Step-by-step explanation:

_16=_8x_4

4×_16=_8x 4×4

64=8x

divide both by 8

x=8

Answer 2

I got 1.5 = x. Do -16 = -8x -4 then you add the -4 to the -16 making it -12 = -8x the. You divide -8 to both sides and you will get 1.5 = X

Answers

Answer:

90 miles.

Step-by-step explanation:

Knowing that an inch is equal to 40 miles you can take 40 and multiply it by 2 1/4, thus getting 90. Or, you can break it down. 2 times 40 equals 80. This leaves 1/4 inch left to figure out. If you divide 40 by 4 (figuring out a fourth) you would get 10. Add 80 and 10 and you would have 90 miles.

Answer:

I think it will be 90

Answers

Answer:

a) s1 is 4 km/h because it is given. t1 is 30 min. s2 is 8 km/h. d is 4 km because given

b) d2 is 2 km because he travels 30 min at 4 km/h which is 2 km

c) d2 is 2 km because he travels 30 min at 4 km/h which is 2 km and 4 km-2 km is 2 km

d) 2 km at 8 km/hour is 1/4 hour which is 15 minutes so t2 is 15 min.

e) 3:45+15 min is 4:00

Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

or
3.14 x 7 x 7 x 4
A- 124.6
B- 87.9
C- 97.5
D- 78.9

Answers

Answer:

I think its A

Step-by-step explanation:

I did the math and thats what i got even rounded up

The value of the expression 3.14 x 4 x 4 x 7 is 351.4 and for expression 3.14 x 7 x 7 x 4 is 615.4.

To round the expression to the nearest tenth, we need to evaluate it first. Let's calculate each expression:

3.14 x 4 x 4 x 7 = 351.36

3.14 x 7 x 7 x 4 = 615.44

Now, let's round each result to the nearest tenth:

Rounding 351.36 to the nearest tenth gives us 351.4

Rounding 615.44 to the nearest tenth gives us 615.4

Based on the given options, neither result matches exactly.

However, option A (124.6) is the closest rounded value to 351.4.

Answers

Answer:

x=9

Step-by-step explanation:

expand 2(x+5) : 2x+10

2x+10=3x+1

subtract 10 from both sides

2x+10-10=3x+1-10

simplify

2x=3x-9

subtract 3x from both sides

2x-3x=3x-9-3x

simplify

-x=-9

divide both sides by -1 (-1 is equal to -x or -1x)

-x/-1=-9/-1

simplify

x=9

Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which line from the text most clearly explains the main idea of the first paragraph?Group of answer choices:Have you ever witnessed something amazing, shocking or surprisingHuman memories are really a mixture of many non-factual thingsHer brain may recall that the person was tall, but not be able to say how tallDocumented cases have shown eyewitnesses adding detail to testimony Fourteen school festival tickets were sold to adults and children.
