Write a one-variable equation or inequality with
variables on both sides to describe the problem
situation. Complete Steps 1 - 2 in order.
1. Step 1: Choose the general form of the equation or inequality for this
situation.
Rhiannon's weekly deposit = Sophie's weekly deposit
the number of weeks elapsed for Rhiannon's account = the number of weeks elapsed for
Sophie's account
Rhiannon and Sophie both started saving for a new
piano this month. Rhiannon will deposit $35.80 per
week, but her bank account is currently overdrawn
with a -$253.50 balance. Sophie also has a negative
bank account balance of - $78.25 and will deposit
$23.30 each week. How many weeks (w) will it take
for the two bank accounts to have the same balance?
Rhiannon's bank account balance < Sophie's bank account balance
Rhiannon's bank account balance = Sophie's bank account balance
Rhiannon's weekly deposit < Sophie's weekly deposit

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
