Pleaseeeeeeeee helpppp...

zvonat [6]

Answer:

x = 67

Step-by-step explanation:

∠ CRQ = ∠ BQR = 113° ( Alternate angles )

∠ CRQ and ∠ CRS are adjacent angles and supplementary, that is

x + 113 = 180 ( subtract 113 from both sides )

x = 67

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will i

Hatshy [7]

Answer: 3 weeks

Step-by-step explanation:

We have to note firstly that 12 inches = 1 foot.

The equation given to represent the height in the question, h = 3w + 3.

The number of weeks that it will take the plant to reach one foot will then be:

h = 3w + 3

12 = 3w + 3

3w = 12 - 3

3w = 9

w = 9/3

w = 3

It'll take 3 weeks

Write an expression to model the perimeter of the rectangle. Length is x-9 and width is 3x-4. Part b The perimeter of the rectan

koban [17]

Step-by-step explanation:

To find the perimeter of something, we add all of the measurements of the sides together.

A rectangle has 4 sides, this means we must double the algebraic hints given to us.

If we add them all up together it will look like this:

x-9+x-9+3x-4+3x-4=138

If we simplify it by collecting the like terms:

8x-26=138

We add 26 onto 138

8x=164

To find out what x equals, we divide by 8:

164÷8= 20.5

Answer:

x=20.5cm

x-9 is 11.5

3x-4 is 57.5

I know that you will not give 100 points but just wanted to help.

12 is 90% of what number?<br><br><br> with steps

a_sh-v [17]

Answer:

<h3><u>Let's</u><u> </u><u>understand the concept</u><u>:</u><u>-</u></h3>

Here 12 is 90% of a number.
So we can say that 90% of That number is 12 .
In this way we can get the the number

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Let,

the number=x

<h3>According to the question ,</h3>

${:}\longrightarrow$ $\sf 90\% \:of \;x=12$

We know 90%=90/100
so add it

${:}\longrightarrow$ $\sf {\dfrac {90}{100}}\times x=12$

${:}\longrightarrow$ $\sf {\dfrac {90x}{100}}=12$

Now use cross multiplication method

${:}\longrightarrow$ $\sf 90x=12\times 100$

${:}\longrightarrow$ $\sf 90x=1200$

Now interchange sides .

${:}\longrightarrow$ $\sf x={\dfrac {1200}{90}}$

${:}\longrightarrow$ $\sf x={\dfrac {200}{15}}$

Answer will come in decimals so we take approximate value.

${:}\longrightarrow$ $\sf x=13.3$

${:}\longrightarrow$ $\sf x=approximately \:13$

$\therefore$ The number is 13.
