Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?
Answer:
$84
Step-by-step explanation:
so for store A, you would do $17*12 smoke detectors, Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The amount less spend by buying in store A than in store B is $84
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The number of smoke detectors to be purchased.
= 12
Store A:
Cost of one smoke detector = $17
Cost of 12 smoke detectors.
= 12 x 17
= $204
Store B:
Cost of one smoke detector = $24
Cost of 12 smoke detectors.
= 12 x 24
= $288
Now,
The difference between the cost of 12 smoke detectors from store A to store B.
= $288 - $204
= $84
Thus,
The amount less spend by buying in store A than in store B is $84

Find the slope of the line passing through each of the following pairs of points.
(0, -8), (0,4)
Answer:
The slope is undefined
Step-by-step explanation:
You can find the slope by doing change in y/change in x.
Y changed by 12 units while x changed by 0.
12/0 is undefined, so the slope is as well (on a graph, the line would be vertical)
0 or undefined or infinity
Step by step explanation:
slope = y2 - y1 / x2 - x1
= 4 + 8 / 0 + 0
= 12 / 0
= 0

Can someone please give me the answers thank u !!!
Answer:
D.
Step-by-step explanation:
I have been doing this in Geometry.
We know perpendicular means opposite recipicoles and opposite slopes.
so.. the slope is 3 to get the y-intercept you do this.
(1, 2) Use the points it gave you and the slope 3 and put it is y=mx + b form
2 = 3(1) + b (I do this because I don't know what b is yet) (b = y-intercept)
2 = 3 + b (subtract 3 on both sides)
-1 = b
The equation is y = 3x - 1

How many unit cubes are required to create a larger cube with edge length of 3 units? Can I also get an explanation so I know how it's done? Thanks :)
Answer:
The unit cubes that are required to create a larger cube with an edge length of 3 units is:
27 cubes.Step-by-step explanation:
To identify the number of cubes you need to create a larger cube, you must think in the number of cubes of the length (3 cubes in this case), and use the exponent 3, because you need to form a cube. Below I'll show you:
[tex]3^{3}= 27 cubes.[/tex]To understand it in a better form, suppose that you need a cube with an edge of 5 units, in that case, remember you use the number 5 how base and the exponent is 3, because is a cube, in that case, it would be:
[tex]5^{3}= 125 cubes[/tex]If it wasn't a cube but a square, you must elevate to the number 2, in the case of the cube is elevated to 3, so, the unit cubes that are required to create a larger cube with an edge length of 3 units is 27 cubes.

i took the test
is 6.1 or 6.18 bigger and how you know which one is larger.
Answer:
6.18 is larger
Step-by-step explanation:
Written with an equivalent number of decimal places, we are comparing ...
6.10
6.18
__
Use these rules for comparison of positive numbers:
1. If the left-most non-zero digits are in number places with different place values, the one with the digit in the highest place value is larger.
2. If the left-most non-zero digits are in number places with the same place value, the number with the larger digit is larger.
3. If the left-most non-zero digits are in the same number place and have the same value, replace those digits with 0, and repeat the comparison starting with the first test above. If one of the numbers has no more non-zero digits, use zero. If both of the numbers have no more digits, they are equal--neither is larger.
__
Following the above rules, we compare the units digits to find they are the same.
Then we compare the tenths digits, and find they are the same.
Then we compare the hundredths digit of 6.18 to 0 to find that 8 > 0, so 6.18 > 6.1
_____
Alternatively (for numbers of any sign), subtract one number from the other. If the result is positive, the minuend is larger. If the result is negative, the subtrahend is larger. If the result is zero. the numbers are equal.

-7-2x=7(x+8)
What is the answer for this expression
Answer:
x=-7
Step-by-step explanation:
1. Distribute the 7 into the parenthesis: -7-2x=7x+56
2. Combine like terms by doing the opposite operation to the numbers: -7=9x+56 (added 2x to 7x)
3. Subtract 56 to each side of the equation: -63=9x
4. To isolate the variable "x," divide each side by 9: x=-7
