The solution for the #23 equation is either x=9 or x= -3
10+3.75h=21.25
Subtract 10 from both sides 3.75h=11.25
Divide each side by 3.75, h=3. Kim rented the kayak for three hours.
Answer:
d. y= 5x+18
Step-by-step explanation:
y=mx+b is slope intercept form
Now we plug in the information given to us which is slope(m) is 5 and a point (x,y) which is (2,28).
So by substituting we get 28=5(2)+b
simplify to 28=10+b and when we subtract 10 from both sides to isolate 'b', we get that b = 18.
So now we use the values of slope(m) and the y-intercept(b) to write the equation:
y=5x+18
Answer:
$60 for 10kg of tea leaves.
Step-by-step explanation:
1.- divide $18 by 3kg to determine the price of a single tea leaf.
18/3 = 6
1 tea leaf costs $6
2.- multiply the price of a single leaf by the number of leaves you want.
10 x 6 = 60
