What does this mean?

Answer:

52a² - 39a

Step-by-step explanation:

Step 1: Write out expression

3a(4a - 5) - 4a(6 - 10a)

Step 2: Distribute

12a² - 15a - 24a + 40a²

Step 3: Combine like terms (a²)

52a² - 15a - 24a

Step 4: Combine like terms (a)

52a² - 39a

Answer:

Angle DAC and EAB are the same. (Shared Angle)

Angle AEB and ADC are the same. (Corresponding Angle)

Angle EBA and DCA are the same. (Corresponding Angle)

Since all three angles of triangle ABE is the same as triangle ACD, they are similar.

Answer:

40 degrees

Step-by-step explanation:

Hi, so basically angles AOB and BOC added together equal angle measure AOC. First, we have to substitute the values in.

108=(3z+4)+(8z-28)

Then, combine like terms

108=11z-24

Add 24 to both sides

132=11z

Divide both sides by 11

12=z

So now all we need to do to find measure AOB is substitute 12 for z in the given equation (AOB=3z+4)

AOB=3(12)+4

AOB=36+4

AOB=40

Answer:

Step-by-step explanation:

We’ve all been there. You know how it goes… you’re out with your friends, you order an inexpensive item on the menu to be your frugal/responsible self, and then the bill comes and someone says, “Let’s just split it equally! That’ll make it easy!” Then, out come the wallets, credit cards, and cash. It’s awkward to pipe up and say, “Uh, but, uh, I only had the $7 thing not the $35 thing, and no wine or dessert or appetizers!”

No one what’s to be the cheap/poor/miser in the group. I’ve been there. Trust me. It’s not a fun place to be. So, how do you deal?

Lucky for us, a reader wrote in with that very question:

“This weekend I went out to a friend’s birthday dinner which was out at a restaurant. We’d recently gone out to eat for this friends’ sisters birthday and everyone in the group paid for themselves. Additionally, during all the other previous times we went out, that I can remember, we all pay for ourselves.

Well this weekend, when the bill came, one of the guests at the table suggested that we all split the bill 6 ways to make things simpler and so that the birthday girl wouldn’t have to pay. This was devastating to me and my wallet! I’d looked at the menu before getting to the restaurant and chose one of the cheapest entrees, which was $15.75. With tax and tip I figured my bill would be no more than about $20. I even brought about that amount of cash. The final bill was $300. Split six ways and its $50!!! I sucked it up and paid $50 because I was too embarrassed to say anything, particularly since I only really knew the birthday girl, her husband and her sister. Any advice on what to do in those situations or what to do before the bill comes to avoid those types of situations?”

Erm. Completely awkward, right.

$1.75 more each person would have to pay if the $7.00 was added to the bill for a dessert that everyone shared.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

If each person paid $6.75.

The total is 27$. 27 divided by 6.75 is 4. Suppose

$7.00 was added to the bill for a dessert that everyone shared.

Let x be the amount that each friend needs to share.

Addtional amount = $7.00

Number of people 4

Each people need to pay = 7/4 = $1.75

Thus, $1.75 more each person would have to pay if the $7.00 was added to the bill for a dessert that everyone shared.

Answer:

[tex]\huge\boxed{\frac{2}{15} \text{ yards}}[/tex]

Step-by-step explanation:

We have a board that is [tex]\frac{2}{3}[/tex] yards long. If we want to cut the board into 5 equal pieces, we must divide [tex]\frac{2}{3}[/tex]  by 5.

[tex]\frac{2}{3} \div 5[/tex]

5 is the same thing as [tex]\frac{5}{1}[/tex], so:

[tex]\frac{2}{3} \div \frac{5}{1}[/tex]

To divide a fraction by a fraction, we multiply by the reciprocal. This means we take the reciprocal of [tex]\frac{5}{1}[/tex] and multiply the two fractions.

The reciprocal of [tex]\frac{5}{1}[/tex]  is [tex]\frac{1}{5}[/tex] - we swap the numerator and denominator.

[tex]\frac{2}{3} \cdot \frac{1}{5}[/tex]

Multiply the numerator and denominators to get our final fraction:

[tex]2\cdot 1 = 2\\3 \cdot 5 = 15\\\\\frac{2}{15}[/tex]

Answer:

4/9

Step-by-step explanation:

The only other recurring decimal would be 4/3 but that's greater than 1.

Answer:

4/9

Step-by-step explanation:

1/2 is 0.5

4/3 doesn't matter. It's an improper fraction, so it's above 1.

9/10 is 0.9

So, the only one left is 4/9, which is 0.44 repeating.

Answer:

x=3/2y+3

Step-by-step explanation:

Let's solve for x.

2x−3y=6

Step 1: Add 3y to both sides.

2x−3y+3y=6+3y

2x=3y+6

Step 2: Divide both sides by 2.

2x2=3y+62

x=32y+3

Answer:

y = 3

Step-by-step explanation:

First, subtract 8 on both sides (because we have to get the variable alone):

-5y = -15

Then, divide -5 on both sides (simplify):

y = 3
