One equation that represents this statement above me could be: <span>4r + 3 (10-r) = 37.
</span>How? R = Rollercoaster - B = Boat Rides
r + b = 10
37 tickets were spent so..
4*r + 3*b = 37
We just multiplied the number of rides on roller coasters and the boats with the price of both.
Now we have to express boat rides from the first equation:
b = 10-r, and express that in the second equation, now we get:
4r + 3(10-r) = 37, which is the answer.
Answer:
The domain of the function is 0 less-than-or-equal-to x less-than infinity ⇒ 3rd answer
Step-by-step explanation:
The domain of the function f(x) = y is all the values of x which make the function defined
∵ 
- There is no square root for negative number, that means x
must be non-negative number
∵ The non negative numbers start from zero till infinity
∴ 0 ≤ x < ∞
∴ x must be greater than or equal zero and less than infinity
- Values of x are the domain of the function
∴ The domain of the function is 0 ≤ x < ∞
The domain of the function is 0 less-than-or-equal-to x less-than infinity
Answer:
The missing number is 150
Step-by-step explanation:
45 + 5= ? -100
To carry out the problem we are going to call x to (?)
45 + 5= x -100
we see that we have a -100 of the second side of the equality, to get it out of there we can add 100 in both parts of the equality
45 + 5 + 100 = x -100 + 100
now we just solve and we have left
45 + 5 + 100 = x
As we see this is a common sum, by which we can already add it and obtain the value of x
150 = x
If a right angle is bisected, <em>complementary angles</em> are formed. Complementary Angles are angles that <u>add up to 90°, which is also known as the right angle.</u>
Answer:
