Answer 1

А) (-11)
б)(-260)
в)-0.18
г)-850.1

Answer 2

Task a)

To solve the equation 5 * (-8) + (-4) * (-2) - (-7) * 3, we can follow the order of operations (PEMDAS/BODMAS) and perform the calculations step by step:

1. Multiply -8 by 5: -8 * 5 = -40. 2. Multiply -4 by -2: -4 * -2 = 8. 3. Multiply -7 by 3: -7 * 3 = -21.

Now, we can substitute these values back into the original equation:

-40 + 8 - (-21) = -40 + 8 + 21 = -12 + 21 = 9.

Therefore, the solution to the equation is 9.

Task б)

To solve the equation (-24 + 78 + 12 - 46) * (-13), we can follow the order of operations:

1. Perform the addition and subtraction inside the parentheses: -24 + 78 + 12 - 46 = 20. 2. Multiply the result by -13: 20 * -13 = -260.

Therefore, the solution to the equation is -260.

Task в)

To solve the equation (-3.6 + 1.8) * (8.5 + (-2.1) * 4), we can follow the order of operations:

1. Perform the multiplication inside the parentheses: -2.1 * 4 = -8.4. 2. Perform the addition and subtraction inside the parentheses: -3.6 + 1.8 = -1.8 and 8.5 + (-8.4) = 0.1. 3. Multiply the results: -1.8 * 0.1 = -0.18.

Therefore, the solution to the equation is -0.18.

Task г)

To solve the equation ((-15) * (-3) + 55) * (-8.501), we can follow the order of operations:

1. Perform the multiplication inside the parentheses: -15 * -3 = 45. 2. Perform the addition: 45 + 55 = 100. 3. Multiply the result by -8.501: 100 * -8.501 = -850.1.

Therefore, the solution to the equation is -850.1.
