A vendor sells hotdogs and bags of potato chips .A customer buys 4 hot dogs and 4 bags of chips for $17.00 another customer buys
mario62 [17]
Let use h= hotdogs price and c=chips price
we know that
4h +4c= 17
5h+3c=17.75
t use the elimination method we will multiply the first equation by 5 and the second one by (-4)
20h +20c=85
-20h -12c= -71
8c=14, we will divide by 8 both side and c=1.75, so a bag of potato chips cost $ 1.75
now we will substitute the c in the first equation
4h+7=17     therefore  4h=17-7,    4h=10,     h=2.50

a bag of potato chips is 1.75
a hot dog costs 2.50

Hello!

You have to do 7 * 2/5

Which is the same as 7/1 * 2/5

Which gives us the answer 2 4/5 bottles of glue.

Hope this helps!

Answer:

C.

x y

2 -24

5 -15

Step-by-step explanation:

We need to find the slope for each table

A.

x y

2 16

5 10

m = (y2-y1)/(x2-x1) = (10-16)/(5-2) = -6/3 = -2

B.

x y

2 14

6 12

m = (y2-y1)/(x2-x1) = (12-14)/(6-2) = -2/4 = -1/2

C.

x y

2 -24

5 -15

m = (y2-y1)/(x2-x1) = (-15--24)/(5-2) = (-15+24)/3 = 3

D.

x y

2 -12

6 -16

m = (y2-y1)/(x2-x1) = (-12--16)/(6-2) = (-12+16)/4 = 1

E.

x y

2 -19

6 -17

m = (y2-y1)/(x2-x1) = (-17--19)/(6-2) = (-17+19)/4 = 1

The greatest unit rate is the largest slope

I need help i under stand the adding version just not subtraction
zavuch27 [327]
---------------------------------
Define x and y :
---------------------------------
Let x be the number of large boxes.
Let y be the number of smaller boxes.

---------------------------------
Construct equations :
---------------------------------
x + y = 125 -------------------------- (1)
50x  + 30y = 4850 ---------------- (2)

---------------------------------
From equation (1) : 
---------------------------------
x + y = 125
x = 125 - y

---------------------------------
Substitute x = 125 - y into (2) :
---------------------------------
50 (125 - y) + 30y = 4850
6250 - 50y + 30y = 4850
20y = 1400
y = 1400 ÷ 20
y = 70

---------------------------------
Sub y = 70 into equation 1
---------------------------------
x + y = 125
x + 70 = 125
x = 55

---------------------------------
Find the number of boxes :
---------------------------------
Large box = x = 55
Small box = y = 70

---------------------------------------------------------------------------------------------------
Answer: There are 55 large boxes and 70 small boxes.
---------------------------------------------------------------------------------------------------
