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

The total cost in dollars for Larry to have his birthday party at a local
luda_lava [24]

Answer:

0 \leq p < 6

Step-by-step explanation:

Given

t = 6.95p + 29.95

Amount = 70

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in t = 6.95p + 29.95

70 = 6.95p + 29.95

Collect Like Terms

6.95p = 70 - 29.95

6.95p = 40.05

Solve for p

p = 40.05/6.95

p = 5.76

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: 0 \leq p < 6

Answer:

The answer to your question is 1 = 69°

Step-by-step explanation:

To solve this problem remember that the sum of the internal angles in a triangle equals 180°.

Let the third angle of the triangle be x.

             39° + 30° + x = 180

Solve for x

             x = 180 - 39 - 30

             x = 111°

Angle x and angle 1 are supplementary so their sum equals 180°.

            111° + 1 = 180

                      1 = 180 - 111

                       1 = 69°
