Unicycle has 1 seat and 1 wheel.
Bicycle has 1 seat and 2 wheels.
u + b = 21
u + 2 b = 30 ⇒ u = 30 - 2 b
--------------------------------------
30 - 2 b + b = 21
30 - b = 21
b = 9, u = 30 - 18 = 12
There are 12 unicycles and 9 bicycles.
An equation in slope-intercept form:
u + b = 21
u = - b + 21
Answer: A ) u = - b + 21
Answer:
3/1, or 3
Step-by-step explanation:
When you have a perpendicular line, if it is a negative, you take away the negative, and if it is a fraction, you turn it upside down. 1/3 becomes 3/1.
It’s 18 for sure it’s pretty simple
<span>We can quickly calculate a ten percent tip by moving the decimal place one to the left. So a 10% tip on $85.00 would be $8.50. We can then take half of that tip to calculate the remaining 5%. $8.50 / 2 = $4.25. The sum of these two results is equal to a 15% tip. $8.50 + $4.25 = $12.75. The correct answer is D.</span>
Answer:
No
4x squared + 8x + 3 =
4x squared: 16x
16x + 8x + 3
add 16 and 8 = 24x + 3 and that's your answer
