let L = length and let W = width.

Use the equations 2L + 2W = 2750

and L = 5W + 15

Then do the steps as follows -

1. Plug the equation for what L equals into the first equation

2(5W+15) + 2W = 2750

2. Then distribute the 2

10W + 30 + 2W = 2750

3. Then add like terms

12W + 30 = 2750

4. Then subtract 30 from both sides

12W = 2720

5. Divide by 12 on both sides

W = 226.67

6. Then plug that into the second equation

L = 5(226.67) + 15

L = 1148.35 should be the answer

1. If RU = 16, UT = 20, and SR = 16, what is the perimeter of SUT?
nlexa [21]

Answer:

72

Step-by-step explanation:

If SR and RU have the same length, a right angle, and a shared side, we know that they are congruent triangles using SAS (Side Angle Side). Our equation to find the perimeter would be SR + RU + UT + TS or 16 + 16 + 20 + 20(using our knowledge of the congruent triangles) = 72.

Find the value of x.<br> 4<br><br> 14<br><br> 3<br><br> 6
nadezda [96]

Hello from MrBillDoesMath!

Answer:

4

Discussion:

As vertical angles are equal,    Angle 3 = Angle 2,  so

Angle 3 = 3x + 2     (A)

Angles 3 and 7 are corresponding angles and hence equal. So

Angle 3 = Angle 7   =>  use (A) above and Angle 7 =  x + 10

3x + 2 = x + 10  =>   subtract x from both sides

3x -x + 2 = x - x + 10  =>

2x + 2 = 10                 => subtract 2 from both sides

2x = 10 -2 = 8

x = 8/2 = 4


which is the first choice



Thank you,

MrB
