Step-by-step explanation:

$- 10n + 24 + 30n = - 36$

Collect like terms and simplify

[tex] -10n+30n=-36-24 \\ 20n = -60 [/tex]

Divide both sides of the equation by 20

[tex] 20n/20 = -60/20 \\ n=-3 [/tex]

Answer:

N=-3

Step-by-step explanation:

First step is to combine like terms. So combine -10n and 30n. Then you should have 20n+24=-36. Next step is to subtract 24 from both sides. So then you should have 20n=-60. Last step is to divide by 20 on both sides and you should get the answer

Answer:

Part 1: Angle = 36°

Part 2: Angle = 72°

Step-by-step explanation:

If we have an angle "x", then

Its complement is 90 - x, and

supplement is 180 - x

Let's write equations and solve.

Part 1:

Complement = 1.5 times angle

90 - x = 1.5x

90 = 1.5x + x

90 = 2.5 x

x = 90/2.5 = 36

Part 2:

Now using 2nd equation:

3 * angle = 2 * Supplement

3x = 2 (180 - x)

3x = 360 - 2x

3x + 2x = 360

5x = 360

x = 360/5 = 72

PLEASE HELP!!! here are two different strategies to find the new price of a hat after a discount of 40%. The hat was originally

Yakvenalex [24]

Answer:

Step-by-step explanation:

Method 1: Calculate 40% discount on original price, then subtract discount from original price.

Amount of discount = 40% of $30

= 0.40 × $30

= $12

New price = $30 - $12 = $18

Method 2:

New price = (100% - discount percentage) of original price

= 60% of original price

= 0.60 × $30

= $18
