Answer:
k =3
Step-by-step explanation:
2/5(5k+35) -8 =12
Add 8 to each side
2/5(5k+35) -8+8 =12+8
2/5(5k+35) =20
Multiply each side by 5/2
5/2 *2/5(5k+35) =20*5/2
5k+35 = 50
Subtract 35 from each side
5k+35-35 = 50-35
5k = 15
Divide by 5
5k/5 = 15/5
k =3

Simplify 1/4 + 1.20 explain
Answer:
1/4 +1 1/10_.25 + 1.20
Step-by-step explanation:
1/4 also known as a quarter, should easily be known as .25, and .20 should be equal to 1/10 since .20x10 equals 1. that one in the equation doesn't really make a difference. (it's kinda just there¯\_(ツ)_/¯) so technically you have your answer.

Jamaal is using a photo-editing computer program. He sets up the "F1" key to perform a 20% enlargement in both dimensions. He sets up the "F2" key to increase the picture size by 2cm in both dimensions. Then Jamaal sets up "F3" to do "F1" followed by "F2".
What is the equivalent function for a picture xcm by xcm?
A f3(x)=f2(f1(x))=1.2x+2
B f2 (x)+(fx+f1) (x)=2.2x=2
C f3 (x)=f1(f2(x))=1.2x+2.4
D f3 (x) = (f2 *f1)(x)=1.2x^2+2.4x
Answer:
A f3(x)=f2(f1(x))=1.2x+2
Step-by-step explanation:
The "F1" key is to perform a 20% enlargement in both dimensions. So, first the function F1 increases the dimension x by 20%. That is, our new dimension x' is now the initial dimension plus the increase. The initial dimension is x and the increase is 20% of x = 0.2x. So, x' = x + 0.2x = 1.2x. So, F1(x) = x' = 1.2x
Then, the "F2" key is to increase the picture size by 2cm in both dimensions. So, the function F2 works on x' and add 2 cm to it. So, our new dimension is thus x" = x' + 2.
So F2(x') = x" = x' + 2 = F1(x) + 2
F2(F1(x)) = x' + 2 = 1.2x + 2
F3(x) = F2(F1(x)) = 1.2x + 2
F3(x) = 1.2x + 2.
So, the equivalent function for a picture x cm by x cm is F3(x) = F2(F1(x)) = 1.2x + 2.
It cost Aaron $6.72 to send 168 text messages. What is the cost of sending text messages, in dollars per text?
Answer:
$4
Step-by-step explanation:
If you remove the decimal from the cost and divide it by the number of text messages you get how much each individual message costs. (672 \ 168 = 4)

m = [tex]\frac{y-b}{x}[/tex]
Step-by-step explanation:
Given
y = mx + b ( subtract b from both sides )
y - b = mx ( isolate m by dividing both sides by x )
[tex]\frac{y-b}{x}[/tex] = m

Step-by-step explanation:.
The Huggins family went out to dinner. The price of the meal was $62.95. The sales tax is 8% of the
price of the meal. The tip is 15% of the meal and the sales tax. How much money did the family
pay for the meal, including tax and tip?
Answer:
$62.95 (meal) + $5.03 (sales tax) +$.75 (sales tax tip) + $9.44 (meal tip)
Total: $78.17
Answer:
$78.19
Step-by-step explanation:
To find the total after the sales tax is charged you have to do
$62.95 x 1.08 (1 = to the total and .08 to add sales tax value) =$67.986 round*
Now you take $67.99 (has been rounded) and multiply but .15 to find out what is 15% of $67.99 , it comes out to be 10.1979 (Round)
Now to finish you add $67.99 +$10.20 = $78.19

Answer:
$250
Step-by-step explanation:
If they are making 100 burritos, you multiply $1.50 and 100 to get $150, and then $1.00 and 100 to get $100. Add $150 and $100 together to get $250, that is how much it cost to make the burritos. If they sold all 100 burritos, they would gain a profit of $550.
if 22,x,y,31 are in ap. find the values of x and y
Answer:
x = 25, y = 28
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 22 and
a₄ = a₁ + 3d = 31 , that is
22 + 3d = 31 ( subtract 22 from both sides )
3d = 9 ( divide both sides by 3 )
d = 3
Thus
x = 22 + 3 = 25
y = 25 + 3 = 28

Step-by-step explanation:
José and Maris work for different car dealerships. José earns a monthly salary of $3,500 plus a 8% commission on sales. Maris earns a monthly salary of $3,900 plus a 6% commission on sales. Above what value of sales are José's monthly earnings more than those of Maris?
Answer: When sales are greater than 2000 then José's monthly earnings sre more than those of Maris.
Step-by-step explanation:
Let x= Total sales
For José, monthly salary = $3,500
Commission percentage = 8% =0.08
Monthly earnings= Monthly salary + (Commission percentage) x (Total sales)
Monthly earnings= 3500 +0.08 x
For Maris, monthly salary = $3,900
Commission percentage = 6%
Monthly earnings= 3900 +0.06 x
When José's monthly earnings > Maris's monthly earnings
then, 3500 +0.08 x > 3900 +0.06 x
Subtract 3500 from both sides, we get
0.08 x > 400+0.06x
Subtract 0.06x from both sides, we get
0.02x>400
Divide both sides b 0.02
x> 20000
When sales are greater than 2000 then José's monthly earnings sre more than those of Maris.

Select all the true statements. Group of answer choices The ratio of triangles to squares is 2 to 4. The ratio of squares to smiley faces is 6:4. The ratio of smiley faces to triangles is 6 to 4. There are two squares for every triangle. There are two triangles for every smiley face. There are three smiley faces for every triangle.
Answer:
The ratio of triangles to squares is 2 to 4
There are two squares for every triangle.
There are three smiley faces for every triangle.
Step-by-step explanation:
The number of triangles, smiley and squares are shown in the diagram attached.
From the diagram, there are 6 smiley faces, 2 triangles and 4 squares.
A ratio compare two or more values, thereby showing how many times one number contains the other.
A) Correct. The ratio of triangles to squares = number of triangle / number of square = 2 / 4 = 2 to 4
B) Incorrect. The ratio of squares to smiley faces = number of square / number of smiley face = 4 / 6 = 4 to 6
C) Incorrect. The ratio of smiley faces to triangles = number of smiley faces / number of triangles = 6 / 2 = 6 to 2
D) Correct. Since the ratio of squares to triangles = number of squares / number of triangle = 4 / 2 = 2 / 1 = 2 to 1, hence there are two squares for every triangle
E) Incorrect. Since the ratio of triangles to smiley faces = number of triangle / number of smiley faces = 2 / 6 = 1 / 3 = 1 to 3, hence there is one triangle for every 3 smiley faces
F) Correct. Since the ratio of smiley faces to triangles = number of smiley faces / number of triangles = 6 / 2 = 3 / 1 = 3 to 1, hence there is 3 smiley faces for every one triangle
