ParenthesesExponentsMultiplication ⇄ DivisionAddition ⇄ SubtractionWe can evaluate 7 + 2 × 4 - 8 - 4.
Start with multiplication:
7 + (2 × 4) - 8 - 47 + 8 - 8 - 4Now we can add and subtract from left to right.
15 - 8 - 47 - 4 3The answer to this problem is 3.
Answer:
Step-by-step explanation:
here because its an expression you use bodmas then you take 7+2= 9 take 9 times 4 = 36 take 36 minus 8 = 28 take 28 minus 4 = 24 this is the answer
if f(x) is an even function, which function must also be even?
1) f(x-2)
2) f(x)+3
3) f(x+1)
4) f(x+1)+3
Answer:
Step-by-step explanation:
Option 2 is correct.
if function is even , it is symmetrical about y axis.
if this function shift horizontally it will not remain symmetrical about y axis
if this function shift vertically it will remain symmetrical about y axis

Answer:
1) The discount is $4.05
The sale price is $18.45
2) The discount is $10
The sale price is $30
3) The discount is $2.6
The sale price is $23.4
Step-by-step explanation:
1) What is the discount and sale price for a haircut that originally cost $22.50 with an 18% discount.
Actual Price= $22.50
Discount = 18%
Finding discount:
[tex]18\%\:of\:22.50\\=\frac{18}{100}\times 22.50\\=4.05[/tex]
So, the discount is $4.05
Finding Sale Price
The sale price can be found by: [tex]Sale\;Price=Actual\:Price-Discount[/tex]
Putting values and finding sale price:
[tex]Sale\:Price=22.50-4.05\\Sale\:Price=18.45[/tex]
The sale price is $18.45
2) What is the discount and sale price for a sweatshirt that originally priced $40.00 with an 25% discount.
Actual Price= $40.00
Discount = 25%
Finding discount:
[tex]25\%\:of\:40.00\\=\frac{25}{100}\times 40.00\\=10[/tex]
So, the discount is $10
Finding Sale Price
The sale price can be found by: [tex]Sale\;Price=Actual\:Price-Discount[/tex]
Putting values and finding sale price:
[tex]Sale\:Price=40.00-10\\Sale\:Price=30[/tex]
The sale price is $30
2) What is the discount and sale price for a large pizza that originally cost $26.00 with an 10% discount.
Actual Price= $26.00
Discount = 10%
Finding discount:
[tex]10\%\:of\:26.00\\=\frac{10}{100}\times 26.00\\=2.6[/tex]
So, the discount is $2.6
Finding Sale Price
The sale price can be found by: [tex]Sale\;Price=Actual\:Price-Discount[/tex]
Putting values and finding sale price:
[tex]Sale\:Price=26.00-2.6\\Sale\:Price=23.4[/tex]
The sale price is $23.4

Answer: Non-proportional
Step-by-step explanation:
The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70
So...you know that it is not proportional
The variables Y and X have a proportional relationship andY equals 15 when x=3. What is the value of X when Y =4?
Answer:
4/5 or 0.8
Step-by-step explanation:
y and x is directly proportional so when one increases the other also increases
the scale factor is 15/3 equals 5
so y is 4, x times 5 equals 4, which we rearrange to give 4/5 or 0.8

If the sales tax rate is 8%, how much tax would Luis pay for a pair of pants for $18 and two shirts for $9.99 each?
Answer:
$3.04 (rounded to nearest cent)
Step-by-step explanation:
Total cost without tax = $18 + $9.99 × 2
= $37.98
Tax = [tex]\frac{8}{100}[/tex] × $37.98
= $3.04 (rounded to nearest cent)

divide 4/20=5
5x4=20
The constant is 5
Answer:
B. 5
Step-by-step explanation:
1/k = 4/20 (Given)
1/k = 1/5 (Reduce)
1 = 1/5k (Multiply k on both sides)
5 = k (Divide 1/5 on both sides)

