Answer:
Step-by-step explanation:
We need to create an equation to represent how many air fresheners the teacher can buy.
Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.
x = number of air fresheners
($10 + $3) / $3.50 = x can be written as $13/$3.50 = x
We add $10 and $3 because that gives us the total amount she has to spend.
We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.
In this case.
$13/$3.50 = x
3.71 = x BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.
Answer:
x=15 and y=18
Step-by-step explanation:
1: 2/3x- 4=6 2/3x=10 x=15
1: x=15
2: 2/3y=12
y=18
Answer:
sqrt(29)
Step-by-step explanation:
To find the distance between two points, we use the formula
d = sqrt( ( x2-x1)^2 + (y2-y1)^2 )
d= sqrt( ( 8-6) ^2 + ( 2-7)^2)
= sqrt ( 2^2 + (-5)^2)
= sqrt 4+25)
= sqrt (29)
She would have 60 altogether. she would need 3 yogurt packages and 5 juice packages.
