Answer:
Y=690-25X
Step-by-step explanation:
Cause she has 690 in the account but takes $25 every month nd it says X is the amount of months so it's 690-25X
Its the same as 10.3 litres
Absolute value (|2|) makes all the numbers in it positive.
|5-9|= -4 with absolute value -> 4
|5|-9: only 5 is in the absolute value:
|5|-9 -> 5-9=-4
number 1: 4
number 2: -4

Step-by-step explanation:
Answer:
y = 18/5(11)
Step-by-step explanation:
If y varies directly as x, this is expressed as;
y∝x
y = kx
k is the constant of proportional constant
if y = 18 and x = 5
18 = 5k
k = 18/5
to get the expression that can be used to find the value of y when x is 11
y = kx
y = 18/5(11)
This gives the required expression
