X/4 + 5 = x/3 + 10

x/4 - x/3 = 10 - 5

(3x -4x)/12 = 5

-x/12 = 5

-x = 12 *5

-x = 60

x = -60.

Check:
Left Hand side, LHS:
x/4 + 5

-60/4 + 5 = -15 + 5 = 5- 15 = -10

Right Hand side, RHS:
x/3 + 10

-60/3 + 5 = -20 + 10 = 10- 20 = -10

-10 = -10
LHS = RHS

So,

$\frac{x}{4} +5= \frac{x}{3} +10$

To get rid of the fractions, find the LCM of the denominators.

LCM of 4, 3 = 12

Multiply both sides by 12.

3x +60= 4x +120

Subtract 3x from both sides.
60 = x + 120

Subtract 120 from both sides.
x = -60

Check.

$\frac{-60}{4} +5= \frac{-60}{3} +10$

-15 + 5 = -20 + 10

-10 = -10

This checks.

S = {-60}

I NEED HELP ASAP Find the area of this parallelogram.

Flura [38]

Answer:

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 15 and h = 5, thus

A = 15 × 5 = 75 cm² → B

Identify the type of function represented by... please help

Vladimir [108]

Answer:

Exponential decay.

Step-by-step explanation:

You can use a graphing utility to check this pretty quickly, but you can also look at the equation and get the answer. Since the function has a variable in the exponent, it definitely won't be a linear equation. Quadratic equations are ones of the form ax^2 + bx + c, and your function doesn't look like that, so already you've ruled out two answers.

From the start, since we have a variable in the exponent, we can recognize that it's exponential. Figuring out growth or decay is a little more complicated. Having a negative sign out front can flip the graph; having a negative sign in the exponent flips the graph, too. In your case, you have no negatives; just 2(1/2)^x. What you need to note here, and you could use a few test points to check, is that as x gets bigger, (1/2) will get smaller and smaller. Think about it. When x = 0, 2(1/2)^0 simplifies to just 2. When x = 1, 2(1/2)^1 simplifies to 1. Already, we can tell that this graph is declining, but if you want to make sure, try a really big value for x, like 100. 2(1/2)^100 is a value very very very veeery close to 0. Therefore, you can tell that as the exponent gets larger, the value of the function goes down and gets closer and closer to zero. This means that it can't be exponential growth. In the case of exponential growth, as the exponent gets bigger, your output should increase, too.

Donis bought a t-shirt for $15 and jeans for $35.50. If the sales tax rate is 8.25%. What is the sales tax for the t-shirt and j

SOVA2 [1]

<h3>Answer: 4 dollars and 17 cents</h3><h3>This is the same as saying $4.17</h3>

====================================================

Explanation:

15+35.50 = 50.50 dollars is the total before tax is applied.

Take 8.25% of this to get

0.0825*50.50 = 4.16625

and this rounds to 4.17, which is the amount of sales tax charged.

$4.17 = 4 dollars + 17 cents
