Answer:
Avg speed of the round trip = 2*10*2/(10+2) = 10/3 mi/hr
D = r*t = (10/3)*6 = 20 miles
--> 10 miles each way
--> 5 hours walking back.

Solve 5ax + 3ax = 4ax + 12 for x. Assume a ≠ 0.
Answer:
c. 3/a
Step-by-step explanation:
5ax + 3ax = 4xa+ 12, combine like terms
8ax = 4ax + 12, minus 4ax on both sides
4ax = 12, divide 4a on both sides
youll be left with x = 3/a

Answer:
-6
Step-by-step explanation:
TO find the slope pick two points and do y2 - y1 / x2 - x1
I picked the first two:
2 - 8/ -1 - -2 = -6/ 1 = -6
The slope of the given line is - 6 as per slope-intercept form.
What is the slope of a straight line?The linear equation y = mx + c represents the slope-intercept form of a line passing through the point (x, y).
Here, 'm' is the slope and 'c' is the y-intercept of the given line.
The slope of a line that passes through points (x₁, y₁) and (x₂, y₂) is defined as:
m = (y₂ - y₁)/(x₂ - x₁)
Therefore, the slope of a line that passes through (-2, 8) and (-1, 2) is
= (2 - 8)/[- 1 - (- 2)]
= - 6/1
= - 6

Step-by-step explanation:
On the left side, we have 3 people pulling with a force of 50n. That makes the total force 150. On the right side, we have 2 people pulling with 75n force which makes the total force 150n ad well. If the force is the same on each side then the rope cannot move. If they force on one of the sides was greater than the rope would move to that side
-Hope this helps
Answer:
I would say it will move to the ( Right ) because even tho there’s more students on the left there is also more force to the right making the right side have the most force.
Step-by-step explanation: so the answer is it will move to the right because of the higher force.

Brady drew a rectangle with an area of 35.52 square centimeters. Staci drew a rectangle with an area of 61.44 square centimeters. How many more square centimeters is Staci's rectangle than Brady's? A. 25.08 square centimeters B. 25.92 square centimeters C. 26.08 square centimeters D. 26.82 square centimeters
Answer:
B. 25.92 square centimeters.
Step-by-step explanation:
Brady's rectangle has an area of 35.52 cm^2
Staci's rectangle with area of 61.44 cm^2
So, Staci's rectangle is 61.44 -35.52 cm^2 more than Brady's.
Let's simplify it,
It gives 25.92 cm^2

WHY must the same operation be performed on both sides of an equation?
Answer:When you are given a problem, the two sides are equal, so they are equally weighted. As long as you do the same thing on both sides, they remain the same weight. The only way that one side can become "more weight" on a side is if you make a math mistake, and thus the answer would not satisfy the original equation

Helpppppp meeeeeeee help mee
Step-by-step explanation:
29x - 3 + 15x + 7 = 18 because these two angles are supplementary
29x + 15x + 7 - 3 = 18044x = 176 divide both sides by 44x = 413y - 17 = 29x - 3 because these two angles are alternate
since we know the value of x
13y - 17 = 29 × 4 - 313y - 17 = 11313y = 113 + 1713y = 130 divide both sides by 13y = 10A librarian wants to spend no more than $800 on some new desks and chairs for the library. The librarian decides to spend $320 on desks.
If each chair costs $24, what is the maximum number of chairs the librarian can buy for the library and stay within the budget?
Answer:
I think 20
Step-by-step explanation:
480/24
The maximum number of chairs that the librarian can buy is 20
What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which :
s represents = the number of chairs,
and we simply solve for s.
800 = 320 + 24s ... subtract both sides by 300
500 = 24s ... divide both sides by 24
20.83 = s
Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.
