Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 before tax was added. What was the cost of each sweat?
Answer:
$35
Step-by-step explanation:
first we need to find the amount of money the sweaters cost alone.
so we first subtract the total (160) - the skirt price (20) which is 140
now we divide it by 4 to find the price of each seater, as they all cost the same.
so 140 divided by 4 = 35
answer: $35
Which situation can be represented by the equation 4d + 5 = 29?
Answer:
d=6
Step-by-step explanation:

Calculate the vertices of the figure given by A (1, 3), B (4, 7), and C(6, 6) after being
translated using the rule (x, y) > (x + 2, y + 3).
The new points are:
A’
B’
C’
Answer:
see explanation
Step-by-step explanation:
The rule (x, y ) → (x + 2, y + 3 )
Means add 2 to the original x- coordinate and add 3 to the original y- coordinate, that is
A (1, 3 ) → A' (1 + 2, 3 + 3 ) → A' (3, 6 )
B (4, 7 ) → B' (4 + 2, 7 + 3 ) → B' (6, 10 )
C (6, 6 ) → C' (6 + 2, 6 + 3 ) → C' (8, 9 )

Is line p || to line q? Why?
Step-by-step explanation:
yes, because the angles match. per rule of intersecting lines the angles in one side of an intersected line are the same but mirrored on the other side of the line.
since q behave exactly as p would regarding the intersecting angles, they are parallel.

Solve for x. Show each step of the solution.
2.5(4-x)+12=21-4(2.5x+7)
Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86

Two numbers multiply to be 20 and add to be 12. What are the numbers?
Answer:2 and 10
Step-by-step explanation:
Write the equation of the line in fully simplified slope/intercept form
Answer:
y = m x + b standard form for straight line
m = (y2 - y1) / (x2 - x1)
When y2 = 12, x = -6
when y = 0, x = -2
m = (12 - 0) / (-6 - (-2)) = -3
so y = -3 x + b
Also, when x = 0, y = -6
Our equation is
y = -3 x - 6
As a check try x = -2
y = (-3 * -2) + (-6) = 0 as the graph shows

Answer:
] The three consecutive even numbers are 38, 40 and 42. The smallest of the three is clearly 38. Step-by-step explanation:Even numbers are of the form [math]2k[/math], [math] k \in \mathbb{Z}[/math]. Three consecutive even numbers are of the form [math]2k[/math], [math]2(k+1)[/math], [math]2(k+2)[/math]. We have that their sum is 120 therefore [math]\\2k + 2(k+1) + 2(k+2) = 120 \Leftrightarrow k+(k+1)+(k+2) = 60 \Leftrightarrow 3(k+1) = 60 \\ \Leftrightarrow k+1=20 \Leftrightarrow \boxed{k=19}.[/math
let h(x) be the inverse of f(x).If h(x)=-4+1 find f(x)
Assuming you meant to type h(x)=-4x+1
Answer:
[tex]f(x)=-\frac{1}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
We know that, because [tex]h(x)[/tex] is the inverse of [tex]f(x)[/tex], that [tex]h(f(x))=x[/tex], so [tex]-4f(x)+1=x[/tex].
Aha! We can solve for [tex]f(x)[/tex]!
We subtract [tex]1[/tex] from both sides to get [tex]-4f(x)=x-1[/tex].
Finally, we divide both sides by [tex]-4[/tex] to get [tex]\boxed{f(x)=-\frac{1}{4}x+\frac{1}{4}}[/tex].
Jeff wants to buy tickets for a football game for his friends. The stadium is selling tickets for $7 each. The stadium requires a

{28, 42, 56, 70, 84}
Your answer is D){28, 42, 56, 70, 84}
To answer this question you just have to make sure the amount he pays is a multiple of 7.If you know you times table then this should be easy
Times table of 7:
7,14,21,28,35,42,49,55,63,70,77,84.
Now you just need to find an answer choice who has these numbers.Lets check it out!
A) 11 isn't a multiple of 7
B) 56 isn't a multiple of 7
C) None of these are multiples of 7 except 7 so this is also incorrect
D) This is correct because they are all multiples of 7
Hope this makes sense.

f(0)= 2(0+2)+ 4(0)= 4
f(16)= 2(16+2)+ 4(16) = 100
f( 10) = 2(10+2) + 4(10)= 64
f(94)= 2( 94+ 2) + 4(94) = 568

What expression would give you a product of 16
Answer:
12+4 is the expression that will give you a sum of 16
4•4 is an expression that will give you a product of 16
remember an expression does not have an equal sign if it had an equal sign then it would be an equation and expression has no equal sign

Chloe paid $21.18 for a large pizza including tax and delivery fees. She gave the delivery person
$25 and told the delivery person to keep the change. Did she give the delivery person a 20% tip?
Explain.
Answer:
No, she tipped about 18%.
Step-by-step explanation:
How much she tipped:
$25 - $21.18 = $3.82
To find the percentage, you can put this tip over the what she paid for the pizza.
[tex]\frac{3.82}{21.18} =0.18=18%[/tex]%
She only tipped about 18%

given f(x)=-x-1 find (6)
Answer:
[tex]{ \rm{f(x) = - x - 1}} \\ \\{ \rm{f(6) = - 6 - 1}} \\ \\ { \rm{f(6) = - 7}}[/tex]
Answer:
f(6) = -7
Step-by-step explanation:
It is given that x = 6. Plug in 6 for x in the given equation:
f(x) = -x - 1
f(6) = -(6) - 1
Note that when you are subtracting two negative numbers, you are really adding the two numbers:
f(6) = -(6) - 1
f(6) = -7
When x = 6, f(x) = -7
