Answer:

FG = 9

CD = 12

EF = 9

Explanation:

<u>Given</u>:

  • QRSTU ≅ FGCDE

<u>Proportional Sides</u>:

  • GC = 12, RS = 40

<u>Find Scale Factor</u>:

  • 12/40 = 0.3

<u>Find Missing Sides</u>:

1) FG = QR × 0.3 = 30 × 0.3 = 9

2) CD = ST × 0.3 = 40 × 0.3 = 12

3) EF = UQ × 0.3 = 30 × 0.3 = 9

Answer:

See below ~

Step-by-step explanation:

Given :

<u>QRSTU ~ FGCDE</u>

Finding the scale factor :

  • Take two corresponding sides in proportion
  • RS : GC
  • 40 : 12
  • <u>10 : 3</u>

Applying the scale factor to find the missing sides :

- FG :

  • QR : FG = 10 : 3
  • 30/FG = 10/3
  • FG = 30/10 x  3
  • FG = 3 x 3
  • <u>FG = 9</u>

- CD :

  • ST : CD = 10 : 3
  • 40/CD = 10/3
  • CD = 40/10 x 3
  • CD = 4 x 3
  • <u>CD = 12</u>

- EF :

  • UQ : EF = 10 : 3
  • 30/EF = 10/3
  • EF = 30/10 x 3
  • EF = 3 x 3
  • <u>EF = 9</u>

Set it up like a regular equation. I used:
3x+135 \ \textless \  6x

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>x \ \textgreater \  45

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.

What is-3/7x-2 in standard form
Eddi Din [679]
If you are given y = (-3/7)x - 2 and you want it in the form Ax+By = C, then...

y = (-3/7)x-2
7*y = 7*( (-3/7)x-2) ... multiply both sides by 7
7y = -3x-14 ... distribute and multiply
7y+3x = -3x-14+3x ... add 3x to both sides
3x+7y = -14

The standard form equation is 3x+7y = -14

What is the y-intercept -x 3y=9?
dedylja [7]
(0, 3)

<span>-x + 3y=9
to figure out the y-intercept, you must put the equation into y-intercept form first: y = mx + b

</span><span>-x+3y=9
3y = x + 9
y = (x/3) + (9/3)
y = x/3 + 3

Explain in 1-2 sentences how you identify
andrezito [222]

Answer:

You can tell because, as x increases/decreases, y increases/decreases at the same rate EACH TIME. This way, no matter how many times the proportions increase OR decrease, the ratio between x and y always stays the same.
