Answer:
7.21 unit
Step-by-step explanation:
distance= √[(-7+3)^2 + (-6-0)^2]
= 7.21 unit
The answer would be D. D is the correct answer because the x which is 100 is equal to the amount of U.S dollars and H(x) is equal to the amounts of euros. So H(100)= 75 can signify that she can exchange 100 U.S dollars for 75 euros.

<u>Answer</u>:
x = 7, y = 2
<u>Explanation</u>:
equations given:
x + 7y = 21
x + 4y = 15
make "x" the subject:
x + 7y = 21
x = 21 - 7y .........equation 1
x + 4y = 15
x = 15 - 4y .......equation 2
Solving both the equations simultaneously:
15 - 4y = 21 - 7y
-4y + 7y = 21 - 15
3y = 6
y = 6 ÷ 3
y = 2
If y is 2
Then x = 21 -7y;
x = 21 - 7(2)
x = 21 - 14
x = 7
Answer:
30°, 45° and 105°
Step-by-step explanation:
2 + 3 + 7 = 12 parts
180/12 = 15 degrees each part
First angle (2 parts)
2(15) = 30°
Second angle (3 parts)
3(15) = 45°
Third angle (7 parts)
7(15) = 105°
