If RV=w and SU=w–30, what is the value of w?

Mathematics
1 answer:
gtnhenbr [62]2 years ago
5 0

Answer:

w = 60

Step-by-step explanation:

the midsegment SU is half the measure of side RV , then

SU = \frac{1}{2} RV , so

w - 30 = \frac{1}{2} w ( multiply through by 2 to clear the fraction )

2w - 60 = w ( subtract w from both sides )

w - 60 = 0 ( add 60 to both sides )

w = 60

Mazyrski [523]

Answer:

Length=9.6 cm\\\\Width=4.8 cm

Step-by-step explanation:

Length=2*Width

L=2*W

Perimeter=28.8 cm

Perimeter of a rectangle= 2(Length+Width)

28.8=2(2W+W)\\\\28.8=2(3W)\\\\3W=28.8/2\\\\3W=14.4\\\\W=14.4/3\\\\W=4.8 cm\\\\

Length=2*Width\\\\=2*4.8\\\\=9.6 cm\\\\

Length=9.6 cm\\\\Width=4.8 cm

Suppose you are a salesperson for
Sliva [168]

Answer:

27,000$ worth of sales

Step-by-step explanation:

What you need to earn - what you earn monthly = 1/6 of the amount you need to sell.

4000 - 2200 = 1800

1800 is ONE fifteenth of the sales.

1800 * 15 = 27,000.

You must sell MORE than $27,000 worth of sales in order to earn more than $4000.

uysha [10]
That point does not satisfy either inequality. 

You can tell it does not satisfy the first portion, due to it being under the shaded line. Secondly, the dotted line goes through it, but that fact that it is dotted makes it not included.
