Answer:
20 miles.
Explanation:
2x + 20 = 3x
x = miles driven
The left side of the equation represents Laguna's, and the right side Salvatori's.
You can multiply the miles driven by their price per mile. This gives you (2x) on the left, for Laguna's $2 per mile, and (3x) for Salvatori's $3 per mile.
The (+20) represents the initial payment for Laguna's, but Salvatori's doesn't have this, so we can leave it out.
Finally, eliminate.
Subtract 2x from 3x on the right. This leaves you with 20 = 1x.
Answer:
Step-by-step explanation:
120/6.4=20
It will take her 20 days
Jummai and Tunde will each have 9 and 6 bananas respectively.
For the given ratio case we use the sharing ratio criterion to solve the problem.
Jummai is 12 years old.
Tunde is 8 years old.
Their ages are in ratio of;
A = 12 : 8
A = 3 : 2
The ratio's sum is 5.
15 bananas total are available for sharing.
Jummai will have 
bananas 
= (15 x 3/5) = 9
Tunde will have 
bananas = (15 x 2/5) = 6
Jummai and Tunde will each have 9 and 6 bananas with them.

Answer:
y=-2x+11
Step-by-step explanation:
equation of a line
y-b=m(x-a)
m=-2
a=3
b=5
sub into the equation
y-5= -2(x-3) multiply out the brackets and a negative multiply by negative equals positive
y-5=-2x+6
y=-2x+11
or
2x+y-11=0
