Answer:
x = 20
y = 12
Step-by-step explanation:
opposite angles are congruent so we can set up this equation:
5x + 29 = 7x - 11
29 = 2x - 11
40 = 2x
x = 20
5(20) + 29 = 129
7(20) - 11 = 129
3y + 15 = 5y - 9
15 = 2y - 9
24 = 2y
y = 12
3(12) + 15 = 51
5(12) - 9 = 51

Step-by-step explanation:
at a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of levi jeans with an original price of x?
Given:
Discount = 40%
Sales tax = 7%
To find:
The total cost of levi jeans with an original price of x.
Solution:
Let x be the original price of the jeans. Then the price after 40% discount is
[tex]Price=x-40\%\text{ of }x[/tex]
[tex]Price=x-\dfrac{40}{100}x[/tex]
[tex]Price=x-0.4x[/tex]
[tex]Price=0.6x[/tex]
The price after 7% of sales tax.
[tex]Price=0.6x+7\%\text{ of }0.6x[/tex]
[tex]Price=0.6x+\dfrac{7}{100}\times 0.6x[/tex]
[tex]Price=0.6x+0.042x[/tex]
[tex]Price=0.642x[/tex]
Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.

Given the inequality 6x - 10y ≥ 9 select all possible solutions!!
( -1, 1)
( 2, 8)
( 2, 1)
(-3, -4)
( 5, 2)
( 4, -2)
============================================================
Explanation:
The inequality 6x - 10y ≥ 9 solves to y ≤ (3/5)x - 9/10 when you isolate y.
Graph the line y = (3/5)x - 9/10 and make this a solid line. The boundary line is solid due to the "or equal to" as part of the inequality sign. We shade below the boundary line because of the "less than" after we isolated for y.
Now graph all of the points given as I've done so in the diagram below. The points in the blue shaded region, or on the boundary line, are part of the solution set. Those points are D, E and F.
We can verify this algebraically. For instance, if we weren't sure point E was a solution or not, we would plug the coordinates into the inequality to get...
6x - 10y ≥ 9
6(5) - 10(2) ≥ 9 .... plug in (x,y) = (5,2)
30 - 20 ≥ 9
10 ≥ 9 ... this is a true statement
Since we end up with a true statement, this verifies point E is one of the solutions. I'll let you check points D and F.
-----------
I'll show an example of something that doesn't work. Let's pick on point A.
We'll plug in (x,y) = (-1,1)
6x - 10y ≥ 9
6(-1) - 10(1) ≥ 9
-6 - 10 ≥ 9
-16 ≥ 9
The last inequality is false because -16 is smaller than 9. So this shows point A is not a solution. Choices B and C are non-solutions for similar reasons.
Write the equation of a line that is parallel to y = -5/4x+ + 7 and that passes through the point (-4,1).
Answer: y- 1 = -5/4(x+4)\\
Step-by-step explanation:
y = mx + b, where m is the slope, and in the equation, the slope is -5/4.
For two-line that are parallel, the slope is the same, -5/4.
[tex]y - y_{1}= m( x - x_{1})\\y- 1 = -5/4(x-(-4))\\y- 1 = -5/4(x+4)\\[/tex]

1. 10
2. 14.1421
3. 8
4. 6.9282
Step-by-step explanation:
To find 1, you need to use tangent. Let's say the missing side is x. You need to use tan(45) = x/10 to be able to solve. If you don't know how to do that, you just need to multiply by 10 on both sides, that way the 10 cancels out and all you get is x. Tan(45) multiplied by 10 is 10.
Now, find 2 with sine. The equation is sin(45) = 10/x. First, you need to multiply both sides by x so you get 10 alone. Now, divide both sides by sin(45) to cancel out the left side and get the answer to 2. 10/sin(45) = 14.1421 (I don't know if you need to round).
To find 3, you need to use cosine. The equation would be cos(60) = 4/x. Again, multiply both sides by x to get 4 alone. Next, divide both sides by cos(60). 4/cos(60) is 8.
To find 4, you need to use sine again. The equation is sin(60) = x/8. Multiply both sides by 8, and there's your answer. 6.9282.

Henry bought a pair of shoes that were on sale for 25% off. The sale price of the shoes was $42. What was the original price?
Answer:
$56
Step-by-step explanation:
Find out the percentage of the pair of shoes after the sale discount.
100 - 25 = 75%
75% = 42
1% = 42 ÷ 75 = 0.56
100% is the percentage of the original price.
100% = 0.56 x 100 = 56

Please assist me with this Distribution Problem
9514 1404 393
Answer:
1. 6.1 to 10.3
2. 9.6 hours
3. 7.5 hours
Step-by-step explanation:
1. The empirical rule or the supplied chart will tell you that μ ±3σ of the distribution is within 99.7% of the mean. Here, that is ...
8.2 ±3(0.7) = 8.2 ±2.1 = [6.1, 10.3]
The range of hours is 6.1 to 10.3 hours.
__
2. 2.5% of the distribution is above μ +2σ, or ...
8.2 +2(0.7) = 9.6 . . . hours
__
3. The bottom 16% of the distribution is below μ -σ, or ...
8.2 -0.7 = 7.5 . . . hours
