A bank records deposits as positive numbers and withdrawals as negative numbers. Mike withdrew $60 from his bank account 3 times. What is the change in Mike's account balance after all withdrawals? a) write the setup (the expression) b) answer as an integer c) answer in a sentence

-$180

Step-by-step explanation:

Mike withdrew $60 from his bank account 3 times.

The bank record withdrawals as negative numbers

a) write the setup (the expression)

= -$60 * x

= -$60x

Where x = number of times Mike withdrew

b) answer as an integer

-$60 * 3

= -$180

c) answer in a sentence

$60 * 3

= -$180

= Negative $180 or minus $180

there are lots of ways.   pick's theorem tells us if the vertices are lattice points the area a is

a = b/2 + i - 1

where b is the number of boundary lattice points and i is the number of interior lattice points.

in the figure i count b=16, i=50 so

a = 8 + 50 - 1 = 57

let's try the shoelace formula.   the area is half the sum of the cross products of the sides.  

a(-2,6)   -2(2)-6(-5) = 26

b(-5,2)   -5(-3) - 2(-2) = 19

c(-2,-3) -2(-3) - (-3)(4) = 18

d(4,-3)   4(3) - (-3)(5) = 27

e(5,3)   5(3) - 3(1) = 12

f(1,3)     1(6) - 3(-2) = 12

a(-2,6)

each of the cross products is twice the area of the triangle with the associated side and one vertex the origin. so the area of abo=26/2=13.

area = (1/2) (26 + 19 +   18 + 27 + 12 + 12) = 57

that checks!

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
