Four times a number plus three times a second number is negative nine. Twice the first number plus the second number is three

Given:

The statement is "the difference of 18 and 12".

To find:

The expression for the given statement.

Solution:

We have,

Given statement = The difference of 18 and 12.

We use subtraction, to find the different between two numbers and subtraction is represented by negative sign. So, we need to subtract second number form the first number.

The difference of 18 and 12 = 18 - 12

Therefore, the required expression for the given statement is 18-12.

Answer:

18. 20,000.

19. 0

7. 1

11. 101

Step-by-step explanation:

18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.

19. Sea level is at zero altitude. So answer is 0.

7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.

11. |-101| = 101. As said before the lines mean to make the inside part positive.

Answer:

5.28+2.4=7.68

is right answer

Answer:

Simplifying

27 + y = 10

Solving

27 + y = 10

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + y = 10 + -27

Combine like terms: 27 + -27 = 0

0 + y = 10 + -27

y = 10 + -27

Combine like terms: 10 + -27 = -17

y = -17

Simplifying

y = -17

Answer:

$19.03

Step-by-step explanation:

Okay, this is a standard percentage problem, so learning how to do this is necessary. First, we have to find what 6% of $17.95 is, since of is our keyword and that means to multiply, and percentages turn into decimals:

17.95 x 0.06 = 1.08

So we have our tax, then we have to add that to our original price to get the whole thing:

17.95 + 1.08 = 19.03

So the total sale price is $19.03

Answer:

1. Mode = 7

2. Range = 8

Step-by-step explanation:

The following set of data were obtained from the question:

4, 6, 5, 9, 3, 2, 7, 7, 1, 8

Mode =?

Range =?

1. Determination of the mode of the data.

Mode is simply defined as the mark (score) with the highest frequency. Thus we can obtain the mode as follow:

Scores >>>>>>> Frequency

4 >>>>>>>>>>>> 1

6 >>>>>>>>>>>> 1

5 >>>>>>>>>>>> 1

9 >>>>>>>>>>>> 1

3 >>>>>>>>>>>> 1

2 >>>>>>>>>>>> 1

7 >>>>>>>>>>>> 2

1 >>>>>>>>>>>> 1

8 >>>>>>>>>>>> 1

From the above illustration, we can see that the mark 7 has the highest frequency. Therefore, 7 is the mode of the data .

2. Determination of the range of the data.

Range of a given data is simply obtained by calculating the difference between the highest and the lowest score. The range can be obtained as follow:

Highest score = 9

Lowest score = 1

Range = Highest – Lowest

Range = 9 – 1

Range = 8

Answer:

$901.64

Step-by-step explanation:

Given data

rate= 7%

Final amount = $1650

time= 9 years

Let us apply the compound interest formula to solve for the Principal amount P

A=P(1+r)^t

substitute

1650=P(1+0.07)^9

1650=P(1.07)^9

1650=P1.84

Divide both sides by 1.84

P=1650/1.83

P=901.64

Hence she needs to invest $901.64

Answer:

$4200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 35000 × 0.02 × 6 = 4200

I = $ 4,200.00

The simple interest accumulated

on a principal of $ 35,000.00

at a rate of 2% per year

for 6 years is $ 4,200.00.

Answer:

I’m thinking $4200

Step-by-step explanation:

Because 35k at 2% for 6 years will get you that

Answer:

3 times 30 miles and 4 times 40 miles

Step-by-step explanation:

Travis will ride at a distance of 30 miles after 3 hours and at a distance of 40 miles after 4 hours.

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Given that,

Travis is planning to ride at a constant speed during an upcoming bike trip.

This implies that the slope of the graph will be a constant.

So the graph will be a straight line.

We have two points on the graph (1, 10) and (2, 20).

The starting point will be (0, 0).

Slope = (20 - 10) / (2 - 1) = 10

So the equation of the line is y = 10x.

When x = 3 hours, y = 30 miles

When x = 4 hours, y = 40 miles

Hence the points has to be marked at (3, 30) and (4, 40).

Step-by-step explanation:

negative numbers work backwards, in this case 8 is smaller then 5 as its farther in the numberline (if you were to draw one)

Answer:

Yes

Step-by-step explanation:

-5 is greater than -8 because -5 is closer to zero. You need to add 5 to get to 0 with -5, but 8 to get to 0 with -8.

Answer:

21u3

Step-by-step explanation:

Given that the volume of  a sphere is two-thirds the volume of a cylinder.

Let the volume of the sphere be A and that of the cylinder be B then

A = 2/3 B

Given that the volume of the sphere of same diameter as a cylinder is 14u3 then

14u3 = 2/3 B

Multiply both sides by 3

42u3 =2B

Divided both sides by 2

21u3 = B

The volume of the cylinder in terms of u3 is 21u3
