Answer:

y=12

Step-by-step explanation:

Use order of operations. Subtract 18 from both sides and the divide by 2.

2y+18 -18=42-18

2y=24

y=12

Because of the commutative property of multiplication 3/4X4=4X3/4 However these expressions can be calculated in different ways

elena55 [62]

Answer:

We obtain same product by both the methods.

Step-by-step explanation:

We are given the following in the question:

Commutative property of multiplication:

$\dfrac{3}{4}\times 4 =4\times \dfrac{3}{4}$

Different ways to find the product:

1. First way

$\dfrac{3}{4}\times 4\\\\=3\times \dfrac{4}{4}\\\\=3$

2. Second way

$\dfrac{3}{4}\times 4\\\\=\dfrac{12}{4}\\\\=3$

We get the same product for both the calculations.

Use long division to divide x^3+x^2-2x+14 by x+3

bekas [8.4K]

First, $x^3=x^2\cdot x$ , and if we multiply $x+3$ by $x^2$ we get

$x^3+3x^2$

Subtracting this from the numerator gives a remainder of

$-2x^2-2x+14$

Next, $-2x^2=-2x\cdot x$ , and if we multiply $x+3$ by $-2x$ we have

$-2x^2-6x$

and subtracting this from the previous remainder, we end up with a new remainder of

$4x+14$

Next, $4x=4\cdot x$ , and if we multiply $x+3$ by $4$ we get

$4x+12$

Subtracting from the previous remainder, we get a new remainder of

$2$

which contains no more factors of $x$ , so we're done.

So,

$\dfrac{x^3+x^2-2x+14}{x+3}=x^2-2x+4+\dfrac2{x+3}$

40% of the groups budget was spent on activities. If $64,000 was spent on the activities, what was the full budget? solve with t

Andre45 [30]

Answer:

The full budget has a total value of $160,000

Step-by-step explanation:

This is a simple ratio problem and can be solved using the Rule of Three property. The Rule of Three is used to compare two ratios and find the missing part. In this case the ratios would be the following.

$\frac{64,000}{40 percent} = \frac{x}{100 percent}$

$\frac{64,000 * 100 percent}{40 percent} = \frac{x}$

$\frac{6,400,000}{40 percent} = \frac{x}$

$160,000= \frac{x}$

So now we know that 100% (The full budget) has a total value of $160,000.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
