10. Weiming and Joyce intend to buy a present for Siti. Weiming agrees to pay at least twice as much as but at most $150 more th
djverab [1.8K]

The  required amount Weiming has to pay is given by the limit of $150

more than the amount Joyce has to pay.

Response:

  • The greatest amount Weiming has to pay is<u> $180</u>

<h3>Which method can be used to analyze the amount paid by Weiming and Joyce?</h3>

Amount Weiming agrees to pay ≥ 2 × Joyce agrees to pay

Amount Weiming agrees to pay ≤ 150 + Amount Joyce agrees to pay

Let <em>x</em> represent the amount Weiming agrees to pay, and let <em>y</em> represent

the amount Joyce agrees to pay, we have;

x + y = 210

x ≥ 2·y

x ≤ y + 150

When the amount Weiming is $150 more than Joyce, which is the

limiting amount for Weiming, we have;

x = y + 150

Which gives;

y + 150 + y = 210

2·y = 210 - 150 = 60

y = 60 ÷ 2 = 30

x = 30 + 150 = 180

Therefore;

  • The greatest amount Weiming has to pay is, x = <u> $180</u>

Please help thank you so much
Licemer1 [7]

Answer:

\Huge\boxed{x=15}

Step-by-step explanation:

Hello There!

The angle labeled 6x is a right angle

If an angle is formed using the diameter of a circle then the opposite angle of that side is a right angle

So 6x = 90

isolate the variable

divide each side by 6

90/6= 15

6x/6=x

we're left with x = 15
