Answer:
Step-by-step explanation:
Let "a" and "m" represent the cost of an apple and a mango, respectively. Then Cameron's purchase can be represented as ...
4a +7m = 17.75
Gavin's purchase can be represented as ...
2a +5m = 10.75
Subtracting the first equation from twice the second gives ...
2(2a +5m) -(4a +7m) = 2(10.75) -(17.75)
3m = 3.75
m = 1.25
Then the price of an apple can be found from the second equation:
2a +5(1.25) = 10.75
2a = 4.50 . . . . . . . . . . subtract 6.25
a = 2.25 . . . . . . . . . . . divide by 2
The price of an apple was $2.25; the price of a mango was $1.25.
The acceleration if the object when force is 100N is 10 meters per seconds squared
<h3>How to find the acceleration of the object</h3>
Given the direct variation relationship
force , f α acceleration, a
f = ka
k = constant of variation
solving for k
90 = k * 9
k = 90/9
k = 10
when force is 100N
100 = 10 * a
a = 100 / 10
a = 10

Make variables for each
L = library books
P = telephone books
T = text books
so.... L+P = 2T
now we have to fill in numbers
