A. 1/9
B. -1/5
C. 5/6
D -1/6
Answer:
D, -1/6
Step-by-step explanation:
-1/2+(3/4*4/9)
Multiply equation inside the parentheses
3/4*4/9=12/36=1/3
Substitute 1/3 into original equation
-1/2+1/3=1/3-1/2
Make denominators the same

d=1/2at^2+s, solve for a
Step-by-step explanation:
Perhaps the equation is d=1/2at2 and you are given the distance (40 m) and acceleration (9.8 m/s2) and asked to find the time. or convert the equation in terms of t and then plug in the numbers to solve.
Henry is using a total of 16 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each
4 ft. high. The top, bottom, and two shelves are all the same length, labeled S. How long is each shelf?
Answer: Each shelf is 2ft
Step-by-step explanation:
16 = (2 x 4) + 4s
16 = 8 + 4s
8 = 4s (subtract 8 from both sides)
8/4 = 4s/4 (divide both sides by 4)
2 = s

Step-by-step explanation:
Step 1: Define Equation
3 + 3(x + 2) = -24
Step 2: Solve for x
Distribute 3: 3 + 3x + 6 = -24Combine like terms: 3x + 9 = -24Isolate x term: 3x = -33Isolate x: x = -11Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3 + 3(-11 + 2) = -24Add: 3 + 3(-9) = -24Multiply: 3 - 27 = -24Subtract: -24 = -24Here we see that -24 does indeed equal -24.
∴ x = -11 is the solution to the equation.

Solve the inequality. 2(4x – 3)-3(3x) + + 5x?
Answer:
2 (2 x - 3)
Step-by-step explanation:
Simplify the following:
2 (4 x - 3) - 3×3 x + 5 x
-3×3 = -9:
2 (4 x - 3) + -9 x + 5 x
Grouping like terms, 2 (4 x - 3) - 9 x + 5 x = 2 (4 x - 3) + (5 x - 9 x):
2 (4 x - 3) + (5 x - 9 x)
5 x - 9 x = -4 x:
2 (4 x - 3) + -4 x
2 (4 x - 3) = 8 x - 6:
8 x - 6 - 4 x
Grouping like terms, 8 x - 4 x - 6 = (8 x - 4 x) - 6:
(8 x - 4 x) - 6
8 x - 4 x = 4 x:
4 x - 6
Factor 2 out of 4 x - 6:
Answer: 2 (2 x - 3)

Step-by-step explanation:
Bob wants to make a profit of $1.25 on each fish. How much should he sell each fish for to make this profit? Show your calculation.
note that each fish costs 2.14
Bob would have to sell each fish at $3.39 in order to make a profit of $1.25 on each fish sold
What is the selling price per fish?
The selling price per fish can be determined as the sum of the cost price of $2.14 and the profit per fish which is $1.25, in essence, the selling price in this case is the sum of the cost and profit or alternatively, we can model the profit as the selling price minus the cost price as shown below:
profit per fish=selling price-cost price
profit per fish=$1.25
selling price=unknown
cost price=$2.14
By making the selling price the subject of the formula, we can determine the selling price using the formula above
$1.25=selling price-$2.14
selling price=$2.14+$1.25
selling price=$3.39

Abbey receives a $40 gift card for downloading music and wants to determine how many songs she can purchase. Each downloaded song costs $2.89 a. Let m represents the number of songs downloaded. Write an inequality that represents this given situation? b. What is the maximum number of songs Abbey can download?
Answer:
A. $2.89(m)=$40
B. 13 songs
Step-by-step explanation:

Step-by-step explanation:
40 divided by 2.89 is 13.84. DO NOT ROUND TO 14
So its a maximum of 13 songs, otherwise it will cost 40.46 for 14 songs
