Answer:
x = 3/7y - 13/7
Step-by-step explanation:
7x-3y=-13
+3y +3y Add 3y to both sides
7x = 3y - 13 Divide both sides by 7
x = 3/7y - 13/7
Answer:
it is a right triangle
Step-by-step explanation:
confirm if it is a right triangle using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
12² + 35²
144 + 1225 = 1369
square toot of 1369 is 37
so
12² + 35² = 37²
You can divide 1000 by 4 then multiply a number to get 2500
1000/4= 250
250 x 10 = 2500
