Solve the following equation for X.
2x - 18y = - 8
Answers
Answer:
x = 9y - 4
Step-by-step explanation:
2x - 18y = - 8 /: 2
x - 9y = - 4
x = 9y - 4

Question Continuation
if the measured weight of lead in the sample is
a.) 764.9g lead
b.)226.3g lead
c.) 53.5g lead
Answer:
a.
Relative Error = 0.065
b.
Relative Error = 0.221
c.
Relative Error = 0.935
Step-by-step explanation:
Given
Absolute Error = 0.5g
Relative error = absolute error/magnitude of measurement.
Relative error % = Relative error * 100
a.
Relative Error = 0.5/764.9 * 100
Relative Error = 50/764.9
Relative Error = 0.065
b.
Relative Error = 0.5/226.3 * 100
Relative Error = 50/226.3
Relative Error = 0.221
c.
Relative Error = 0.5/53.5 * 100
Relative Error = 50/53.5
Relative Error = 0.935
Final answer:
In Chemistry, the percent relative error is calculated by taking the absolute value of the error divided by the original measurement, and then multiplying by 100%. In this case, for a measured value of lead, the percent relative error would be (0.5 g / measured mass) * 100%.
Explanation:
The percent relative error in any measurement is calculated by taking the absolute value of the error divided by the measured value, all multiplied by 100% to get the result in percent forms. In this case, the absolute error is always 0.5 g (which means the values are consistently 0.5 g less than expected). The percent relative error would be calculated as follows:
- For a measured value, say M grams, the percent relative error would be (0.5 g / M) * 100%.
Keep in mind, the relative error varies with each measured mass. Therefore, for each different measured mass of lead, you would substitute that value in place of M in the above formula to calculate the respective percent relative error.

Let y be that of cars manufactured per day in county B.
x+y= 39,612
but x= 5y..... equation (1)
So: 5y+y= 39,612
6y= 39,612
y= 6,602 cars
Substitute y= 6,602 in equation (1):
x= 5(6,602)
x= 33,010
So the number manufactured in county A is 33,010 cars and the number manufactured in county B is 6,602 cars.
Final answer:
By using proportions and basic arithmetic, we find that country B produces 6602 cars per day and country A produces 33,010 cars per day.
Explanation:
The problem here is based on proportions. Since it is given that country A produces about five times as many cars as country B, if we denote the number of cars produced in country B as 'x', then the number of cars produced in country A would be '5x'.
According to the problem, the total number of cars produced in both countries is 39,612. Hence, we can set up the equation x + 5x = 39612, which simplifies to 6x = 39612. To find the value of 'x', we divide both sides of the equation by 6. The resulting value of 'x' (the number of cars produced in country B) is 6602 cars. Multiply this by 5 to find the number of cars produced in country A, which comes up to 33,010 cars.
