Alia buys a computer. The original price of the
computer is $379.99. She uses a coupon for 15%
off any item. She must pay 6.75% sales tax on the
sale price. How much money will Alia spend on the
computer? (Hint....tax goes on the sales price!)
Answer:
$344.79
Step-by-step explanation:
379.99 decrease 15% =
379.99 × (1 - 15%) = 379.99 × (1 - 0.15) = 322.9915
322.9915 increase 6.75% =
322.9915 × (1 + 6.75%) = 322.9915 × (1 + 0.0675) = 344.79342625

Annika saving money for a trip. She's able to save $75 a week. Her friend from Iceland Eva is also saving money. Eva is able to save 9000 Kronas (Icelandic money) each week. If $4 is equal to 509 Kronas, who is saving at a greater rate?
please show your work/steps
Answer:
Annika is saving more money than Eva
Step-by-step explanation:
first I divide 9000 by 509 and got 17.68 then I multiplied that by 4 and got 70.72 so that is what eva makes a week in us dollars

3 dozens = _______ units
Answer:
36 unit
Step-by-step explanation:
1 dozen= 12 units
3 dozen = 12 × 3 = 36 units
1. All of the variables below are directly proportional, write an equation linking them:
a. V= 12 when M =4
b. T= 5 when S=1
c. Y= 34 when x=2
d. H=48 when M=4
e. P= 5 when N=10
Answer:
a. V = 3M
b. T = 5S
c. Y = 17x
d. H = 12M
e. P = 0.5N
Step-by-step explanation:
a. V= 12 when M =4
12/4 = 3, so in this case, V is 3 times M, that is, V = 3M
b. T= 5 when S=1
5/1 = 5, so in this case, T is 5 times S, that is, T = 5S
c. Y= 34 when x=2
34/2 = 17, so in this case, Y is 17 times x, that is, Y = 17x
d. H=48 when M=4
48/4 = 12, so in this case, H is 12 times M, that is, H = 12M
e. P= 5 when N=10
5/10 = 1/2 = 0.5, so in this case, P is half of N, that is, P = 0.5N

Formulate a step-by-step explanation (in words) on how to simplify (x^2+2x-8)/(x^2+7x+12). Be sure to write a sentence for each step (use correct mathematical language). Which step did you find most difficult to explain and why?
Answer:
see attached
Step-by-step explanation:
kindly go through the work i have done. ask for any clarification
Answer:
(x - 2) / (x + 3)
Step-by-step explanation:
We proceed to factor both polynomials:
x^2+2x-8 = (x + 4) * (x - 2) in numerator
x^2+7x+12 = (x + 4) * (x + 3) in denominator
therefore, there is a common factor (x + 4) which can be cancelled in the original rational expression, resulting in the following rational expression:
(x^2+2x-8)/(x^2+7x+12) = (x - 2) / (x + 3)
All steps where pretty simple.

Solve the system of equations using substitution.
y = -7x
2x - y = -9
Step-by-step explanation:
Since y= -7x you will want to substitute the y in the other equation.
2x -(-7x) = -9
2x + 7x = -9
9x = -9
so x will be -1
y= -7(-1)
x= -1
y= 7
Answer:
x = -1 , y =7 (-1,7)
Step-by-step explanation:
[tex]y=-7x\\2x-y = -9\\[/tex]
[tex]2x+7x = -9[/tex]
[tex]2x+7x = 9x\\[/tex]
[tex]9x = -9\\[/tex]
[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]
[tex]x = -1\\[/tex]

Step-by-step explanation:
-5х + Зу = -8
3х - 7y = -3
Answer:
wrong
Step-by-step explanation:
-5x + 3y, you can’t add those together since they aren’t like numbers
3x - 7y, can’t be done either since again, they aren’t like numbers.
like numbers include the same variable or no variable, which means you cant do -5x + 3y but you can to -5x + 3x. you can add those together since both of the numbers have the variable “x” while 3y and 7y have the same variable “y” therefore those can be added together.
since there isn’t a way to add those, both of those answers are not only wrong, but they’re also in simplest form.
Which statement is true about comparing 5.37 and 5.4?
5.4 is greater because 43

5.4 is greater because it has fewer digits.
5.37 is greater because it has more digits.
PLSSSSSS HELP!!!! TIME LIMITEDDD!!!!!! Joan wants to draw a picture that includes a pair of complementary angles. Joan wants one of the angles to be 18° more than the other angle. Select True or False for each statement about the angles.
The smaller angle is 18°.
The smaller angle is 36°.
The larger angle is 54°.
The larger angle is 72°.
Answer:
True: The smaller angle is 36°; The larger angle is 54°
False: The smaller angle is 18°. The larger angle is 72°
If you create an equation using this scenario, it would be (18+x)+x=90, because complementary angles sum up to 90°. Add the like terms to get 18+2x=90. Subtract 18 on both sides to get 72. Divide 2 on both sides to result with x=36. Subtract 90 with 36 to get 54. The smaller angle is 36° and the larger angle is 54°.

One morning, the temperature outside was -3°F. By 5:00PM the temperature had decreased 15°F. What was the temperature at 5:00 PM?
a. -18°F b. -12°F C. 12°F d. 18°F
Answer:
A.
Step-by-step explanation:
If the temperature was -3°F at first, but had decreased 15°F degrees by 5:00pm, it would be -18°F.
-3 - 15 = -18
Correct me if I end up being wrong.
the scale on a map is 1:25000. how many km on the ground is represented by 6cm on the map?
Given:
The scale on a map is 1:25000.
To find:
How many km on the ground is represented by 6cm on the map?
Solution:
Let x be the km on the ground.
We know that,
1 km = 1000 m
1 m = 100 cm
So,
1 km = 100,000 cm
x km = 100,000x cm
The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.
[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]
[tex]\dfrac{100,000x}{25000}=6[/tex]
[tex]4x=6[/tex]
[tex]x=\dfrac{6}{4}[/tex]
[tex]x=1.5[/tex]
Therefore, 1.5 km on the ground is represented by 6cm on the map.

9/18 = 0.5
If you write the problem out x will represent the missing number
9 ÷ x = 18
You can write it as 9 ÷ 18
which is 0.5
