Answer:
You would use a^2 + b^2 = c^2
Step-by-step explanation:
a and b are the shorter side of the triangle whereas c is the hypotenuse or longest side of the triangle
Answer:
x = 4 , y = -1
Step-by-step explanation:
x - 3y = 7 -- (1)
3x - 3y = 15 -- (2)
Rewriting (1), x = 3y + 7 -- (1)'
Substituting (1)' into (2),
3 ( 3y + 7 ) - 3y = 15
9y + 21 - 3y = 15
6y = -6
y = -1 -- (3)
Substituting (3) into (1),
x - 3 ( - 1 ) = 7
x + 3 = 7
x = 4 -- (4)
According to (3) and (4),
x = 4 , y = -1
Answer:
B
Step-by-step explanation:
x% of 6 = 5.25
x 6 = 5.25
= x
x = 87.5 %
discount = 100 - 87.5 %
= 12.5 %
If I’m getting this right the equation is: 0.00045 - 2.5 x 10 - 5? The dot in between 2.5 and 10 indicates a multiplication sign
So...
0.00045 - (2.5 x 10) - 5
0.00045 - 25 - 5
= -29.9999 -> -30
