1. solve for p. 3(p + q) = p (1 point) • q = –p • q = –p • p = –q • p = –q 2. solve for b, then find the value of b when a = 3. 4a = 2b − 7 (1 point) • – • 17 3. solve for r. d = rt (1 point) • r = dt • r = • r = d − t 4. find the width of a rectangle with a perimeter of 90 and a length of 15. (1 point) • 90 • 15 • 45 • 30
1. 3( p + q ) = p 3 p + 3 q = p 3 p - p = - 3 q 2 p = - 3 q p = - 3/2 q 2. 4 a = 2 b - 1 2 b = 4 a + 1 b = 2 a + 1/2 When a = 3: b = 6 + 1/2 = 6.5 3. d = r t r = d / t 4. P = 2 L + 2 W 90 = 2 * 15 + 2 W 90 = 30 + 2 W 2 W = 90 - 30 2 W = 60 W = 60 : 2 W = 30
You are remodeling your kitchen. you’ve contacted two tiling companies who gladly told you how long it took their workers to tile of a similar size jim completed half the floor in 8 hours. pete completed half of the other floor in 7 hours. if pete can lay 20 more tiles per hour than jim, at what rate can jim lay tiles
