5apples and 3 oranges cost $3.50 and 4 apples and 5 oranges cost $4.10. how much does one apple and one orange cost. let x = the cost of one apple. let y = the cost of one orange. a. write an equation for the cost of 5 apples plus 3 oranges. b. write an equation for the cost of 4 apples plus 5 oranges. c. solve the above system of equations using multiplication. d. what is the cost of one apple? what is the cost of one orange?

x= cost of apple and y= cost of orange:

5x+3y=3.50, 4x+5y=4.10.

So 20x+12y=14, so 20x=14-12y; 20x+25y=20.50.

Substitute for 20x in the second equation: 14-12y+25y=20.50

13y=6.50, y=0.50. But 5x=3.50-3y, so 5x=3.50-1.50=2.00 and x=0.40.

so the cost of one apple is 40 cents and one orange is frickiin 50

Step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
