-15+2 means you add 2 to the negative number 15 so -15+2 will give us -13 which is the answer.
You have 45 1/3 pizzas for a party. You have to split this 6 people per pizza. How many people can eat?
272 x 1/6 = 45 1/3
These three numbers can all be moved around. With different functions, two of them will always equal the third.
Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
Answer:
40 mm
Step-by-step explanation:
It's 40 mm because the Pythagorean Theorem explains a^2 + b^2 = c^2.
This means the unknown number plus 30^2 = 50^2
What you want to do is 50^2 - 30^2= 20^2; which would be 2500-900=1600.
You got 1600 but that isn't your final answer. You want to find the square root 1600. So 1600 square rooted is 40.
40 mm is your final answer.
