Final answer:
To solve -7 - [-80 / (-8)], first simplify the division, then subtract. To solve -2(-17 + 5), distribute -2 and simplify the expression.
Step-by-step explanation:
To solve the expression -7 - [-80 / (-8)], we need to apply the order of operations. First, we simplify the division inside the brackets: -80 / (-8) = 10. Then, we can rewrite the expression as -7 - 10. To subtract, we change the sign of 10 and add: -7 - 10 = -17.
To solve the expression -2(-17 + 5) using the distributive property, we distribute the -2 to both terms inside the parentheses: -2 * -17 + (-2) * 5. Simplifying further, we get 34 + (-10) = 24.
