Answer:
Required Expression : 7·(s + d) - 25
Step-by-step explanation :
Cost of each plant both buys = $7
No. of plants Stephanie wants to buy = s
Total cost of plants bought by Stephanie = 7·s
No. of plants Diego wants to buy = d
Total cost of plants bought by Diego = 7·d
Total cost = 7·s + 7·d
= 7·(s + d)
Discount applied through coupon = $25
So, Total cost of all their plants with discount = 7·(s + d) - 25

Answer:
10 km
Step-by-step explanation:
volume of cube = s^3
1 m = 100 cm
volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3
Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.
1,000,000 cm = 10,000 m = 10 km
Answer:
Step-by-step explanation:
Given

Determine the percentage of protein
First, we need to calculate the total:
Percentage of protein is calculated as thus:
X=price of one jumbo popcorn
y=price of one chocolate chip cookies
$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts
We suggest this system of equations:
x+2y=500
x+4y=600
we solve this system of equations by reduction method.
-(x+2y=500)
x+4y=600
----------------------
2y=100 ⇒ y=100/2=50
x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400
solution: one chocolate chip cookie cost 50 cts.
