Answer:
Step-by-step explanation:
You are finding out each time how much is the items Zachary bought.
Then inputting a equation
$1,600 - ??? = $1,370
To find the unknown number, you must subtract the 2 original numbers.
$1,600 - $1,370 = $230
Computer costs: $230 leaving Zachary with $1,370 left.
Next, it says he purchased another computer...
$1,370 - ??? = $1,140
Again, we subtract the 2 original numbers to find the unknown.
$1,370 - $1,140 = $230 leaving Zachary with $1,140 left.
Now we input this data into an equation...
y = -230x + 1600.

Answer: A, C, A, B
Step-by-step explanation:
For all of these, we can use indecy laws such as when there is a power of a power, you can multiply the powers.
Using this, we get 6^-3 x -1 or,
6^3
For the second one we get (6)^-3 x 3 or,
6^ of negative 9 which is neither.
I am guessing that the last 2 are fractions. (1/6)^-3 is equal to 216 which is 6^3.
For the last one, (1/6)^3 is basically the opposite so the answer is 6^-3.
Hope this helps!

what is -0.75 - 0.4 simplified
Answer:
= -0.75-0.4
= -1.15
Step By Step
The simplified result of -0.75 - 0.4 is -1.15.
To simplify the expression -0.75 - 0.4
Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.
Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.
Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.
Putting it all together, we have -0 - 0.35 = -0.35.
But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.
In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.
So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).
In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.

Jim's lawn is a rectangle that is 15 5/6 yards long and 10 2/5 yards wide. Jim buys sod in pieces that are 1 1/3 yards long and 1 1/3 yards wide. How many pieces of sod will Jim need to buy and cover his lawn?
Answer:
Its 93
length of Jim's backyard , L = 15 5/6 = 95/6 yards
width of Jim's backyard , B = 10 2/5 = 52/5 yards
so, area of rectangular backyard = L × B
= 95/6 × 52/5
= (95 × 52)/30
= 494/3 yard²
Jim buys sod of length 1 1/3 = 4/3 yards and width = 1 1/3 yards = 4/3 yards .
so, area of rectangular sod = length × width
= 4/3 × 4/3 = 16/9 yard²
number of sod = area of backyard or area of sod
= (494/3)/(16/9)
= 494 × 3/16
= 92.625 ≈ 93
therefor, 93 pieces of sod will Jim need to buy to cover his backyard.

When you learned to add decimals, you saw that lining up the decimal point in the addends is really important. Why do you think it is not necessary to line up the decimal points in the two factors when multiplying decimals?
Answer in 2 complete sentences.
Answer:
It is not necessary to line up decimals while multiplying because you count the decimals instead of bringing them down. Plus lining up decimals while adding can overcomplicate the problem with too many zeros.

3 liters of water are shared equally by 5 people how much water does each person get? division equation to represent the situation
600 mililiters each
Step-by-step explanation:
1 liter is equal to 1000 mililiter and is multiplied by 3 and the answer is devided into 5.
The division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.
What is division?The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.
Now it is given that,
Number of People = 5
Liters of water = 3
So, Water shared by each person = Liters of water / Number of People
⇒ Water shared by each person = 3/5
This is the division equation to represent the situation.
⇒ Water shared by each person = 0.6
Thus, the division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.
