tex]p(x)=8x+10[/tex]

We spent a total of $46.

So, substitute in 46 for p(x) and solve for x:

[tex]46=8x+10[/tex]

Subtract 10 from both sides:

[tex]36=8x[/tex]

Divide both sides by 8:

[tex]x=36/8[/tex]

Reduce:

[tex]x=4.5[/tex]

So, we spent about 4.5 hours.

Answer:

x- intercept is at [tex]( \frac{3}{7} ,0)[/tex].

Answer:

$98.67

Step-by-step explanation:

109(.15)= $16.35 You multiply by .15 to find out what 15% of the total (109) is going to be discounted.

109-16.35= 92.65 You subtract the discount from the total to come up with the new total.

92.65(1.065)= 98.67225 =98.67 You take the discounted total, 92.65, and multiply it by 1.065 which represents how you will will be paying for sales tax.

Answer:

[See Below]

Step-by-step explanation:

❶ It is irrational because to make it repeating it must be EXACT. In this case it is adding a 0 after every 1. So it'd be irrational since it doesn't have an end.

❷ Irrational because no one knows the end of pi. It doesn't have an ending so therefore irrational.

Answer:

9/50

Step-by-step explanation:

First, convert the decimal into a fraction. In this case, convert .18 to 18/100. Find a common factor between the numerator and denominator, which in this case, would be 2. Divide both the numerator and denominator by 2 to get 9/50. 9/50 can't be simplified further, so this is your answer.

Answer:

[tex]\frac{9}{50}[/tex]

Step-by-step explanation:

0.18 is [tex]\frac{18}{100}[/tex].

Let's simplify the fraction:

[tex]\frac{18}{100}= \frac{18/2}{100/2}=\boxed{\frac{9}{50}}[/tex]

Hope this helps.

Answer: 2.6

Step-by-step explanation:

1. We know that A to C is 14

2. B to C is 11.4 so we're going to find the remainder to equal 14.

3. 14 minus11.4 which equals 2.6

4. AB is 2.6

Answer:

The expression simplified is a^2

Step-by-step explanation:

Here, we are interested in writing the product as a single value.

We have; a^5 • a^-3

This is same as a^5 * a^-3

We proceed here using the first law of indices;

It would result to a^5 * a^-3 = a^(5-3) = a^2

Answer:

C. 78 cm

Step-by-step explanation:

The mean of any given data set is calculated as sum of all data set divided by the number of data set given.

The data set for the height of Bella's corn given, is 81, 88, 69, 65, 87

Mean height of Bella's corn = [tex] \frac{81 + 88 + 69 + 65 + 87}{5} [/tex]

[tex] mean = \frac{390}{5} [/tex]

[tex] mean = 78 cm [/tex]

You are required to calculate the mean of the height, in other words, the average of the height

The mean of the height is 78

Given height

81, 88, 69, 65, 87

Mean = Total height / number of height

= (81 + 88 + 69 + 65 + 87) / 5

= 390 / 5

= 78

Mean of the height = 78

x = -33.5

Answer:

x= -33 1/2 (-33.5)

Step-by-step explanation:

2x=-67

x=-67/2

x= -33 1/2 (-33.5)

Answer:

x-y/2z=3

2z(x-y)/2z = 3 × 2z

x-y = 6z

x-y/6 = 6z/6

z = x-y/6

x-y/2z = 3

2z(x-y)/2z = 3 × 2z

x - y = 6z

x-y+y = 6z + y

x = 6z + y

x-y/2z=3

2z(x-y)/2z = 3 × 2z

x-y = 6z

-x + x - y = 6z - x

-y = 6z - x

-y/-1 = 6z - x / -1

y = -6z + x

The expression is written as;

⇒ x = 6z + y

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ (x - y) / 2z = 3

Now, Simplify the expression for x as;

⇒ x - y = 3 × 2z

⇒ x - y = 6z

⇒ x = 6z + y
