Answer:
Step-by-step explanation:
Given that:
Keiko sold 3 less than three-fourths of his sister's sale.
To find:
Expression that represents what Keiko sold ?
Solution:
First of all, let the sales done by Keiko's sister =
Now, let us consider the Keiko's sale word by word.
3 less than three-fourths of his sister's sale.
- Three fourth of his sister's sale i.e.
- 3 less
i.e. subtract 3 from the expression obtained in 1st line.
So, sales done by Keiko =
So, correct answer is:
Answer:
y = (8/7)x
Step-by-step explanation:
We can see that this line intersects with the points (0,0) and (21,24).
The equation of this line is y=mx (y-intercept is 0).
The slope is the change in y over the change in x.
24-0/21-0 = 24/21 = 8/7
y = (8/7)x

2800 miles.
It takes one hour to go 350 miles, so if you multiply 350(miles) x 8(hours), you will get 2800.
C is the closet to the real answer and its a estimate so, C
(50-(x*50))+(40-(y*40))+20= discounted with 2 coupons
110-(z*110)= the price with the total coupon.
I believe these are the correct answers
