Answer:
$22.78
Step-by-step explanation:
Cost Price: 20.98
Tax is 8.6% of this: 20.98 x 0.086 = 1.80
Total price = Cost Price + Tax:
Total = 20.98 + 1.80 = $22.78

Find the LCM of 40a2b and 48ab4.
Answer:
Step-by-step explanation:
40a²b = 2* 2 * 2 * 5 * a² * b = 2³ * 5 * a² * b
48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴ = 2⁴ * 3 * a * b⁴
LCM = 2⁴ * 3 * 5 * a² * b⁴
= 16 * 3 * 5 * a² * b⁴
= 240a²b⁴

If 3x – 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y?
Answer: x=4, y=-1
Step-by-step explanation:
Multiply the second equation by 3:
18x+9y=63
Then summarize both equations 18x+9y+3x-9y=21+63
21x=84 => x=4
use x=4 in any of initial equations ,for instance in first one:
3*4-9*y=21
12-9*y=21
9y=12-21
9y=-9
y=-1

Answer:
gidetgfddtgfft5f5f5f5d5f6guhuhug5xtdrd4s4d5d6v7g7h8n8b7v6v6
Answer:
Let J represent the number of tickets Jose sells. Let M represent the number of tickets Mark sells. Make equations, if Mark sells 15 more tickets than Jose, the equation is J+15=M. Because we know that in between both of them they sell 63 raffle tickets, then M+J=63. Now plug in the value of M (J+15) into M+J=63. And you get (J+15)+J=63, which is 2J+15=63. Subtract 15 from both sides and get 2J=48. Now divide 48 by 2, J=24. So now you know Jose sold 24 tickets, and to find how many Mark sold, plug in 24 into J+15=M and get 24+15=M where M is 39. Now check, 24+39=63. So Mark sold 39 tickets and Jose sold 24.

which of the following shows the solution to the inequality
Answer:
I got x = 1
Step-by-step explanation:
First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:
[tex]1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1[/tex]
And since -2.5 is less than -1 this statement is true. x does in fact equal 1

Explain how you know. Is the point (20,24) on line ℓ? Explain how you know. Is the point (80,100) on line ℓ? Explain how you know.
Answer/Step-by-step explanation:
First find the equation of the line. The graph is a proportional graph. Hence, the equation would be in the form is y = kx.
Where k I stye constant of proportionality (y/x).
Using a point on the line, (4, 5),
k = y/x = ⁵/4
Substitute ⁵/4 into y = kx.
Thus, the equation of the graph would be:
y = ⁵/4x
Plug in the value of the x and y coordinates of a point into the equation to determine if the point is on line l. If it makes the equation true, then it is a point on the line.
Thus:
✍️For the point, (20, 24), substitute x = 20, y = 24 in y = ⁵/4x
24 = ⁵/4(20)
24 = 5(5)
24 = 25 (NOT TRUE)
✅Therefore, the point, (20, 24) is not a point on line l.
✍️For the point, (80, 100), substitute x = 80, y = 100 in y = ⁵/4x
100 = ⁵/4(80)
100 = 5(20)
100 = 100 (TRUE)
✅Therefore, the point, (80, 100) IS A POINT on line l.

Help me pleasee (10 points)
Answer:
B
Step-by-step explanation:
Givens
a^2 + b^2 = c^2
a = 4x
b = x + 2
c = 3x + 4
Solution
(4x)^2 + (x + 2)^2 = (3x + 4)^3 Remove all the brackets.
16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16 Collect like terms on the left
17x^2 + 4x + 4 = 9x^2 + 24x + 16 Subtract the terms on the right
8x^2 - 20x - 12 = 0
This factors into
(4x - 12)(2x + 1)
There are 2 answers
4x - 12 = 0
4x = 12
x = 12/4
x = 3
or
2x + 1 = 0
2x = - 1
x = - 1/2
You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.
So the only answer is x = 3
