Q1: Solve the integers: -12 + ( -22) - (-10) -12+(-22)=-34 -34-(-10)=-24 Q2: What is the perimeter of a triangle with sides equal to 11cm, 16cm & 18cm? 11+16+18=45cm is the perimeter of the triangle. Q3: What is the area of a triangle with base equal to 8 cm and height equal to 13cm? Triangle formula: A=½ b+h A=13+8=21 A=21/2 A=10.5cm is the area of the triangle. Q4: What is the area of a square with each side equal to 18cm? Square formula: A=SxS A=18x18 A=324cm is the area of the square. Q5: If the diameter of a circle equals 14 cm, what is the circumference of the circle? Formula: C=πxr2 C= 14/2=7 C=7x3.14 C=21.98x2 C=43.96cm is the circumference of the circle. Q6: What is the circumference for a circle if radius equals to 5cm? Formula: C=πxr2 C=5x3.14 C=15.7x2 C=31.4cm is the circumference of the circle. Q7: Solve the equation for x: 9x - 20 = 16 +20 +20 9x=36 /9 /9 x=4 Q8: Solve the equation for x: 11x + 12 = -54 -12 -12 11x=-66 /11 /11 x=-6 Q9: A family purchased 8 movie tickets for a total of $104. What is the price of each movie ticket? 104/8=13$ Q10: A group of friends bought 12 concert tickets and paid a total of $300. What is the cost of each ticket? 300/12=25$ Q11: Evaluate for x = 12, 3x - 7. Q12: The temperature at night dropped by 12 degrees, leaving it at −20∘C. What was the temperature x before the drop? Equation: x - 12 = 20 -12 x=8 Q13: The temperature outside is x degrees Celsius. After dropping by 8 degrees, the temperature is −15∘C. What was the original temperature? Equation: x−8=−15 +8 +8 x=-7 Q14: The sum of two complementary angles is 90. If one of the angles is 32, then what is the value of the second angle? 90-32=58 is the value of the second angle. Q15: David wrote the following checks: $45.10, $32.50, $75.75, and $210.90. He started with $650.00 in his checking account. Write and evaluate an expression to find his balance. 650.00-(45.10+32.50+75.75+210.90)= 650.00-364.25=285.75$ Q16: Sophia wrote the following checks: $12.50, $85.30, $20.45, and $150.00. She began with $490.00 in her checking account. Write and evaluate an expression to calculate her remaining balance. 490.00-(12.50+85.30+20.45+150.00)= 490.00-268.25=221.75$ Q17: A library had 280 books. After lending out some, there are 147 books left. How many books were lent out? 280-147=133 books were lent out. Q18: Maria buys a book and a notebook for 25% off. The original cost of the book is $18. Her total discount is $9.50. Find the original price of the notebook. Equation: 25%( x + 18) = 9.50 25%/100=0.25 0.25(x+18)=9.50 /0.25 /0.25 x+18=38 -18 -18 x=20 Q19: Sophie is playing a game of tennis. She scores 90 points. In the game she is playing, she loses 4 points each time she faults on a serve. Her final point total is 74. Find how many times she faulted. Equation: 90−4x=74 -90 -90 -4x=-16 /-4 x=4 Q20: Mark is playing a game of basketball. He scored 72 points. In the game he is playing, he loses 2 points each time he commits a foul. His final point total is 56. Find how many fouls he committed. Equation: 72−2x=56 72-2x=56 -72 -72 -2x=16 /-2 x=8
