I need help with math ​

Answer:

x = 2

Step-by-step explanation:

5x – 4 – 9x = 4(x - 5)

-4x -4 = 4x -20

-4x -4x = -20+4

-8x = -16

x = -16/-8

x = 2

Answer:

Step-by-step explanation:

Area of the rectangle = length * width

                                   = 10 * 5

                                   = 50 m²

Area of the smaller rectangle that is white color = 7 * 2

                                                                               = 14 m²

Triangle:

base = b = 5 m

Height = h = 16 - 10 = 6 m

Area of triangle = [tex]\frac{1}{2}*b*h\\[/tex]

                          [tex]= \frac{1}{2}*5*6\\\\= 5*3\\\\= 15 m^{2}[/tex]

Area of shaded area = area of bigger rectangle - area of smaller rectangle + area of triangle

 = 50 - 14  + 15

= 21 m²

Answer:

27

Step-by-step explanation:

6x3=18, which means the bottom half of the shape is 18. The top half is a triangle, and triangles are half a square or rectangle. So again, 6x3=18. 18/2=9. So 18+9=27. So the ANSWER IS 27

Step-by-step explanation:

45  x 30% = $13.5 is saved

Answer: You will save $13.5

Step-by-step explanation: We all know that $45.00= 100% of the money do 45.00 x 30= 1350 and divide 100= $13.5

Answer:

First blank is >=

Second blank is <=

Step-by-step explanation:

At least means the sign is greater than or equal to

No more than means the sign is less than or equal to

Answer:

B and C

Step-by-step explanation:

IT is found that B. 56 mph and C. 48 mph car speed measurements represent the same level of accuracy compared to the speed limit sign.

Speed can be calculated as the ratio of distance traveled to the time taken

We can see that As the speed limit on the highway is 60 miles per hour and the speeds mentioned above are below the speed limit.

The legal top speed at which a vehicle may travel on a specific section of road is determined by speed limits for road traffic, since they are utilized in the most of countries.

On a traffic sign, it is known that the maximum allowed speed is typically displayed and expressed in kilometers per hour (km/h) or miles per hour (mph).

Hello, my name is Zalgo, and I would be honored to help you out on this Fantastic Friday. The answer to your question would be that X=81. (if you want/need the , it will be down below).

I hope this all helps you out and I hope you have a nice day.

In order to get the answer, first calculate the product for [tex]3*(3^4)=3x[/tex] which will get you [tex]3^5=3x[/tex].

Then you'll want to divide both sides of the equation by 3, taking you from [tex]3^5=3x[/tex] to [tex]3^4=x[/tex].

After that, you need to evaluate the power, so now you have went from [tex]3^4=x[/tex] to 81=x.

And the final step would be to switch the sides of the equation. So instead of ending with 81=x, you'll end with x=81.

Answer:

6

Step-by-step explanation:

All you have to do is subtract 16 from both sides!

16+x=22

-16    -16

x=6

I hope this helps, and have a great day! :)

Answer:

the EOQ is 378 units

Step-by-step explanation:

The computation of the economic order quantity(EOQ) is shown below:

EOQ is

[tex]= \sqrt{\frac{2\times A\times O}{C} } \\\\= \sqrt{\frac{2\times 200 \times 50\times \$250}{\$35} }[/tex]

= 378 units

Here A represent the annual demand

O represent the ordering cost

And, C represent the carrying cost

hence, the EOQ is 378 units

Answer:

Use the formula for the trapeze

Step-by-step explanation:

Answer:

∠ C = 88°

Step-by-step explanation:

The opposite angles in a cyclic quadrilateral sum to 180°, then

8x - 4 + 7x + 4 = 180 , that is

15x = 180 ( divide both sides by 15 )

x = 12

Then

∠ C = 7x + 4 = 7(12) + 4 = 84 + 4 = 88°

Answer:

7 1/5 m

Step-by-step explanation:

Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3

Volume of a rectangular prism = Length × Width × Height

Length = Volume/ Width × Height

Length = 60 m³/2 1/2 m × 3 1/3 m

Length = 60 m³/8 1/3 m²

Length = 60 m³÷ 8 1/3 m²

= 60 m³ ÷ 25/3 m²

=( 60 × 3/25 )m

= 180/25 m

Length = 7 1/5 m

it's π 11²-π 3²

π(121-9)

3.14(112)

=351.68cm²

round off yourself (╥﹏╥)

Answer: 150?

Step-by-step explanation:

Answer: 700 customers

Step-by-step explanation:

In a random sample of 200, 140 people ordered French fries.

Find out the percentage of people who ordered French fries:

= 140 / 200

= 70%

If the restaurant usually has 1,000 customers a day, based on the rate of people who ordered French fries out of 200 people - 70% - the number of people who will probably order French fries are:

= 70% * 1,000

= 700 customers

Answer:

12.72 Cents Per Minute

Step-by-step explanation:

Divide 700 by $55 to get the dollars per minute

Answer:

Step-by-step explanation:

let width=x

length=x+7

x(x+7)=30

x²+7x-30=0

x²+10x-3x-30=0

x(x+10)-3(x+10)=0

(x+10)(x-3)=0

either x=-10 (rejected being negative)

or x=3

width=3 cm

length=3+7=10 cm

Perimeter=2(10+3)=2×13=26 cm

Answer:

28

Step-by-step explanation:

x+y=2^6

and we have x=6^2=36

36+y=64(since 2^6= 64)

then,y=64-36=28

so the value of the other number is 28

Answer:

y=-x-5(instead of 5 it could be any number)

Step-by-step explanation:

Answer:

(1,-1)
