Answer:
More Than
Step-by-step explanation:
According to the given statement:
This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.
The two words in this problem which tell us about the operation are "More Than"
This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.
Since, x represents the earnings of last year, we can represent the earnings of this year as:
Twice of x + 20
2x + 20
1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
These must be - 48 and -46 Answer
Answer:
Total charge per month = $ 16 + (0.08) * x
equation for having same charge
0.08 x - 0.12 y = 8
Step-by-step explanation:
Part 1:
Monthly fee = $ 16
Per check fee = $ 0.08
Checks signed in month = x
Total Charge monthly = Monthly fee + Checks fee
Putting the values
Total charge per month = 16 + (0.08) * x ...........(i)
Part 2: Let she signs y checks for account B
Monthly fee of B = $ 14
per check fee = @ 0.12
Total Charge = monthly fee + checks fee
= $ 14 + y *(0.12) ..................(ii)
For having same value in the bank then equation (i) and (ii) shuld be equal to each other
i.e.
16 + 0.08x = 24 + 0.12y
0.08 x - 0.12 y = 24-16
0.08 x - 0.12 y = 8
this will be the equation
Answer:
there were 18 adult tickets were sold and 54 kid tickets were sold so there were 72 tickets sold
Step-by-step explanation:
15 x 18 = 270 x 3 = 810
or if lower 15 x 17 = 255 x 3 = 765
