QUESTION 1 Evaluate −30 ÷ −6. a 5 b −5 c 6 d −6 QUESTION 2 Evaluate 62 ÷ (3 + 9). a3 b4 c12 d21 QUESTION 3 Danny made a mistake
Mashcka [7]

Answer:

A; ?; Line 3

Step-by-step explanation:

Question 1:

-30 divided by -6 is 5.

The negatives cancel each other out.

And 30 divided by 6 is simply 5.

Question 2:

62\div(3+9)

Do the operation inside the parenthesis first:

62\div12

Divide. 12 does not go into 62 evenly. 12 times 5 is 60, so the answer is 5 remainder 2:

62\div12=5\text { R}2

Or in fractions:

31/6

(Was there a typo? From what you've given me, the correct answer is not listed.)

Question 3:

So we have to following steps:

\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+11(2)\\\text{Line 4: }21+22\\\text{Line 5: }43

The mistake is in Line 3. Danny cannot just combine 5+6(2) into 11(2). Instead, he should multiply 6(2) and then add. Thus, the correct solution is:

\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+5+12\\\text{Line 4: }26+12\\\text{Line 5: }38

Solve for b.<br> -1lb + 7 = 40
MariettaO [177]

Answer:

b = -33/l

Step-by-step explanation:

-1lb + 7 = 40

-1lb = 33 (subtraction property of equality)

-1lb/l = 33/l (division property of equality)

-1b/-1 = -33/l (division property of equality)

b = -33/l (solved)
