What is the sum -4x + 2 and 7x-10?
HURRRYY PLZZZ

Answer:

1) x = 42 ; y = 42

2) x = 72 ; y = 48 ; z = 60

Step-by-step explanation:

1)

x + 42 + 96 = 180

x + 138 = 180

x = 42

y + 42 + 96 = 180

y + 138 = 180

y = 42

2)

x + 108 = 180

x = 72

y + 132 = 180

y = 48

z + x + y = 180

z + 72 + 48 = 180

z + 120 = 180

z = 60

Answer:

it is y=-3/2x+6 and then you subtract it by 2 and then add 7 and then u get 49

Step-by-step explanation:

WARNING - I wasn't told whether if it was annual or monthly contributions so this might not be correct.

$1449.00

I = 2300 × 0.07 × 9 = 1449

I = $ 1,449.00

b is your correct answer hope help you

First, convert. Least common multiple of 3 and 7 is 21.

2x7=14 3x7=21.

4x3=12 7x3=21.

The new fractions are 14/21 and 12/21.

Which is bigger?

Answer:

-21 tickets per hour

Step-by-step explanation:

I think it's right

Answer:

Therefore, the correct answer is option C. 21 tickets per hour.

Step-by-step explanation:

Given: the opening day ticket sales for the park is given by the function[tex]T(h)=\frac{386+110h}{h}[/tex] where [tex]T(h)[/tex] represents the number of tickets sold [tex]h[/tex] hours after opening at 7:00 a.m.

To find: the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m.

For 10 a.m., [tex]h=3[/tex]

So the number of tickets sold upto 10 a.m. are,

[tex]T(3)=\frac{386+110 (3)}{3}[/tex]

[tex]T(3)=238.67[/tex]

Similarly, for 1 p.m., [tex]h=6[/tex] hours

So, the number of tickets sold in 6 hours are,

[tex]T(6)=\frac{386+110(6)}{6}[/tex]

[tex]T(6)=174.33[/tex]

Now, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is,

[tex]\frac{T(6)-T(3)}{6-3}[/tex]

[tex]=\frac{174.33-238.67}{3}[/tex]

[tex]=-21.445[/tex]

which is approximately [tex]-21[/tex] tickets per hour.

Hence, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is -21 tickets per hour.

The correct answer is option C.

The answer is 4a

Step-by-step explanation:

1) Simplify 4a² + 12a² to 16a².

[tex] \sqrt{ {16a}^{2} } [/tex]

2) Use this rule:

[tex] \sqrt{ab} = \sqrt{a} \sqrt{b} [/tex]

[tex] \sqrt{16} \sqrt{ {a}^{2} } [/tex]

3) Since 4 × 4 is 16, the square root of 16 is 4.

[tex]4 \sqrt{ {a}^{2} } [/tex]

4) Simplify.

Answer:

the percentage increase for bread and cake is 66.67% and 20% respectively  

Step-by-step explanation:

The computation of the percentage increase for each bakery item is shown below:

For bread

= (25  - 15) ÷ 15

= 66.67%

For cakes

= (12 - 10) ÷ (10)

= 20%

Hence, the percentage increase for bread and cake is 66.67% and 20% respectively

Possible Outcomes:

It is a list of all the resulting possibilities from an event.

(Here),

when he flips the coin, there are 2 outcomes = {front, back}

When he rolls a die, there are 6 outcomes = {1, 2, 3, 4, 5, 6)

For every outcomes of coin there are 6 outcomes of a die.

So, Possible outcomes = 2 * 6 = 12.

Step-by-step explanation:

Answer:

13 boxes

Step-by-step explanation:

Given

See attachment for closet

Required

Determine the number of boxes needed to fill the closet

First, we calculate the volume of the two section.

[tex]Volume = Width * Length * Height[/tex]

From the attachment

The first section is:

[tex]Width = 5ft\\ Length = 4ft\\ Height = 8ft[/tex]

[tex]V_1 = 5ft * 4ft * 8ft[/tex]

[tex]V_1 = 160ft^3[/tex]

The second section:

[tex]Width = 3ft\\ Length = 2ft\\ Height = 8ft[/tex]

The width is the last label at the top

The length is the difference between the length of the first section (4ft) from the total length of the closet (6ft) i.e. 6ft - 4ft

The volume is:

[tex]V_2 = 3ft * 2ft * 8ft[/tex]

[tex]V_2 = 48ft^3[/tex]

Total volume (V) is:

[tex]V = V_1 + V_2[/tex]

[tex]V = 160ft^3 + 48ft^3[/tex]

[tex]V = 208ft^3[/tex]

The number of box (n) needed is then calculated by dividing the calculated volume of the closet by the volume of each box

[tex]n = \frac{208ft^3}{16ft^3}[/tex]

[tex]n = 13[/tex]

Answer:

Volume of a rectangular prism can be found with the equation

v = length × width × height

They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...

18 inches = 1.5 ft

v = l×w×h

v = 3×2×1.5

v = 9 ft^3

Volume=length*width*height, so first you would have to change the units of the inches to feet, which would be 90/12=7.5, so now you can fit that into the equation, 2*3*7.5=45 ft cubed!
