The two numbers are 53/6 and -55/6.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Let x and y be the two numbers.

We have sum of them is -1/3

x + y = -1/3  [Equation 1]

The difference of two numbers is 18.

x - y = 18   [Equation 2]

x + y + x - y = -1/3 + 18

2x = 18 -

2x = 53/3

x = 53/6

Substituting the value in equation 1,

53/6 + y = -1/3

y = -1/3 - 53/6

= -55/6

Hence the numbers are 53/6 and -55/6.

y + 7 = - 2/5 * (x - 10) . What is theThe point-slope of the equation of the line that passes through (- 5, - 1) and (10, - 7) is standard form of the equation for this line? 2x - 5y = - 15 2x - 5y = - 17 2x + 5y = - 15 2x + 5y = - 17

The Standard Form of the Equation is A. 2x - 5y = -15

Step-by-step explanation:

Given points: (-5, -1) and (10, -7).

Find the slope:

m = (y - y1)/(x - x1)

= -1 - (-7)/-5 - 10

= -1 + 7/-15

= 6/-15

m = -2/5

y - y1 = m(x - x1)

y - (-7) = -2/5(x - 10)

y + 7 = -2/5(x - 10)

The rest of the question is looking for the standard form of the equation:

Ax + By = C

Begin by solving the point slope form for y:

y + 7 = -2/5x + 20/5

y + 7 = -2/5x + 4

y = -2/5x - 3

Now, put the equation into the standard form:

y + 2/5x = -3

Multiply by 5, and place x first:

2x + 5y = -15, the Standard form of the Equation

Prove by setting x = 0 and finding the y intercept:

5y + 2(0) = -15

5y = -15

y = -3, giving the y intercept, when x = 0 as -3 or (0, -3)

4. A restaurant bill for a group of people comes to a total of \$125. This amount
included an 8% sales tax and a 20% tip, both based on the price of the food.
Which equation could be used to find f, the cost of the food?
Ar 125 = 0.28f
Br 125 = 1.08f +0.20
C.) 125 = f +0.28
D., 125 = 1.28f

The answer is D). 125 = 1.28f. This accounts for both sales tax and the cost of food.

Mary Stevens earns \$6 an hour at her job and is entitled to time-and-a-half for overtime and double time on holidays. Last week she worked 40 hours of regular time, 61/2 hours of overtime, and 8 hours of holiday time. How much did she earn? A. \$140.00 B. \$394.50 C. \$190.75 D. \$74.37

She earned \$394.50

Step-by-step explanation:

1. Hourly income of Mary Stevens in regular hours = \$6
2. Hourly income of Mary Stevens in over-time =
3. Hourly income of Mary Stevens in holidays =

Then, last week she worked

1. 40 hours of regular time, earnings =
2. hours of overtime, earnings =
3. 8 hours of holiday time, earnings =

Hence, her total earnings = 240+58.5+96 = \$394.50

6 X 40 for regular time = 240

and then if you add in the overtime and holiday time the answer will be more than 240 and the only answer above 240 is B

An airplane on autopilot took 5 hour to travel 3,475 kilometers what was the airplane speed in kilometers per hour

the speed of the aeroplane is 695 km/h.

Step-by-step explanation:

Distance traveled=3475 km

Time taken = 5 hours

Speed of airplane= Distance / Time

= 3475/5= 695 km/h

HEnce the speed of the aeroplane is 695 km/h.
