Answer:
Our final equation is
Step-by-step explanation:
We are given a coordinate point and the slope of a line. We need to know that:
- The slope-intercept form of a line is where <em>m</em> is the slope of the line and <em>b</em> is the y-intercept of the line.
- The point-slope formula is y - y₁ = m(x - x₁).
We want to end up at the slope-intercept form of the equation. Therefore, we can use the point-slope formula and substitute our values and solve the equation.
Therefore, we have determined that our equation in slope-intercept form is .
We can quickly solve this problem by assigning hypothetical values. Suppose we let Jolie's marbles equal to 100. This would mean that Mary will have 60 since 40% of 100 is 40.
The percentage of all marbles that are Jolie's could be solved by dividing Jolie's hypothetical number of values with the total hypothetical sum of Jolie and Mary's marbles.
ANSWER: 62.5% of the marbles in the bag are Jolie's.
Answer:
9 hours
Step-by-step explanation:
10 portraits in 30 hours, let's write it mathematically
10p=30h then 1p=(30/10)h= 3 h three hours for a single portrait
therefore for 3 portraits he will take three times 3 hours
3p=3*3h = 9 hours
Answer:
Sugars
Step-by-step explanation:
This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. Sugars are particularly important fuel molecules.
