Answer and Step-by-step explanation:
The interior angles of a triangle a add up to 180. We can find x by subtracting everything from 180, and then divide for x.
180 = x + 4 + 68 + x
<u>Simplify.</u>
180 = 2x + 72
<u>Subtract 72 from both sides of the equation.</u>
108 = 2x
<u>Divide each side by 2.</u>
x = 54
<u>The angles of the triangle are:</u>
Angle S = 54
Angle U = 58
Angle T = 68

Answer:
21 to 28
Step-by-step explanation:
15:20
Divide each side by 5
15/5 : 20/5
3:4
we want to find the one that is 3:4
5 to 10 Divide by 5 5/5 to 10/5 1 to 2
18:25 this does not simplify
21 to 28 divide by 7 21/7 to 28/7 3 to 4
24:30 divide by 6 24/6: 30/6 4:5
Answer:
$27.14
Step-by-step explanation:
Price of 1 DVD: $9.10
Price of 4 DVDs: 4 * $9.10 = $36.40
Discount: 25%
Now we find 25% of $36.40.
25% of $36.40 =
= 0.25 * $36.40
= $9.10
The 25% discount amounts to $9.10. We now subtract $9.10 from $36.40 to find the discounted price.
$36.40 - $9.10 = $27.30
Now we need to apply the 6.75% tax to $27.30.
6.75% of $27.30 =
= 0.0675 * $27.30
= $1.84
The sales tax is $1.84.
Now we add the sales tax amount to the total discounted price.
$27.30 + $1.84 = $29.14
Answer: $27.14
If you would like to solve the system of linear equations, you can do this using the following steps:
2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x
The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
