Answer:

9,157 divided by 32=286.15625

9,157 rounded is 9.000

32 rounded is 30

9,000 divided by 30 equals the quotient of 300

our original answer 286, would round up to 300

Answer:

Step-by-step explanation:

We can use signed numbers to represent the position of an object along a line. We pick a point to be the reference point, and call it zero. Positions to the right of zero are positive. Positions to the left of zero are negative.

When we combine speed with direction indicated by the sign of the number, it is called velocity. For example, if you are moving 5 meters per second to the right, then your velocity is +5 meters per second. If you are moving 5 meters per second to the left, then your velocity is -5 meters per second.

If you start at zero and move 5 meters per second for 10 seconds, you will be  5⋅10=50  meters to the right of zero. In other words,  5⋅10=50 .

If you start at zero and move -5 meters per second for 10 seconds, you will be  5⋅10=50  meters to the left of zero. In other words,

−5⋅10=−50

In general, a negative number times a positive number is a negative number.

Answer:

x= 4

Step-by-step explanation:

[tex]-3x-4=-16\\\\-(-3x-4)=-(-16)\\\\-(-3x)-(-4)=16\\\\3x+4=16\\\\3x=16-4\\\\3x=12\\\\\frac{1}{3}(3x)=\frac{1}{3}(12)\\\\x=4[/tex]

Answer:

3x = 12

Step-by-step explanation:

-3x -4 = -16

     +4 = +4

-3x + 0 = -12

       -3x = -12

     -3x/- = -12/-

         3x = 12

For question 4.a), I think you meant x + 3 = 12.

4.a) x + 3 = 12

         - 3    -3

           x = 9

b.) 2x + 3 = 20

         - 3     -3

    2x = 17

     2     2

            x = 8.5

c.) -4x = -24

     -4      -4

    x = 6

d.) 2(x-4) = 10

    2x - 4 = 10

         + 4   +4

    2x = 14

     2     2

      x = 7

e.) -0.5x + 1.1 = -3.9

              - 1.1    -1.1

    -0.5x = -5

    -0.5     -0.5

         x = 10

Answer:

  opposite sides have the same slope, so it is a parallelogram

Step-by-step explanation:

A parallelogram has opposite sides that are parallel. Here, one pair of opposite sides consists of horizontal lines. Both have zero slope, so are parallel.

The other pair of lines each has a "rise" of 3 units for each "run" of 2 units, so the lines have a slope of 3/2. Both lines have the same slope, so are parallel.

Since opposite sides are parallel, the figure is a parallelogram.

Answer:

True

Step-by-step explanation:

Here, we want to check if the given equation does not intersect the x-axis

if it does not, then it has no real root

If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis

The formula for the discriminant is;

D = b^2-4ac

In the question;

a = -1 , b = 6 , c = 10

so;

D = 6^2-4(-1)(10)

D = 36-40

D = -4

Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis

8.

may 3rd -> july 15th = 73 days

500*0.06 = 30

30 = how much he makes in one day (so he has 530 after 1 day)

30*73 = 2190

500 + 2190 = 2690

9.

210/7 = 30

1% for 3 years = 30

1% for 1 year = 10

100% for 1 year = 1000

2000*0.06 = 120

11.

54,000*0.08 = 4320

54,000/4320 = 12.5

Step-by-step explanation:

Answer:

all correct

Step-by-step explanation:

Answer:

What you got right:

0.5 - Possible

48 - Possible

-6 - Not possible

0 - Not possible

BUT....

3 is possible

Step-by-step explanation:

When we want to know the side lengths of a rectangle and we have possible choices, we want to look at if it's in the realm of possibility. That is, if it's physically possible. You have 5/6 correct, so I think you've done a good job so far. But what you got wrong was the statement that 3 is not possible.

3 is possible, because 24 is divisible by 3. The length would then be 8. So, what you should have put is that 3 is Possible.

(my comment on someone else's answer is incorrect, you only got one wrong, my bad)

Answer:

j=38

Step-by-step explanation:

j/-2 +7=-12,  subtract 7 from both sides of the equation and you get j/-2 = -19, then you multiply j/-2 by -2/1  and multiply -19 by -2/1 to get j= 38

Answer:

Using the estimate:

The car has to go for 1,200 miles but it consumes a gallon of gasoline for every 30 miles. The number of gallons it will need is therefore:

= 1,200 / 30

= 40 gallons

Each gallon costs $3.00 so the total cost is:

= 40 * 3

= $120

Without using the estimate:

The car has to go for 1,211 miles but it consumes a gallon of gasoline for every 29 miles. The number of gallons it will need is therefore:

= 1,211 / 29

= 41.76 gallons

Each gallon costs $3.40 so the total cost is:

= 41.76 * 3.40

= $‭141.98

Using the estimate provides a lower cost of gasoline for the trip.
