Answer:
x = 1
Step-by-step explanation:
Step 1: Write equation
-5(2x - 5) - 3x - 5 = 7
Step 2: Solve for <em>x</em>
- Distribute -5: -10x + 25 - 3x - 5 = 7
- Combine like terms: -13x + 20 = 7
- Subtract 20 on both sides: -13x = -13
- Divide both sides by -13: x = 1
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-5(2(1) - 5) - 3(1) - 5 = 7
-5(2 - 5) - 3 - 5 = 7
-5(-3) - 8 = 7
15 - 8 = 7
7 = 7
Answer:
m=21
Step-by-step explanation:
based on the dilation from 'ABC' to 'QRS' (which is 3) m should =21
hope this helps! :)
Answer:
$390
Step-by-step explanation:
so he has $500
he took $40,which is $460
then he put in $30,$490
then he took away $100,$390
hopefully you understand
Cosine = adjacent / hypotenuse
So that means the adjacent side = 15 and the hypotenuse = 17
By Pythagorean Theorem, we know that
opposite^2 = hypotenuse^2 - adjacent^2
opposite^2 = 17^2 - 15^2
opposite^2 = 289 - 225
opposite^2 = 64
opposite side = 8
sine = opposite / hypotenuse
So,
sine A = 8 / 17
