1a+18=7a
18=7a-1a
18=6a
6a=18
a=18/6
a=3

Subtract the 1a from the 7a.
1a + 18 = 7a
-1a -1a

you're then left with 18=6a. divide the 6 with the 18 to cancel out.
18=6a
/6a /6a

18 divided by 6 is 3. So your answer is a=3

15 points please help!! :) Find the value of x.

Answer:

Question 4: -11

Question 5: -7

Step-by-step explanation:

Four

Every triangle has 180 degrees.

So all three angles add to 180

Equation

60 + 80 + x + 51 = 180

Solution

Combine the like terms on the left. This is the first time I've seen x be a negative value. Almost all of the time it isn't, which should make you wonder.

191 + x = 180

Subtract 191 from both sides.

191 - 191 + x = 180 - 191

x = - 11

Five

If a triangle is a right triangle and one of the angles is 45, then so is the other one.

Proof

a + 45 + 90 = 180 Combine like terms on the left

a + 135 = 180 Subtract 135 on both sides.

a + 135-135=180-135 Combine the like terms

a = 45

Statement

That means 52 + x = 45 and here is another negative answer. Subtract 52 from both sides

52 - 52 + x = 45 - 52 Combine like terms.

x = - 7

Lin bought 1 pretzel from a snack cart that was marked $4.50. Why did she pay $4.83?

marshall27 [118]

Answer:

Sales tax

Step-by-step explanation:

You might have like 3% sales tax which is 3 percent of the original price added back onto it.

Sales tax is a tax that is put onto wanted and gourmet things, so chocolate isn't a needed item in life, so you have sales tax on it. On something like bread or meat, there might not be sales tax since you need food to survive. If something cost $100, and there is 3% sales tax, you will pay 103 dollars since 0.03 of 100 is 3.

TO TRANSMIT INFORMATION ON THE INTERNET, LARGE FILES ARE BROKEN INTO PACKETS OF SMALLER SIZES. EACH PACKET HAS 1,500 BYTES OF IN

stich3 [128]

Answer:

A. It would be needed 20 packets to transmit 30,000 bytes of information and B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

Step-by-step explanation:

1. Let's review the information provided to us for solving the question:

Size of each packet of information = 1,500 bytes

Number of packets = P

Number of bytes of information = B

2. Let's answer the questions:

A. How many packets would be needed to transmit 30,000 bytes of information?

P = 30,000 ÷ 1,500

P = 20

It would be needed 20 packets to transmit 30,000 bytes of information

B. How much information could be transmitted in 30,000 packets?

B = 30,000 * 1,500

B = 45'000,000

45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.
