1) Evaluate (4 x 6²) ÷2+3. a) 85 b) 75 c) 65 d) 95 2) What is the algebraic expression for "twice a number increased by five"? a) 2x+5 b) x 2 + 5 c) x5+2 d) 5 +2x 3) In Talim island, there are currently 5 tourists. If 7 more tourists arrive each day, how many tourists will be there in 20 days? a) 165 b) 134 c) 154 d) 145 4) If 3x = 12, what is the value of x? a) 4 b) 1/2 c) 2 d) 6 5) Bini Maloi has a grapes and buys b more grapes. She then eats 5 grapes. How many grapes does she have left? a) a + b – 5 b) a + b + 5 c) 5 - a – b d) a - b + 5 6) A rectangular garden has a length of (y + 3) meters and a width of y meters. What expression represents its area? a) 2y + 3 b) y² - 3 c) 2y² + 6y d) y² + 3 7) When solving an equation involving fractions, a student multiplies both sides by the least common denominator (LCD). This step is justified by which property of equality?Addition Property a) Addition Property b) Division Property c) Multiplication Property d) Substitution Property 8) If 1, 2, 3 and 4 are the values of a, b, c and d, respectively. Find the value of x in the equation ax + b = c + d. a) 3 b) 5 c) 2 d) 7 9) Bini Aiah is solving the equation 3(x + 2) = 15. They incorrectly simplify it to 3x + 2 = 15. What property of equality did she fail to apply correctly, and what is the correct next step in solving the equation? a) Bini Aiah failed to apply the addition property of equality; the correct next step is to subtract 2 from both sides. b) Bini Aiah failed to apply the distributive property; the correct next step is to distribute the 3 to both terms inside the parentheses. c) Bini Aiah failed to apply the multiplication property of equality; the correct next step is to multiply both sides by 3. d) Bini Aiah failed to apply the subtraction property of equality; the correct next step is to subtract 15 from both sides. 10) Bini Mikha is budgeting her money. She earns a fixed amount each month (E), spends a certain amount on rent (R), and saves the rest (S). The equation representing her monthly budget is: E = R + S. Bini wants to determine how much she can save each month (S) if she knows her earnings (E) and rent (R). Which formula correctly solves for S? a) S= E-R b) S= R-E c) S= ER d) S= -E-R
