a laptop that was originally priced at $650 was placed on sale for 25% off. when it did not sell it was put on clearance for 30% off the sale price. what was the clearance price of the laptop
Answer:
$48.75
Step-by-step explanation:
To find 25% of 650 you find 50%. To do this you divide 650 by 2 which is 325. you then divide that by 2 again to get $162.50. That is the sale price.
You now need to find 30% of 162.50. To do that you find 10% 3 times because 10x3 is 30. To find 10% you divide 162.50 by 10 to get 16.25.
16.25x3 is $48.75 which is our answer.

the hcf and lcm of 180, 150 and 315
Answer:
HCF=15 LCM=6,300
Step-by-step explanation:
Answer:
HCF = 15
LCM = 6300.
Step-by-step explanation:
Write them out as a product of their prime factors:
180 = 2*2*3*3*5
150 = 2*3*5*5
315 = 3*3*5*7
Picking out the factors common to all 3 list of prime factors:
The GCF = 3*5 = 15.
To find the LCM we pick out all the numbers except if there are repeated number we only use them once, So for example we only take 2*2 for the calculation as there is a pair of 2's in 180 and 150 factors and there is an extra 2 in 180 - so we only take 2 of the 3 2's.
LCM = 2 * 2 * 3 * 3 * 5 * 5 * 7
= 6300.

Answer:
A solution of a system of equations is a list of numbers x , y , z ,... that make all of the equations true simultaneously. The solution set of a system of equations is the collection of all solutions. Solving the system means finding all solutions with formulas involving some number of parameters.
Step-by-step explanation:
hope it will help you
Answer:
Step-by-step explanation:
In this context "solution" means a point whose x- and y-coordinates satisfy both equations.
If we're given the two linear equations x + y = 3 and 2x - y = 7, we can solve them by addition and subtraction (among other methods):
3x = 3 + 7, or 3x = 10, or x = 10/3.
Substitute this result into x + y = 3 to find the corresponding y value;
10/3 + y = 3, or 10/3 + y = 9/3, or y = 1/3.
Then the "solution" is the point (10/3, 1/3).
At Tower Middle School, there are 14 girls and 16 boys in Mr. Bell's class. There are 17 girls and 19 boys in Ms. Carlson's class. Which of the following best compares Mr. Bell's and Ms. Carlson's classes?

They have the same ratio of girls to boys because a straight line can be drawn through the points (14,16) and (17,19) on a coordinate grid.
B.
They have the same ratio of girls to boys because a straight line can be drawn through the points (14,16), (17,19), and (0,0) on a coordinate grid.
C.
They do not have the same ratio of girls to boys because a straight line cannot be drawn through the points (14,16) and (17,19) on a coordinate grid.
D.
They do not have the same ratio of girls to boys because a straight line cannot be drawn through the points (14,16), (17,19), and (0,0) on a coordinate grid.
Answer:
D. They do not have the same ratio of girls to boys because a straight line cannot be drawn through the points (14, 16), (17, 19), and (0, 0) on a coordinate grid.
Step-by-step explanation:
In order to check if the ratio is the same, convert the ratios to (x, y) points, plot them on a graph and see if you can draw a straight line through them and the origin (0, 0). If you can, then the ratios are the same. If not, then the ratios are not the same.
After plotting (14, 16) and (17, 19) and (0, 0) on a graph (attached), you can see that a straight line will only go through any two of the points, but not all three. Therefore, the ratios are not the same.
4/7

What is the number?
[tex]\text{If the number is x,}\\\\~~~~~\dfrac 47 \cdot x =36\\\\\implies 4x = 36 \times 7\\\\\implies x =\dfrac{36 \times 7}4\\ \\\implies x = 9 \times 7\\\\\implies x = 63\\\\\text{Hence, the number is 63.}[/tex]
Answer:
[tex]\huge\boxed{\bf\:x = 63}[/tex]
Step-by-step explanation:
Given,
4/7th of a number = 36Let's take the unknown number as 'x'.
Now,
4/7 × x = 36
Take the reciprocal of 4/7 to the other side of the equation .
x = 36 × 7/4
Cancel 36 by 4.
x = 9 × 7
Multiply the 2 numbers
