Answer:

h = -4

Step-by-step explanation:

Step 1: Distribute

-3h - 15 + 2 = 4h + 24 - 9

Step 2: Isolate x's

-15 + 2 = 3h + 4h + 24 - 9

-15 + 2 -24 + 9 = 3h + 4h

Step 3: Combine like terms

-28 = 7h

Step 4: Divide both sides by 7

h = -4

Alternatively, you can guess and check by plugging in each solution into the calc and seeing if it is correct or not.

Jack collected 1350 pounds of waste paper for recycling today. If he decided to collect 24% more pounds of waste paper tomorrow,

miv72 [106K]

324 pounds

24% = $\frac{24}{100}$ = 0.24

0.24 × 1350 = 324 pounds

He should collect 324 more pounds of waste paper

2(3/5x+3). How would I get that answer

Airida [17]

Answer: $\frac{6}{5}$ x + 6

Step-by-step explanation:

We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.

Given:

2(3/5x+3)

Distribute:

2 * (3/5x) + (2 * 3)

6/5x + 6

Answer:

$\frac{6}{5}$ x + 6

Find the distance between the points with polar coordinates (3, 120°) and (0.5, 49°)

nikklg [1K]

X 1 = 3 * cos 120° = - 3 cos 60° = - 3/2 = - 1.5
y 1 = 3 * sin 120° = 3 sin 60° = 3√3 / 2 = 2.598
x 2 = 0.5 * cos 49° = 0.328
y 2 = 0.5 * sin 49° = 0.37735479
--------------------------------------------
d = [( x 2 - x 1 )² + ( y 2 - y 1 )²]^(1/2)
d = [ ( 0.328 + 1.5 )² + ( 0.37735479 - 2.598) ] ^(1/2)
d = ( 3.341584 +4.931265 )^(1/2)
Answer: The distance is :
d = 2.876256
