The equation P = 2.5m + 35 represents the price (in dollars) of a bracelet, where is the cost of the materials (in dollars). 5(-2) = -2(5) Given equation is x – 2/3 = -11/12 2.5(3.5) + 6 = 4.5(3.5) – 1 2m + 3 = 39 x – 6 + 6 = 8 + 6 The temperature outside is currently 23°C -6x + 9 = -6x + 9 The volume of the solution is 3 milliliters greater than 3 times the volume of the solution before the acid was added. 3d = -3 -7/3 = p Each cast member receives a costume that costs $38 and a microphone that costs $c. x = 4. b. b = P – a – c Check your solution. Explanation: Put w = 0 in 5(w – 2) = -2(1.5w + 5) Big Ideas Math 6th Grade Answer Key - Joomlaxe.com On this page you can read or download big ideas math 6th grade answer key in PDF format. c) Convert 300 Kelvin to degree Celsius 2x + 5.2 = 3x + 1.2 Base b = 93.5 sq in Putting x = 0.2 in -7.8x = -1.56 Put w = 2 in 12(2w – 3) = 6w Height of the Millennium Force = 310 Feet putting w = 20 in 0.09w = 1.8 The formula for the volume of a cylinder is V = πr2h, where r is the radius of the circular base and is the height of the cylinder. 3x = 9 P = I/rt, Question 6. (2580 + 2920 + x)/3 = 3000 Then check your solution. Given equation is 1/4 t + 4 = 3/4(t + 8) the distance you ride = distance your friend rides + 3 The length of each side of the pasture is 50 ft, 150 ft, 180 ft, 75 ft. y = -28 What is the value of x? -2z/-2 = 18/-2 = -7 + 4, Explanation: A game of bowling has ten frames. 10 = 3(-5) + 20 – (-5) (1/3)(-9) – 9 = -3 – 9 None of the equation has exactly one solution. You can read Big Ideas Math Blue Answers Grade 8 PDF direct on your mobile phones or PC. Part B Let take y as the original battery life Given equation is 3(x – 4) = -2(4 – x) As shown in the figure Question 26. a. Let us take x as the object weight x = 2 x 3 Answer: putting w = -48 in 6 = -w/8
