You are selling hot dogs and sodas. Each hot dog costs $1.50 and each soda costs $0.50. At the end of the night, you made a total of $78.50. You sold 87 hot dogs and sodas altogether. You must report to your manager the number of hot dogs and sodas that were sold. How many hot dogs and how many sodas were sold?

Answers

Answer 1

Answer:

x= hot dogs

y= soda

Total sold

1 x + 1 y = 87 .............1

2 x 0.50 y = 78.50 .............2

Eliminate y

multiply (1)by -0.50

Multiply (2) by 1.00

-0.50 x -0.50 y = -43.50

2 x + 0.50 y = 78.50

Add the two equations

1 x = 35.00

/ 1

x = 35.00

plug value of x in (1)

1 x + 1 y = 87

35 + y = 87

y = 87 -35

y = 52

y = 52.00

x= 35 hot dogs

y= 52 soda

Even though the 7 is in () it's being multiplied by 3 is exponent would still come first

3(49) + 81

147 + 81 = 228

Answer:

228

Step-by-step explanation:Take 7 and multiply it by itself. you get 49. times 49 by 3 you get 147. Take 9 and multiply it by itself. You get 81. 147 plus 81 = 228

Answers

Answer: A) 2/3

Method: Here’s an easy method for questions like these, when you are looking at a triangle, look at the angle that’s away from the biggest line (if it’s a right triangle choose any angle), for this case angle W. Now count how many lines it takes to get to the big line, for the original triangle it’s 6 and for the new triangle it’s 4. Now since you have your numbers turn it into a fraction (new on top original on bottom), 4/6. Finally see what the answer is, for this case 4/6 is equal to 2/3, so there’s your answer.

Required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]

What is slope ?

The slope of a line is a measure of the steepness and direction of the line. Finding the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or missing without using a compass.

The slope of any straight line can be calculated using two points on the line. The slope of the line formula calculates the ratio of "vertical change" to "horizontal change" between two different points on the line. In this article we will understand the slope finding method and its applications.

The slope of a line is defined as the change in the y-coordinate relative to the change in the x-coordinate of that line. The net change in the y-coordinate is Δy, while the net change in the x-coordinate is Δx. Thus, the change in the y-coordinate with respect to the change in the x-coordinate can be written as: m = Δy/Δx

Here given,Equation of line [tex] \frac{5}{3}y = - (x - 5)[/tex]

We want to find what is 5/3y=-(x-5) in slope intercept form ?

We want to simplify the equation.

[tex]5y = - 3(x - 5) \\ 5y = - 3x + 15 \\ y = \frac{ - 3x + 15}{5} \\ y = - \frac{3}{5} x + \frac{15}{5} \\ y = - \frac{3}{5} x + 3....(1)[/tex]

We know slope in line y = mx+c is m.

We are comparing equation (1) with y = mx + c and get [tex]m = - \frac{3}{5} [/tex]

Equation (1) is slope intercept form of 5/3y=-(x-5).

Therefore,required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]
