Solve the equation−3=8x−4y for y
To solve the equation for y, rearrange the terms and isolate the variable y on one side of the equation.
Explanation:To solve the equation -3 = 8x - 4y for y, we need to isolate the variable y on one side of the equation. First, rearrange the terms:
8x - 4y = -3
Now, move the term with x to the right side by subtracting 8x from both sides:
-4y = -3 - 8x
Finally, divide both sides by -4 to solve for y:
y = (3 + 8x) / 4

Thirty-five percent of 160 is ?
Answer:
56.
Step-by-step explanation:
We are asked to find 35% of 160.
To 35% of 160, we will divide 35 by 100 and multiply the result by 160 as:
[tex]35\%\text{ of 160}=\frac{35}{100}\times 160[/tex]
[tex]35\%\text{ of 160}=0.35\times 160[/tex]
[tex]35\%\text{ of 160}=56[/tex]
Therefore, 56 is 35% of 160.

The brady bunch has three boys who ages are consecutive even integers. The sum of the boy's ages is equal to four times the youngest boy's age. What are the ages Brady boys?
x+x+2+x+4 =4x
3x+6 =4x
x=6
6 +8+10 = 24
ages are 6, 8 & 10
The Brady boys' ages are consecutive even integers, and their respective ages are 6, 8, and 10 years old, as derived from setting up and solving an equation based on the given sum and multiple conditions.
Explanation:We have a mathematical problem involving consecutive even integers and the relationship between their sum and a single integer's multiple. Since the Brady boys' ages are consecutive even integers, we can represent the youngest boy's age as x. The ages of the other two boys would then be x + 2 and x + 4 respectively, because even integers are two units apart.
The information given states that the sum of the boys' ages equals four times the youngest boy's age. This gives us the equation:
x + (x + 2) + (x + 4) = 4x. Simplifying this equation,
3x + 6 = 4x
3x - 4x + 6 = 0
-x + 6 = 0
x = 6.
Therefore, the youngest Brady boy is 6 years old, the middle boy is 8 years old, and the oldest is 10 years old
Which equation represents a line that passes through (4, 1/3 ) and has a slope of 3/4?
y – 3/4 = 1/3(x – 4)
y – 1/3 = 3/4(x – 4)
y – 1/3 = 4(x – 3/4 )
y – 4 = 3/4(x – 3/4 )
Answer:
The correct option is 2.
Step-by-step explanation:
The point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is slope.
The line passes through (4, 1/3 ) and has a slope of 3/4.
The equation of line is
[tex]y-\frac{1}{3}=\frac{3}{4}(x-4)[/tex]
Therefore the correct option is 2.

If 5 rubber stamps cost $9.70 which equation would help determine the cost of 11 rubber stamps
To find the cost of 11 rubber stamps, we calculate the unit price by dividing the given cost of 5 stamps by 5 and then multiply the unit price by 11.
Explanation:To determine the cost of 11 rubber stamps when 5 stamps cost $9.70, first we need to find the cost of one rubber stamp. We divide the total cost by the number of stamps to find the unit price, which is $9.70 ÷ 5 = $1.94 per stamp. Using this unit price, we can then multiply by the desired number of stamps to find the total cost for 11 stamps. The equation to determine the cost of 11 rubber stamps is:
Cost of 11 stamps = 11 × $1.94
By calculating this, we find that 11 stamps will cost $21.34.

Final answer:
300 pounds of water will fill 4.8 cubic feet of space, calculated by dividing the total weight by the weight per cubic foot (300 lb / 62.5 lb/ft³).
Explanation:
The student is asking how many cubic feet of space would be filled by 300 pounds of water, given that water weighs 62 1/2 pounds per cubic foot. To find the answer, we divide the total weight of the water by the weight of water per cubic foot. In this case, we divide 300 lb by 62.5 lb/ft3 (since 62 1/2 pounds is the same as 62.5 pounds).
The calculation will be as follows:
Divide 300 lb by 62.5 lb/ft3.
300 lb / 62.5 lb/ft3 = 4.8 ft3.
Therefore, 300 pounds of water will fill 4.8 cubic feet of space.
