To solve this problem, we first have to combine the two fractions on the left side of the equation. To do this, we must make a common denominator of 8. Because 8/8 is equal to 1, we can substitute this value into the equation:
3x/8 - 8/8 = 5/8
Next, we can subtract the fractions on the left side of the equation to simplify. Remember that if fractions have the same denominator, we simply subtract their numerators and keep the difference over the common denominator.
3x - 8/8 = 5/8
Since both sides of the equation have a denominator of 8, we can cancel out this denominator on both sides by multiplying both sides by 8. This gives us:
3x - 8 = 5
Next, we should add 8 to both sides of the equation so that we can get all of the constants to the right side of the equation.
3x = 13
Finally, we should divide both sides by 3 to get the variable alone on the left side of the equation.
x = 13/3
Therefore, your answer is x = 13/3.

Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.

the answer is 15 loads of gravel because 3 times 2 equals 6 which means 3 * 5 is equal to 15
