Answer:
20.40
Step-by-step explanation:
Divide 591 by 29 and you will get the answer 20.37. Then, round it up to 20.40.
Answer:
Step-by-step explanation:
Harvey rides his bike at an average speed of 12 miles in 1 hour, 24 miles in 2 hours, and so on. Let h be the number of hours he rides and d be distance traveled. Write the equation for the relationship between distance and time in point-slope form.
----
You have three points relating time and distance:
(1,12),(2,24),(3,36)
-----
The slope for your equation would be (24-12)/(2-1) = 12/1 = 12
-------------------------------
The intercept is the distance you would travel in no time; that would be zero.
---------------------------------
The equation is: distance = 12(time)
d = 12t
You can use cross multiplication here. This is where we multiply the bottoms of the factions with the tops of the other one.
9 moves over to the lop left and 12 to the top right to give
12(4x-15)=9(5x+6)
48x-180=45x+54
3x=234
x=78
Answer:
31
Step-by-step explanation:
From the expression
F(n + 1) = F(n) -3
>> f(n+1)-f(n) = -3
f(n) = f(n+1) + 3
f(4)- f(3) = -3
f(4) + 3 = f(3)
22 + 3 = 25 = f(3)
Similarly ; f(2) = f(3) + 3 = 25 + 3 = 28
f(1)= f(2) + 3 = 28 + 3 = 31
Answer:
-70x, 26y^3, -3z
Step-by-step explanation:
The way to solve this is by combining like terms. The terms we have given to us include x, y^3, and z. As a result, we will group terms based on these variables.
1. Find all the terms with each variable.
* -35x, -35x
* 23y^3, 3y^3
* -3z
2. Combine like terms.
* -35x + (-35x) = -35x - 35x = -70x
* 23y^3 + 3y^3 = 26y^3
* -3z + 0 = -3z
