X= price of hotdog
y= price of hamburger
Set up equations for each stand. Multiply number of hotdogs and hamburgers sold by their prices (x and y) and add together to equal the total sold at each stand.
FIRST CONCESSION STAND
164x + 74y= $706
SECOND CONCESSION STAND
256x + 61y= $884
STEP 1
to solve by elimination, multiply first concession stand equation by 61; this will eliminate the y term
164x + 74y= $706
(61)(164x) + (61)(74y)= (61)(706)
10,004x + 4,514y= 43,066
STEP 2
multiply second concession stand equation by -74
256x + 61y= $884
(-74)(256x) + (-74)(61y)= (-74)($884)
-18,944x - 4,514y= -65,416
STEP 3
add step 1 & 2 equations together to solve for x
10,004x + 4,514y= 43,066
-18,944x - 4,514y= -65,416
y terms "cancel out"
-8,940x= -22,350
divide both sides by -8,940
x= $2.50 hotdog
ANSWER: $2.50 is the price of a hotdog.
Hope this helps! :)
Brian traveled 3 hours and annie traved 17 hours because 3 times 5 is 15 plus 2 is 17 and 17 plus 3 is 20 hours
Step-by-step explanation:
1. 1/9 of 450
of is multiply
1/9 × 450
= ???
2. 15/60 = decimal number
change number to percentage = ???
I dont know what 3 is
put answers to 1 and 2 in comments i will mark if u don't understand comment
please mark brainiest
Find value of determinant.
The determinant is a term that is inside a square root and part of the quadratic formula used for solving quadratic equations.
Let determinant be 'd'.
If d >0, Then there are 2 real solutions
If d = 0, Then there is only 1 real solutions
If d < 0, Then there are 0 real solutions but 2 imaginary solutions
d = b^2 - 4ac
For this problem, the coefficients are:
a = 1, b = -3, c = 8
d = (-3)^2 - 4(1)(8)
d = 9 -32 = -23
d is less than 0, therefore there are 0 real solutions and 2 imaginary solutions.
This is true because you cannot take square root of a negative number.
Answer:
= 1.75
Step-by-step explanation:
7/6 divided by 6
= 7/36
7/36 = x/9
Cross multiply fractions:
36x = 63
Divide each side by 36:
x = 7/4 or 1.75
