5x+2y=24 and 8x+2y=30

Mathematics
1 answer:
larisa86 [58]3 years ago
3 0

Answer:

x = 2

y = 7

Step-by-step explanation:

5x+2y=24  -------------->equ 1

8x+2y=30 -----------> equ 2

equ 1 - equ 2 =====>         -3x = - 6

                                               x = -6 / -3  = 2

                                               x = 2

Put x = 2 in equ 1,  

 5*2 + 2y = 24

10 + 2y = 24

        2y = 24 - 10

         2y = 14

            y = 14/2

            y = 7

horrorfan [7]
The description for slope is the rise over run. In other words, this is the ratio of the vertical displacement to the horizontal displacement. In equation form, that would be:

Slope = Δy/Δx = (14000 - 12000)/(3000 ft)
Slope = 2/3

<em>So, the answer is C.</em>

zubka84 [21]

Answer:

$5.99 for 1.5 lbs of gumballs

Step-by-step explanation:

You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.

3.99 / 2 = 1.995

Then add the price of 1 pound

3.99 + 1.995 = 5.985

Then you can round that up to 5.99
