Answers

Answer:

Simplifying

7x = 33

Solving

7x = 33

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '7'.

x = 4.714285714

Simplifying

x = 4.714285714

Step-by-step explanation:

7x = 33

divide both sides by 7

x = 33/7

this fraction cannot be simplified so you can either leave it as

x=33/7

farmer has 120 bushels of wheat to sell at her roadside stand. She sells an average of 16
5
8 bushels each day. Represent the total change in the number of bushels she has for sale after 5 days.

Answers

Answer:

The total change in the number of bushels she has for sale after 5 days is 83.125 bushels

Step-by-step explanation:

The given parameters are;

The initial number pf bushels the farmer has = 120 bushels

The amount of bushels of wheat the farmer sells each day = 16⁵/₈ = 16.625

The number of bushels sold after 5 days = 16.625 × 5 = 83.125 bushels

The total change in the number of bushels she has for sale after 5 days = The number of bushels sold after 5 days

The total change in the number of bushels she has for sale after 5 days = 83.125 bushels.

Solve for c.

Answers

[tex]a(c - b) = d[/tex]

Divided sides by a

[tex] \frac{a}{a}(c - b) = \frac{d}{a} \\ [/tex]

[tex]c - b = \frac{d}{a} \\ [/tex]

Plus sides b

[tex]c - b + b = \frac{d}{a} + b \\ [/tex]

[tex]c = \frac{d}{a} + b \\ [/tex]

Done.....♥️♥️♥️♥️♥️

Answer:

[tex]c = \frac{ab + d}{a}[/tex]

Step-by-step explanation:

Step 1: Add ab to both sides.

−ab + ac + ab = d + ab

ac = ab + d

Step 2: Divide both sides by a.

[tex]\frac{ac}{a} =\frac{ab + d}{a}[/tex]

[tex]c = \frac{ab + d}{a}[/tex]

An angle measures 38° less than its complement. Find the measures of the two angles.​

Answers

Let c represent the complement.

angle = c - 38
Complement = c

equation :

c - 38 + c = 180
2c - 38 = 180
2c = 218
c = 109

First angle is 71 degrees and the complement is 109.

The measures of the angles are: 64°  and 26°.

Recall: Two angles are complement of each other if they add up to the sum of 90° .

Thus,

Let [tex]x[/tex] represent the first angle

The second angle = [tex](x-38)^{o}[/tex]

Therefore:

[tex]x + (x - 38) = 90[/tex]

Solve for x

[tex]x + x - 38 = 90\\2x - 38 = 90\\2x - 38 + 38 = 90 + 38\\2x = 128\\x = 64[/tex]

The first angle, x, is 64°

The second angle = [tex]x - 38[/tex]

Plug in the value of x

[tex]= 64 - 38\\= 26[/tex]

Therefore, the measures of the two angles are 64°  and 26°

£880 is divided between Pip, Sara & Gordon so that Pip gets twice as much as Sara, and Sara gets three times as much as Gordon. How much does Sara get?
I don’t know how to work this out

Answers

Answer:

Assume Gordon got X dollar

Then

sara got = 3*x= 3x

Pip got = 2*3x= 6x

Now,

x + 3x + 6x = 880

10x =880

x= 88

Sara got = 3x = 3*88 = 264

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place

please don't answer if you are wrong

Answers

Answer:

38.3

Step-by-step explanation:

The perimeter of the figure can be broken down into the perimeter of 3 sides of the parallelogram, and the perimeter of the semicircle (without its diameter).

The three sides of the parallelogram would be 14+14+4=32.

The perimeter of the semicircle would be 1/2*diameter*pi, which is about 1/2*4*3.14=6.28.

Therefore, the perimeter is 32+6.28=38.3 (to the nearest tenths).
