The number may be written as
![720,080 \\ = \frac{720,080}{100,000} \times 100,000 \\ =7.2008 \times 10^{5}](https://tex.z-dn.net/?f=720%2C080%20%5C%5C%20%3D%20%20%5Cfrac%7B720%2C080%7D%7B100%2C000%7D%20%5Ctimes%20100%2C000%20%5C%5C%20%3D7.2008%20%5Ctimes%2010%5E%7B5%7D)
Answer: 7.2008 x 10⁵
A) 32 sticks
Each time 5 sticks are added. So pattern 6 would have 25 stickers added to the original 7 sticks equaling 32 sticks
B)n=5x+7
9514 1404 393
Answer:
Step-by-step explanation:
If find that "substitution" works well for "mixture" problems like this. Usually, you will want to substitute for the lower-priced item, so that you're solving for the number of higher-priced items.
Let "a" and "k" stand for the number of adult and kid tickets, respectively.
a + k = 54 . . . . . . total number of tickets sold
8a +5k = 360 . . . total revenue
__
To substitute for k, we solve the first equation for k:
k = 54 -a
Now, we substitute that into the second equation:
8a +5(54 -a) = 360
3a = 90 . . . . . . . . . . . subtract 270 from both sides; collect terms
a = 30 . . . . . . . . . . . . divide by 3
k = 54 -30 = 24 . . . . . use the above formula for k
The number of kids was 24; the number of adults was 30.
Answer:
I. C
II. A, D
III. B
Lines that coincide have infinite solutions, and parallel lines have no solutions.
Step-by-step explanation:
3. To solve this equation, look at the slopes of the equation. The equations are in y=mx+b form. m is equal to the slope.
Equations with different slopes will have one solution, meaning that the lines will intersect once.
Equations with the same slope will either have no solutions or infinite solutions. <u>If the equations are the exact same</u>, it will have infinite solutions, meaning that the line "intersects" itself in infinite places since its basically one line right on top of another. <u>If the equations have different y-intercepts</u>, it will have no solutions because the lines are going at the same angle, are parallel and will never intersect.
This means that A and D have one solution, B has infinite solutions, and C has no solutions.
4. Lines that coincide have infinite solutions, and parallel lines have no solutions.