Find the value of x and y with the steps PLEASE.
Answer:
x=70
y= 40
Step-by-step explanation:
the triangle containing x is an isosceles triangle so two of the sides are 55.
55+55+x=180.
110+x=180
110-110+x=180-110
x=70
Triangle BAC is equilateral so 180/3=60. Now
x+60+c=180
70+60+c=180
130+c=180
130-130+c=180-130
c=50
That gives us one corner of triangle CBD. We know a second angle is 90 so
50+90+y=180
140+y=180
140-140+y=180-140
y=40
I think that is correct but you are free to check it yourself

The altitude to the hypotenuse of a right triangle divides the hypotenuse into segments whose lengths are in the ratio of 1:4. The length of the altitude is 12. How long is the hypotenuse?
9514 1404 393
Answer:
30
Step-by-step explanation:
The altitude is the geometric mean of the two segments of the hypotenuse. For some scale factor x, the segments are 1x and 4x, and the altitude is ...
12 = √((1x)(4x)) = 2x
6 = x
So, the length of the hypotenuse is ...
(1x) +(4x) = 5x = 5·6 = 30
The hypotenuse is 30 units long.

Gabrielle saves $48 of her monthly paycheck for college.
She earned $120 last month. What percentage of her paycheck
did Gabrielle save? Choices:
20%
40%
35%
70%
(If you answer correctly, you will get 15 and I can answer one of ur questions. ONLY if you get it right)
The percentage of Gabrielle paycheck is 40%. Therefore, option B is the correct answer.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Gabrielle saves $48 of her monthly paycheck for college. She earned $120 last month.
Percentage of paycheck is
48/120 ×100
= 0.4×100
= 40%
Therefore, option B is the correct answer.

The scale factor from the large triangle to the small triangle is 3:1 What is the length of side x of the smaller triangle?
Answer:
10 i guess
cause
8*3=24
3*10=30
Step-by-step explanation:
Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)
Therefore 3x = 30 and x = 10.
Please tell me how to do it
Answer:
3 sqrt(13)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + 9^2 = c^2
36+81 = c^2
117 = c^2
Take the square root of each side
sqrt(117) = sqrt(c^2)
sqrt( 9*13) = c
sqrt(9) sqrt(13) =c
3 sqrt(13) =c
Willie and anjali each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Willie spent $116 on 12 daylilies and 4 pots of ivy. Anjali spent $60 on 6 daylilies and 3 pots of ivy. Find the cost of one daylily and the cost of one pot of ivy
Answer:the cost of one day lily = $9 and cost of one pot of ivy = $2
Step-by-step explanation:
Step 1
let day lilies be rep as d
and ivy be represented as i
So that The expression for what Willie spent on 12 day lilies and 4 pots of ivy = $116 be
12 d+ 4i = 116 ---- equation 1
and for Anjali spending $60 on 6 day lilies and 3 pots of ivy be
6d+ 3i = $60------ equation 2
Step 2 --- Solving
12 d+ 4i = 116 ---- equation 1
6d+ 3i = $60------ equation 2
Multiply equation 2 by (2) and subtracting equation 1 from it
12d+ 6i= 120
--12 d+ 4i = 116
2 i= 4
i = 4/2 = 2
TO find d, putting the value of i = 2 in equation 1 and solving
12d+ 4(2) = 116
12d= 116-8
12d= 108
d= 108/12= 9
Therefore the cost of one day lily = $9 and cost of one pot of ivy = $2
if a desktop computer costs $800 and a tablet costs $400, how can someone determine how many of each they can buy with $20000?
Answer:
it depends how many of each you want, you would take $800 for the price of the item or $400. then x for the amount of items you need. then put that all over your total and divide.

12.5 :) or 12 1/2
Answer: 12.5 sq units
Step-by-step explanation:
Make two triangles (big and small triangle) and one rectangle. ( kinda like what's in the pic)
Area of big triangle:
b = 3 h = 3
1/2 x 3 x 3 = 4.5 sq units
Area of small triangle:
b = 2 h = 2
1/2 x 2 x 2 = 2 sq units
Area of rectangle:
l = 3 w = 2
3 x 2 = 6 sq units
Area of the figure: A. of rect. + A. of s. tri. + A. b. tri.
6 + 2 + 4.5 = 12.5 sq units
