Answer:
a) T = 25n + 40
b) T = $415
Step-by-step explanation:
The total cost of 'n' kilograms of something can be expressed as 'n' multiplied by the cost, since it is a constant cost per unit. Therefore the price for n kg of potatoes can be expressed as 25n. We are also told that a dozen bananas cost $40, so our expression is the cost of potatoes added to the cost of bananas. So, is we use 'T' for total cost, our expression will look like this:
T = 25n + 40
Now we can use this expression to find the cost of 15kg of potatoes and the same amount of bananas. We can do this by simply substituting the given amount for n:
T = 25(15) + 40
T = 375 + 40
T = $415
The cost of 15kg of potatoes and one dozen bananas is $415.

Evaluate 3ab for a=2 and b=3
Answer:
18
Step-by-step explanation:
For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.
a = 2; b = 3
3ab
Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.
3ab = 3 * a * b
With this in mind, let's plug in the values of a and b into the expression.
3ab
= 3 (2) (3)
= 3 (6)
= 18
Hence, 3ab evaluated when a=2 and b=3 is 18.

Answer:
11. a) 912. c) 013. c) -1/214. d) -3Step-by-step explanation:
11.
-3(x - 11) = 6x - 11 = -2x = 11 - 2x = 912.
-7x/9 + 2 = 2-7x/9 = 0x = 013.
-8x + 2 = 6-8x = 4x = 4/(-8)x = -1/214.
4x - 5 = -174x = 5 - 174x = -12x = -12/4x = -3Diana wanted to make peanut brittle for a holiday party, so she bought a 16.5-ounce jar of peanuts at the grocery store. She used 3 5 of the peanuts to make peanut brittle. The next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends. How many ounces of peanuts did Diana put in each bag of trail mix?
Answer:
2.2 ounces.
Step-by-step explanation:
Quantity of peanuts Diana bought = 16.5 ounces
Quantity used for peanut brittle = 3/5
Hence:
3/5 × 16.5
= 9.9 ounces was used for peanut brittle.
The amount left =
16.5 ounces - 9.9 ounces
= 6.6 ounces.
We are told that: the next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends.
The ounces of peanuts she put in each bag of trail mix is calculated as:
6.6 ounces ÷ 3 bags
= 2.2 ounces.

Solve the equations 7(2x+6)=1
Answer:
Step-by-step explanation:
B
Answer:
x = - [tex]\frac{41}{14}[/tex]
Step-by-step explanation:
Given
7(2x + 6) = 1 ← distribute parenthesis on left side
14x + 42 = 1 ( subtract 42 from both sides )
14x = - 41 ( divide both sides by 14 )
x = - [tex]\frac{41}{14}[/tex]

O
Answer:
A
Step-by-step explanation:
The coach will most likely count this as an expense and will want to overestimate so that he is certain to have all the golf balls for his lessons. If he underestimates, he will not be able to have all his balls.
A. It is better to overestimate to make sure the coach has enough money to buy the golf balls.
What is over and under estimating ?Over estimating is when we set a higher amount than we need in case of price increase and the item is a must buy.
Underestimating when we set a lower amount than needed when money is of more concern and the item is not a must buy.
According to the given question At the beginning of the season, a golf coach buys 118 sleeves of golf balls. Each sleeve costs $8.
It is always better to overestimate and if some amount remains then it can be used later.
So, It is better to overestimate to make sure the coach has enough money to buy the golf balls to continue his lessons without any interruption underestimating will lead to less golf balls and interrupted golf sessions.

Find the value of x.
Area of rectangle = 36
▅ х
x + 5
The value of x is 4, which is determined by the quadratic equation.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The rectangle of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that area of the rectangle = 36
Area of rectangle = width of the rectangle × length of the rectangle
Here the width of the rectangle = x
And length of the rectangle = x + 5
The rectangle of a rectangle = x × (x + 5)
36 = x² + 5x
x² + 5x - 36 = 0
x² + 9x - 4x - 36 = 0
(x + 9)(x - 4) = 0
x = -9 and x = 4
Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.
Therefore, the value of x is 4.
