Answer:
y = -20
Step-by-step explanation:
Given that y varies directly with x it means changing x will also cause change in y
Mathematically it can be written as:
y∝x
Removing the proportionality symbol
y = kx
Given y=25 when x=5 Putting the values

Now

We have to find the value of y when x = -4
Putting x=-4

Hence,,
y = -20
Answer:
$20
Step-by-step explanation:
Total cost of items bought
= $31.21 +$12.75 +$13.25
= $57.21
Remaining cost after paying $40
= $57.21 -$40
= $17.21
Amount borrowed
= change +$17.21
= $2.79 +$17.21
= $20

Answer:
C
Step-by-step explanation:
sum of angles in tri are 180
180-35-36=109
15 = 3*5
64= 2*2*2*2*2*2
There are no common factors so the GCF is 1
