after April 13th Raul would have $535.25 on his account

explanation:

on 4/2 the balance was $539.50
on 4/2 $35.50 was taken out of the account
on 4/6 $23.75 was taken out of the account
on 4/13 $55.00 was added to the account

that means in all, $59.25 was taken out of the account
so, taking it out of the original balance,
539.50 - 59.25 = $480.25
but $55.00 was then added to the account so we add it to the new balance.
$480.25 + $55.00 = $535.25

so, that’s means there is now $535.25 on the account

Answer:

96 degrees

Step-by-step explanation:

The three angles in a triangle add up to 180 degrees. if angle one is 42 the the opposite angle is also 42. 42+42= 84 . Then 180-84 = 96 which would be the last remaining angle. Since the bottom and top triangle are the same the same is true for the bottom triangle.

I think it’s 96 degrees but I’m not to sure :)

Divide 100 by 31:

[tex]100*31=3.22[/tex]

Multiply result by 18:

Sorry if I got it wrong.

48+y=x

Explanation: Since we don’t know how many sugar cookies she made They just consider it as y which means some number we don’t know. Since y is how many sugar cookies she made and the question is asking for how many cookies she made in total we have to add 48+y but we don’t know what the answer will be because we don’t know how many sugar cookies she made so therefore you would just put X or another random variable as the answer.
