Simplify the expression below:
20 – 10y – 7y + 9

Answer:

Around $1.47

Step-by-step explanation:

To find the unit rate you need to have a denominator of one. (5.89/4 = x/1)

All you have to do is divide 5.89 by 4 and you get 1.4725 and if you round that to the nearest 100th place you get 1.47.

So 1 once cost $1.47

I hope this helps, and have a great day!

Answer:

Step-by-step explanation:

Answer:

y + 1 = 8 (x + 7)

Step-by-step explanation:

point slope form is

y - y1 = m (x - x1)

So replace the y1 with the y point, and the x1 with the x point

y - (-1) = m (x - (-7) )

then replace the m with the slope

y - (-1) = 8 (x - (-7) )

now solve

y + 1 = 8 (x + 7)

Answer:

they are parallel

Step-by-step explanation;

You would have to get the Y by itself in the bottom one so go

2x-3y=-3

-2x        -2x

-3y=2x-3

_________

-3        -3

_________

y= -2/3x+ 1

and they are the same equaion

so they end up parallel

Answer:

x= 6

y= -2

Step-by-step explanation:

y = x-8........equation 1

y= 2x-14.......equation 2

Substitute x-8 for y in equation 2

x-8= 2x-14

x-2x= -14+8

-x= -6

x= 6

Substitute 6 for x in equation 1

y= x-8

y= 6-8

y= -2

Hence x = 6 and y is -2

Answer:

x=1.7320508075688772 or x=−1.7320508075688772

Step-by-step explanation:

(x2−3)(x2+12)=0

x4+9x2−36=0

(x2−3)(x2+12)=0

x2−3=0 or x2+12=0

x=1.7320508075688772 or x=−1.7320508075688772

Answer:4:1

Step-by-step explanation: you have to find the unit rate ( how much for 1) so you set 3 to equal 1 and to do that you divide by three so you do that to the 12 also

A section, or cross-section, is a view of a 3-dimensional object from the position of a plane through the object. A section is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. It is often used in technical drawing and is traditionally crosshatched.

Cross sections of three-dimensional objects are two-dimensional shapes of various sizes. They may be parallel to a side or base of the object or at an angle to these surfaces. A cross section may resemble the shape of the object’s side or base, or it may have a completely different shape.

Answer:

108 x 25²  divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]

Step-by-step explanation:

Given;

108 x 25²  divided by 2⁶ x 5²

The expression is simplified as follows;

[tex]\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}[/tex]

Therefore, 108 x 25²  divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]

Answer:

i have know

Step-by-step explanation:

From the Moore's Law, the predicted number of transistors per IC in 1992 would be approximately 4,096,000.

Given data:

Based on this exponential growth pattern, use the estimate of 4,000 transistors per IC in 1972 to predict the number of transistors per IC in 1992.

To predict the number of transistors per IC in 1992, determine how many doublings occurred during the 20-year period from 1972 to 1992.

Since each doubling represents a multiplication by 2, calculate the number of doublings as follows:

Number of doublings = (1992 - 1972) / 2

Number of doublings = 20 / 2

Number of doublings = 10

Now, use this number of doublings to predict the number of transistors per IC in 1992:

Predicted number of transistors per IC in 1992 = 4,000 * (2^10)

Predicted number of transistors per IC in 1992 = 4,000 * 1,024

Predicted number of transistors per IC in 1992 ≈ 4,096,000

Hence, based on Moore's Law and the estimate of 4,000 transistors per IC in 1972, the predicted number of transistors per IC in 1992 would be approximately 4,096,000.

Answer:

1) $68.40

2)456 tickets

Step-by-step explanation:

1)

They need to raise $8,250.

They have already raised $3,120.

The amount they have still to raise is $8,250-$3,120=$5,130.

There are 75 band members, so the amount yet to raise per member is $5,130/75=$68.40.

2)

The businesses give $0.50 for every $1 in ticket sales, ie. they pay an extra 50% of the total.

Let number of tickets sold=x

Let money made from ticket sales = 7.5x

The total amount of money made is therefore 1.5(7.5x)=11.25x

The minimum amount of tickets to hit $5,130:

$5,130=11.25x

x=456

Answer:

Streamers cost 2.50 and balloons cost 1.25.

Step-by-step explanation:

Pls mark brainliest.

Answer:

Balloon : $1.25

Streamer : $ 2.50

Step-by-step explanation:

Form simultaneous equations.

Let streamer be represented by ------------s

Let balloons be represented by ------------b

So the equations will be;

3s + 2b = 10 ----------------i

2s + 1b = 6.25---------------ii

Make the terms with s equal by multiplication

[3s + 2b = 10 ]2

[2s + 1b = 6.25]3

Perform subtraction

6s + 4b = 20

6s + 3b = 18.75

b = 1.25 ---------iii

Use  iii  in ii  as;

2s + 1b = 6.25

2s + 1.25 = 6.25

2s = 6.25 - 1.25

2s = 5.00

s= 5.00 / 2

s= 2.5

Hence ; a balloon is  $1.25   and a streamer is $2.5
