Marlon withdrew $25 from his savings account every week for 5 weeks. Which expression is the best choice to help him determine the total amount of money he withdrew? (5 points) (25)(−5) = −125; he withdrew $125
(−25)(5) = −125; he withdrew $125
(−25)(−5) = 125; he withdrew $125
(25)(5) = 125; he withdrew $125

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

it is 10.6 according to my calculations

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
