<span>If QRST is a rectangle with QT = 50 and RS = 4x + 8, find x.
.
QT = RS (opposite sides of a rectangle are equal)
50 = 4x + 8
42 = 4x
10.5 = x</span>
The garden club earned $15 per hour by weeding neighborhood gardens for t hours.
A generous donor has agreed to double their earnings.
Double their earnings means we multiply by 2
So earning 15 per hour becomes 2*15 = 30 per hour
Given the number of hours is t
Earnings = $30 times number of hours
Earnings = 30 * t
Can you show the paper more? I can't see what I need to know in order to solve it...
