Find the value of y for which the value of 8y+3 is 7 more than the value of 6yTom and Sam can finish a plowing job in two hours if they work toghether. Tom working alone can do the job in 7 hours. How long would it take Sam to finish the same job alone?
Answer:
19 ; 2.8 hours
Step-by-step explanation:
Find the value of y for which the value of 8y+3 is 7 more than the value of 6y
8y + 3 = 7 + 6y
8y - 6y = 7 - 4
2y = 3
y = 3/2
y = 1.5
Let
Tom's rate = x
Sam's rate = y
Rate = 1 / time
Hence,
x = 1/7
Rate when they work together = 1/2
Tom's rate + Sam's rate = 1/2
1/7 + y = 1/2
y = 1/2 - 1/7
y = (7 - 2) / 14
y = 5/14
Since, rate = 1/time
Time = 1/ rate
Sam's time = 1/ rate = 1/y = reciprocal of y
Sam's time = 14/5 = 2.8 hours
2.8 hours = 2 hours (0.8 * 60) = 2 hours 48 minutes
(7m+3)+(7m+6)
I really need help with this
Answer:
Step-by-step explanation:
The parenthesis can cancel because the lack of anything you can do in them, so that will leave you with 7m + 3 + 7m + 6
Next step is to add like numbers, you should start by adding 7m + 7m, which would be 14m.
Next would be to add 3 + 6, which is nine.
To end this equation, simply put 14m + 9
There is no one-number answer because we do not know what m is. So the equation 14m + 9 is the final answer.
What is the value of x in the following equation?
2/3x+2=4
Answer: 3
Step-by-step explanation: Subtract 2 from both sides, leaving 2/3x=2. All you need to do now is find a number to multiply 2 by to get 6/3, which would be 3. 2=2 is a true statement.
The value of x in the equation (2/3)x + 2 = 4 is x = 3.
We have,
To solve the equation (2/3)x + 2 = 4, we can follow these steps:
- Start by subtracting 2 from both sides of the equation to isolate the term with x:
(2/3)x + 2 - 2 = 4 - 2
(2/3)x = 2
- To get rid of the fraction, multiply both sides of the equation by the reciprocal of (2/3), which is 3/2:
3/2 (2/3)x = 3/2 x 2
x = 3
Therefore,
The value of x in the equation (2/3)x + 2 = 4 is x = 3.

3. Olivia ordered 24 cupcakes and a layer cake. The layer cake cost $16 more than one
cupcake, and the total cost of the order was $53.50. What was the price of each cupcake?
Answer:
$1.50
Step-by-step explanation:
The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes.
This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes )

Jon filled a bucket with 2.7 gallons of water. He used 0.98 gallons for watering his tomato plants and 0.76 gallons for watering his peppers. How much water did he have left in his bucket?
Answer: quantity of water left over = 0.96 gallons
Step-by-step explanation:
Given: Total quantity of water = 2.7 gallons
Water used for tomato plants = 0.98 gallons
Water used for peppers = 0.76 gallons
Total water used = 0.98 +0.76 = 1.74 gallons
Then, quantity of water left over = Total quantity of water - Total water used
= 2.7 - 1.74 gallons
= 0.96 gallons
Hence, quantity of water left over = 0.96 gallons

An angle measures 125.2° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
27.4 and 152.6
Step-by-step explanation:
Supplementary angles equal 180 degrees when placed together.
x+(x+125.2)=180
2x+125.2=180
2x=54.8
x=27.4
the angles are 27.4 and 152.6

An aquarium is being drained. The amount of water in the aquarium, in liters, can be determined by using the function w(x) = 20 - 10 The variable x is the number of seconds after the drain plug is removed. Select EACH true statement about the scenario. The function is a linear equation. The y-intercept of 20 is the initial amount of payater in the aquarium. The slope represents how fast the water is being drained.
Answer:
The answer is all three
Step-by-step explanation:
The function that represents the draining of the aquarium is an illustration of a linear function.
All statements are true about the scenario.
The function is given as:
[tex]\mathbf{w(x) = 20 - 10x}[/tex]
A linear function is represented as:
[tex]\mathbf{y =mx + c}[/tex]
m represents slopec represents the y-interceptBy comparing [tex]\mathbf{y =mx + c}[/tex] and [tex]\mathbf{w(x) = 20 - 10x}[/tex], we can conclude that:
[tex]\mathbf{w(x) = 20 - 10x}[/tex] is a linear equation
The slope of a function is the average rate of a function.
The slope of [tex]\mathbf{w(x) = 20 - 10x}[/tex] is 10
This means that, the aquarium is being drained at a rate of 10 liters per second.
So, we can conclude that, the following statement is also true.
The slope represents how fast the water is being drained.
Lastly, when x = 0, we have:
[tex]\mathbf{w(0) = 20 - 10(0) = 20}[/tex]
This represents the initial volume of the aquarium.
So, we can conclude that, the following statement is also true.
The y-intercept of 20 is the initial amount of water in the aquarium
Hence, the three statements are true.
