Answer:
Brenda
Step-by-step explanation:
You can divide the number of pages by the number of minutes to find the amount of minutes it takes to read 1 page. For Arnold, 3 pages / 7 minutes = 1 page per approximately 0.43 minutes. For Brenda, 8 pages / 14 minutes = 1 page per approximately 0.57 minutes. Brenda reads slightly faster since 0.57 > 0.43
Pythagoras' Theorem
a^2+b^2=c^2
c is the longest side of the triangle
a and b are the other two sides
In a right angled triangle:
the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
If one angle is 80 degrees we can assume that each other angle must be 80, 100, and 100 degrees.

Answer:
30
Step-by-step explanation:
Equation y = 3x + 210
if y = 10x
10x = 3x + 210
or, 10x - 3x = 3x + 210 - 3x
or, 7x = 210
or, x = 210 ÷ 7
or, x = 30
